CE Messenger [PART TWO]

xero · 2009-04-17T19:33:30+00:00

Continued from: #-Link-Snipped-# Hey people, its about time to start making pieces and join them. So we'll start with HOWTOs for making pieces. For a development environment, first of all we'll need all the components needed for server (Hamatchi optional). Apart from that we'll need the following components :- 1. Java development IDE : Eclipse / Netbeans (I'll be using Eclipse) 2. J2SE 5.0 or above 3. Smack ver 3.1.0 api (link <a href="https://www.igniterealtime.org/downloads/index.jsp#smack" target="_blank" rel="nofollow noopener noreferrer">Ignite Realtime: Downloads</a>) However before proceeding with above stuff I would like to know how many aren't aware of basic OO concepts, as we'll follow these strictly in our project. I'm also expecting that atleast developers have their hands on with server, and have tested with Spark client 😀 And since Shalini is pretty good at teaching, she can help most of you out ! Shoot questions if any ! Happy Learning

I am having experience with servers like, J2EE server,tomcat, and netbeans,,so I can use the netbeans..I did not use spark...just here I heard about that...What is use of smack api.? It is a time to start...

xero

@xero-28ehVN • Apr 18, 2009

um.. well we really won't be needing any server as of now and if you are comfortable with Netbeans as your IDE its fine 😀

Spark is just used to test the openfire server configuration.If you haven't done it i would suggest you try to use it once, as our ce messenger functioning would be on similar lines

With the help of smack api we would communicate with the openfire server through java code.

hey, I'm sorry for the late reply, I'm pretty caught up on weekdays so, cannot visit CE on weekdays. Well tomorrow (Saturday) I'll be posting first patch of code for a basic authentication with the server. I'll put it in as simplistic manner as possible and will give a brief explanation on it. After that I want to try and run the code, with results to be posted in this thread !!

@XERO

did anyone say "U ROCK?"

xero

@xero-28ehVN • Apr 25, 2009

Thanks for the compliments Durga, but we all rock 😁

The code for basic authentication and chat functionality for created users in server is as follows..

// Create a connection to the igniterealtime.org XMPP server.
XMPPConnection con = new XMPPConnection("serverAddress");
// Connect to the server
con.connect();
// Most servers require you to login before performing other tasks.
con.login("username", "password");
// Start a new conversation with John Doe and send him a message.
Chat chat = con.getChatManager().createChat("username2@localhost", new MessageListener() {

public void processMessage(Chat chat, Message message) {
// Print out any messages we get back to standard out.
System.out.println("Received message: " + message);
}
});
chat.sendMessage("Howdy!");
// Disconnect from the server
con.disconnect();

Now that sure looks pretty easy isn't it 😀

The smack API, as mentioned before provides us with a class called XMPPConnection.
This object is responsible for establishing a connection between the program and server and authenticate with credentials.
Then we instantiate a Chat object which handles the chatting process with another user.

The above code has been extracted from #-Link-Snipped-#

I really want everyone to try the above code. If not to send a message atleast try creating a single user at server and authenticate it via this code. With this you'll be able to get a whiff of how to start with the code 😀

Now those who really couldn't understand what's happening in the code really need to look forward for java tutoring which Shalini had given.

@Xero:nice start...Shall I know the plan of IM?Then only I can understand what is really happening...

I have sucessfuly compiled with smack api...How to test it? via a browser using jsp? or through command line? How to test that?

0

xero

@xero-28ehVN • Apr 25, 2009

Well to start with, we'll first need people to have a good hands on with smack API. So for that we'll play with the API for 2-3 weeks going through assignments like authentication, creating users, chatting etc..

As per for testing, the above code create two users in server. Log in with one of the users through spark and then use the above program to log in the second user. As an output, you'll the user logged in with spark receive the message "Howdy" 😀

That's the test...

Similarly you can create a console program which can at least send a spark based user messages. This is a good assignment to start with.

How to run the program ? Is it similar to run the ordinary java programs?

0

xero

@xero-28ehVN • Apr 25, 2009

This is just and ordinary java program. Put the whole code in main method, and run it. The issue you reported is related to classpath .

If you are using Netbeans/Eclipse i don't think you'll face this issue. Also make sure before running the program that the openfire server is up and running properly.

If you continue to seek the problem, try google 😀

}

This program is to display offline messages.
I have created two users u1,u2; And using spark logged using u1 account.
And Through u1 I add u2 to my contacts in spark and sent messages to u2[which is offline message]. I run the above program to get those offline messages...It runs ,,,But displays message as null...Why this program fails to display the offline messages?

Can I use ChatManager class,Chat,MessageListener? What are the classes I have to use to chat?

xero

@xero-28ehVN • Apr 27, 2009

To begin with, you can go through the API Documentation of all the classes which we use in the program. It will help you gather a pristine idea, on how to proceed 😀

And use your own imagination 😁

Firstly sorry for not replying for a while, i was out on a much needed vacation.

I guess durga and ms_cs should help out shalini in all possible ways with the setup issues, so that ev'1 is at the same place for pick off.

And as i had told earlier, we'll spend some time with hands on API before starting with the actual development.

MaRo seems to be busy these days, however i believe that he won't have any problems in picking this up 😀

@ms-cs-Ab8svl • May 5, 2009

Yes.I will be available after 10IST...I have followed the steps in the document.It works fine now.

whether these steps worked fine for you?

Step 1: Unpack the package into a directory of your choice. Please start the
"setup_xampp.bat" and beginning the installation.

Step 2: If installation ends successfully, start the Apache 2 with
"apache_start".bat", MySQL with "mysql_start".bat". Stop the MySQL Server with "mysql_stop.bat". For shutdown the Apache HTTPD, only close the Apache Command (CMD).

Step 3: Start your browser and type #-Link-Snipped-# or #-Link-Snipped-# in the location bar. You should see our pre-made
start page with certain examples and test screens.

Hey team, i'm really happy to see the progress on Shalini's environment and i'm really grateful to ms_cs and durga for helping her. However there's one thing which is bugging me, and its the doc.

Thanks to Durga's efforts the first version of doc came alive and it was helpful for all of us, however I don't want to limit the document as "Durga's doc" any more. I want every member of team who has done the environment setup to update the document and add FAQs which could help the future team members.

For example the DB setup is not mentioned in the document, its NOT responsibility of durga to do it. Everyone is equally responsible for its absence.
Ms_cs if you are done with the database setup kindly update the document with its steps.

I'm yet to setup dev environment and will update the document. I've been holding it up due to some operating system issues. However i'll be regular with the code updates.

PS: kindly call the doc as CE:IM doc 😀 (I hope Durga won't mind for this !)

on XAMPP control panel click on EXPLORE in the right hand side

then navigate xampp>apache>logs

may be I can help you out if I can see what's in logs

By the way the XAMPP control panel what you have posted, shows that APAche is busy.. I doubt if that is the issue.

@Durga Thanks but files in log folder were simply showing blank.😀 so no idea one can get from it.

Anyways I have figured out problem and luckily all server setup as well as database set up is done successfully at my end. 😁

I have prepared a much better doc and have mentioned problems clearly step wise one by one an individual can face at different stages of environment setting.If anyone need that(especially Maro), that will do all your work max to max in 1 hour only 😁

@xero Now my next question is I have just created a dummy "aikon" database but what all tables we are supposed to create in it ? Oh yes , testing through Spark client is still pending for me, I guess for it my username need to be added in database. Can you put some more light on Database related things like what all tables are there(if have any) and privileges and accesses and etc..?

Get set ready for development part soon Please.....

Thanks to all for bearing my problems. ! 😀

@xero-28ehVN • May 8, 2009

Congratulations shalini on setting up the servers 😀

Now if you have provided the correct database parameters while configuring the openfire server, the aikon database would have been used by openfire all by itself for the schema creation. As of now we may not need to manually override the existing schema. As per for priviledges we really don't need to think it of it during the development phase, however we'll take it on during later stages.

@xero-28ehVN • May 8, 2009

start the openfire administration web console. Search for the users link. From there you can create users.

From the spark client use those credentials along with the server ip address, which would be localhost and start using it 😀

My proposed timings:
Weekdays + Weekends Around 10 PM IST

@ms_cs Cool timings. If you find your rest of team fellows BUSY, don't waste time (if you have any). Go through with Smack API and Openfire things. This information could be of help to your rest of team as well as you also. 😀

guys,

can it be made a little earlier?
Its really not possible for me to be available at 3 am here 😀

It would be difficult for me to attend discussions at nights. So i'm proposing a small protocol for meetings and let me know if its fine by you all..

Whole team must try to meet once a week especially on either of weekends in a way that timing is convenient for all e.g
we can meet at Saturday sometime in the morning like 11 am to 1pm(considering the convenience at timezones of all team members).

The purpose of the meeting will be as follows
--the status of last weeks work and next weeks work plan.
--technical issues facing if any. The technical issues will be taken up only during the initial meets as we all are new with this. However as we proceed it would be preferable if we take it via threads just to avoid lengthy meetings.

Now meetings should have agendas, so the agenda will be put up on the day before the meeting. And i want everyone to come up with it. Now obviously we won't be able to take it all but will try to keep everyone's interest with it 😀. So try to make sure that agenda goes in everyone's interest

In case somebody will not attend the meeting kindly intimate the other team members.

I would prefer skype meets, instead of IMs, if that's not a problem.

After the meeting the minutes of the meeting will be posted in the thread.

Kindly let me know if i'm missing anything.

Happy learning

In addition to what i just posted, it would be really nice if all team members can interact one 2 one with each other as per their convenience. It would really help in knowing each other and will help to work as a team !!

In the mean time I also want all developers to start studying about the object oriented principles and their applications. It would benefit us in a great deal with the project.

Happy Learning !

@xero So that means this CE-IM is going to get completed in years rather than in months. Now wait for one more week(Today is Sunday) to just get start with actual work. Whole week no activity on this project. OK no problem. * Sighs * 😐 I don't think so that spending just 1 hour a day could be a problem to anyone. Anyways I will just follow you guys.

Tell me my work, I am still not able to follow the useful posts of this CE-IM thread.😕 What xero and ms_cs have done till now? I really have no ideas. I am just after at server settings stage. Next what I am supposed to do? ?

@ms_cs If you know, you can also answer my questions ok.

If it is working by putting infinite loop that means problem is there only. It should get login by using only con.login() once.

I will look into it today and will surely get back to you tonight. OK , by that time you also keep on trying and update this thread if solved. 😀

One more thing, it worked for you by using Offline Manager? I will check your program also tonight.

@xero-28ehVN • May 11, 2009

Hey all,
Following is a very small program, which can enable two users to chat with each other, without SPARK as long as you want 😀

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

import org.jivesoftware.smack.Chat;
import org.jivesoftware.smack.MessageListener;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Message;

public class BasicSmackClient {
public static void main(String[] args) {
XMPPConnection connection = null;
try {
boolean closeChat = false;
String username=null, password=null, recipient=null;
connection = new XMPPConnection("127.0.0.1");

connection.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.print("Enter username : ");
username = br.readLine();
System.out.print("Enter password : ");
password = br.readLine();
connection.login(username, password);
System.out.println("Login successful");
System.out.println("Welcome to smack client\nType 'close' to exit the progam");
System.out.print("Enter message recipient : ");
recipient = br.readLine();
if(recipient.equals("")){
recipient=username+"@127.0.0.1";
}else
recipient+="@127.0.0.1";

Chat chat = connection.getChatManager().createChat(recipient, new MessageListener() {
public void processMessage(Chat chat, Message message) {
System.out.println(message.getFrom()+": " + message.getBody());
}
});
String message;
while (!closeChat) {
System.out.print(username +" : ");
message = br.readLine();
if(message.equals("close"))
closeChat = true;
else
chat.sendMessage(message);
}
System.out.println("Exiting from client. Thanks for using it");

} catch (XMPPException e) {
System.out.println("connection error");
}catch(IOException ioe){
System.out.println("IO error");
}finally{
connection.disconnect();
}
}
}

All you need to do, is run two instances of about code, login one with user1 and set recipient as user2 and login the second with user2 and use recipient as user1 😀

Try to execute it and let me know the results.

As per the OfflineMessageManager, it seems like the server will only flush the offline messages if user will intimate the server of its Presence. Well we haven't used any Presence stuff here, so kindly ignore that as of now.

You can edit the above code as per you requirements.

Have FUN !!

Happy learning

Hey xero,
Just now I tried the above program

I have a user with username: user and I login it through Spark and I have one more user with username: shalinig and I login it through the code. I tried sending a message "hello" from Spark to shalinig

user: hello

Folowing is what happened at my side when I tried to run above program.

Enter username :
shalinig

Enter password :
shalinig

Login successful
Welcome to smack client
Type 'close' to exit the progam
Enter message recipient : user
shalinig :
hello

shalinig : user@127.0.0.1: null

Where could be problem ? Any ideas?

0

xero

@xero-28ehVN • May 11, 2009

I'm expecting that you have created two users in the openfire named shalinig and user.

Now you can continue either way. 2 instances of above code or one instance of above code and another user in spark.

Steps for the later procedure:

1. Login spark with user user
2. start the above program and login as shalinig and message recipient as user

Try the above steps and let me know.

shalini_goel14

@shalini-goel14-ASmC2J • May 11, 2009

Yes I have created both the users in Openfire first and checked their credentials through Spark also.

I tried your told second procedure and transferring of messages is not happening. The similar kind of problem I was facing with your earlier piece of code also.

@shalini-goel14-ASmC2J • May 12, 2009

Those who are facing problem as mentioned by me in post # 95 in this thread, Please make sure that domain given while setting server in openfire exists. Better give it as localhost. If done wrong, no issues Go to Server settings in Openfire and change xampp.domain entry to 'localhost' there.

My problem solved.Hope it may solve your problem also. 😀

@Maro I am still waiting for your posts in this thread. Be fast and quick 😀

Next step: Play with Smack API using latest code shared by xero in this thread and can follow following doc for Smack

So I won't be available till June. However if i got sometime i'll keep posting code snippets along with brief explanations 😀
In the mean time, if interested you can take the following assignments:
1. Creating a program for chatting with multiple users over the console
2. Learning about Roster and Presence

Keep posting the codes in the thread, if possible I can help with the issues.

Sorry for the inconvenience.

You want me to make a single program for allowing multiple users to login-right? Done
You want me to allow all users to do chat using same console window or want me to make use of Swings in a single program for opening separate window for each login?

Please make it clear if possible and have time.

Hey xero,

I tried a test Program for use of Roster for knowing the status of all contacts added in one's list(here example of "User" )

package com.crazyengineers.im.authentication;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Collection;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Presence;
/*
 * author shalinig
 */
public class RosterTest {
  public static void main(String[] args) {
   XMPPConnection connection = null;
   try {
    String username = null, password = null;
    connection = new XMPPConnection("127.0.0.1");
    connection.connect();
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    System.out.print("Enter username : ");
    username = br.readLine();
    System.out.print("Enter password : ");
    password = br.readLine();
    connection.login(username, password);
 
    Roster roster=connection.getRoster();
 
    /* Gives the list of contacts added */
    Collection<RosterEntry> entries=roster.getEntries();
 
    for(RosterEntry entry: entries){
     Presence presence=roster.getPresence(entry.getUser());
     if(presence.getType()==Presence.Type.available){
      System.out.println(entry.getName()+" is online.");
     }
     else{
      System.out.println(entry.getName()+" is offline.");
     }
 
    }
 
   } catch (XMPPException e) {
    System.out.println("connection error");
   } catch (IOException ioe) {
    System.out.println("IO error");
   } finally {
    connection.disconnect();
   }
  }
 }

In above program contacts list for "User" is as follows (as seen from Spark currently )

[IMG]

So above piece of code when made run without Spark would give the output as follows:
Output:

Enter username :

user

Enter password :

user

Shalini is online.

Admin is online.
User1 is offline.
User2 is online.

It shows all the contacts added in the list of "User" alongwith their Presence status.

Please check if I am going on right track. 😀

Thanks !

why to go with pure AJAX, when there are good readymade AJAX components available.
there are some AJAX Frameworks also. Anyways considering ajax means we are going to make web version of this CE-IM, are we also going to make standalone app just like spark???
would be good if are clear on our strategies, and do have real plans instead of only bieng serious about making it...

Shalini, please don't consider that I'm pointing a single being for handling a project, If out of last 13 pages of discussion on this thread and just 3/4 snippets of code is making you feel that I'm relying on single person for the whole project then I regret for such an impression.

Manusaluja, using AJAX was just an idea. I'm familiar with the frameworks but again as you mentioned, currently we are targetting to make something like the spark client 😀 and kindly don't use words such as strategies and real plans, i really find them overrated 😁

MaRo, as of now we'll make a desktop application for a start. However we can think on a final concrete interfacing later on. Our primary goal for this thread is however a basic desktop agent with max functionalities covered similar to a spark client.

1. Development environment setup and testing with spark
2. Introduction to smack api by examples of api usage of chat, Roster and presence.

Even though our primary aim of this thread was to end up with a stable console based program with basic functionality, the current progress is appreciable 😀

The rest of thread will primarily comprise of QnA regarding the things we've done yet. In the mean time i'll start a new thread with their objectives 😀

public class offreader {
private static List<String> nodes;
public static void main(String[] args) throws Exception {
XMPPConnection con = new XMPPConnection("localhost");
con.connect();
con.login("u1", "u1");
OfflineMessageManager off=new OfflineMessageManager(con);
off.getMessages(nodes);
System.out.println(nodes.get(0));
con.disconnect();
}
}

This program is to display offline messages.
I have created two users u1,u2; And using spark logged using u1 account.
And Through u1 I add u2 to my contacts in spark and sent messages to u2[which is offline message]. I run the above program to get those offline messages...It runs ,,,But displays message as null...Why this program fails to display the offline messages?

Getting an offline message ain't that easy as it looks. Jabber protocol has mentioned a way on how to get an offline message. Its binded with some subscription of presence of a user.

If possible try to find an ebook
Instant Messaging in Java - The Jabber Protocols

Again, before using the api its better if you can go through the Jabber protocol before through the smack api. It will cover most of the How-To(s).

Hello everyone,

I went through CE-IM Document shared by Shalini as well as snippets of code shared in this thread. Assuming that being a CEan as well as having enough capability I can join and contribute in this project, I have come out with some basic "Login Page" in Java Swings that allow any user to login and check credentials.

What all steps I followed to start with

Step 1: Set up the environment as mentioned in CE-IM Doc shared by Shalini.

Step2: Created two users using OpenFire

User 1:
Username : admin
Password : password

User2:
Username : cemember
Password : cemember

Step 3: Downloaded Smack Api 3.1.0 from following URL
<a href="https://www.igniterealtime.org/projects/smack/" target="_blank" rel="nofollow noopener noreferrer">Ignite Realtime: Smack API</a>

Step 4: Download and installed Netbeans IDE in my local.

Step 5: Created following as the project strcuture

Step 6: Create LoginPage using Java Swings. Following is the program for it. [Note: If anyone else is interested in this, can modify it to make better.]

}

As the above program is made using NetBeans IDE so lot of code might go over your head as it is auto-generated by IDE and not allowed to edit even.

Step 7: When the above code is made to run following output comes. [Please don't laugh - it is just a rough and quick made stuff. Also I have never worked on Swings.First time I made program in Swings.:sshhh: Image used is stolen from CEan Kashish's made GFX. 😐] .

[IMG]

Step 8: Enter anything in Username and Password textfields - you will get following screen

[IMG]

As we entered wrong username so it is quite obvious - "Invalid credentials" message will be displayed.

Step 9: Now I will enter credential of user1 created in Step 2 [username:admin & password: password ]. [ Currently following screen would be shown though ideally it should take the user to other window that will show list of contacts and other many features(need to be developed) required to be a part of any messenger. ]-UPDATED TO - [Following window will appear but it requires complete designing according to the needs.]

[IMG]

So far this is done. Feel free to ask any doubts regarding coding part.Also you all are free to change code to the BEST look and working. 😀

@Maro & @xero Sir, Please give your feedbacks - soon I will come up with a "Phase1 flow diagram" showing what all we can do so that if anyone else interested in this project can get an idea of to do things. One request -it would be really appreciating if both of you or senior CEans can show some interest here. * May be we can have atleast this project completed 😀 *

If anyone else is interested please try to make a UI page[Right now using Swings] for next window that need to be shown after successful login for user. Logical part to be done, I will look into it by that time. OK?

Thanks a lot for feedbacks and support ! 😀

[
Update:
Code is updated to show a new window[Main Window] on successful login of user. Also corresponding pic for it is also changed. Changed and important coding part is showin in blue colour.

Hey xero,

I tried a test Program for use of Roster for knowing the status of all contacts added in one's list(here example of "User" )

package com.crazyengineers.im.authentication;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Collection;
import org.jivesoftware.smack.Roster;
import org.jivesoftware.smack.RosterEntry;
import org.jivesoftware.smack.XMPPConnection;
import org.jivesoftware.smack.XMPPException;
import org.jivesoftware.smack.packet.Presence;
/*
 * author shalinig
 */
public class RosterTest {
  public static void main(String[] args) {
   XMPPConnection connection = null;
   try {
    String username = null, password = null;
    connection = new XMPPConnection("127.0.0.1");
    connection.connect();
    BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
    System.out.print("Enter username : ");
    username = br.readLine();
    System.out.print("Enter password : ");
    password = br.readLine();
    connection.login(username, password);
 
    Roster roster=connection.getRoster();
 
    /* Gives the list of contacts added */
    Collection<RosterEntry> entries=roster.getEntries();
 
    for(RosterEntry entry: entries){
     Presence presence=roster.getPresence(entry.getUser());
     if(presence.getType()==Presence.Type.available){
      System.out.println(entry.getName()+" is online.");
     }
     else{
      System.out.println(entry.getName()+" is offline.");
     }
 
    }
 
   } catch (XMPPException e) {
    System.out.println("connection error");
   } catch (IOException ioe) {
    System.out.println("IO error");
   } finally {
    connection.disconnect();
   }
  }
 }

In above program contacts list for "User" is as follows (as seen from Spark currently )

[IMG]

So above piece of code when made run without Spark would give the output as follows:
Output:

It shows all the contacts added in the list of "User" alongwith their Presence status.

Please check if I am going on right track. 😀

Thanks !

@CEMember: this code can be used to check the presence of users.

Ok guys, FTI [For Those Interested ] - my previous first step code is changed so that a new window[Main Window] is opened now on successful login of user.

Now those who have good hands on Java Swings and have interest in graphics designing, can change following method in my previous code. Changes can be like - menus and icons . Also my previous code was just a rough design , if any one can change it to better -it will be really appreciating. 😀

private void submitButtonActionPerformed(java.awt.event.ActionEvent evt)

Coming soon with sending and receiving messages thing. Please give some time 😀 By that time , if anyone can work on design of this "MainWindow". Also one more thing need to be done by that time is closing of "Sign In" window when "Main Window" opens.

Thanks !

Hi every one ,
Recently I have made few changes in Project structure , so following respective changes are done in my last to last post

1. Image of Project Structure is updated .
2. Code of following method is also changed. See last to last post for updates.

private void submitButtonActionPerformed(java.awt.event.ActionEvent evt)

3. A new J Frame class called as "MainWindow" is created. Its code is as follows at present. [Soon going to update :sshhh: ]

/*
 * MainWindow.java
 *
 * Created on July 6, 2009, 9:49 PM
 */

package com.crazyengineers.im.webpages;

/**

public class MainWindow extends javax.swing.JFrame {
    
    /** Creates new form MainWindow */
    public MainWindow() {
        initComponents();
    }
    
    /** This method is called from within the constructor to
     * initialize the form.
     * WARNING: Do NOT modify this code. The content of this method is
     * always regenerated by the Form Editor.
     */
    // <editor-fold defaultstate="collapsed" desc="Generated Code">
    private void initComponents() {

        TempLabel = new javax.swing.JLabel();

        setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

        TempLabel.setFont(new java.awt.Font("Comic Sans MS", 0, 14));
        TempLabel.setForeground(new java.awt.Color(255, 0, 0));
        TempLabel.setText("Login Successful !!!");

        javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
        getContentPane().setLayout(layout);
        layout.setHorizontalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addGap(71, 71, 71)
                .addComponent(TempLabel)
                .addContainerGap(84, Short.MAX_VALUE))
        );
        layout.setVerticalGroup(
            layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
            .addGroup(layout.createSequentialGroup()
                .addGap(103, 103, 103)
                .addComponent(TempLabel)
                .addContainerGap(355, Short.MAX_VALUE))
        );

        pack();
    }// </editor-fold>
    
    /**
     * @param args the command line arguments
     */
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new MainWindow().setVisible(true);
            }
        });
    }
    
    // Variables declaration - do not modify
    private javax.swing.JLabel TempLabel;
    // End of variables declaration
    
}

MainWindow would appear as following at present :
[IMG]

---------------------------------------------------------

Also one more thing need to be done by that time is closing of "Sign In" window when "Main Window" opens.

This problem mentioned by me in my last post is solved now.

PS: Coming soon with "Sending and Receiving messages" thing also. Please give some more time 😀 Again saying by that time , if anyone can work on design of this "MainWindow" class , it will be really appreciating.

Thanks ! 😀

I have a question Mr xero Sir, if you are reading my this post by chance 😔. Do we need to maintain "session" for the logged in user or not? If yes, how we are supposed to do that, any ideas?

Thanks for replying as soon as possible ! 😀

Hey guys,
Sorry I've been out for quite a while now, and really sorry for leaving the thread just like that !!

CEM, I really appreciate your hard work and time you are giving for the project and also sorry for not carrying out my "responsibilities" 😀.
I'm just looking at the code and will tell you the way to maintain a session.
PS: I prefer ignoring your comment !

I'll just go through the thread from where I left, and will continue this thread.

CEM, once you log in using XMPPConnection.login, you can disconnect using XMPPConnection.disconnect.
Following is a sample snippet which can provide you a scenario to disconnect.

addWindowListener(new WindowAdapter(){
public void windowClosed(WindowEvent we) {
try{
con.disconnect();
System.exit(0);
}
catch(Exception e){}
}
});

So in the above code on closing a window I'm disconnecting the connection that I had established on application initialization. So that way you are maintaining a session between the XMPPConnections.login and XMPPConnection.disconnect

Was this the info you were expecting?

Hey Sir,
Thanks for the info. but I don't think so it will work because if you see my submit() method or your old code only, in that connection.disconnect(); statement was added in finally() block that means if I comment it, the connection should remain opened right? So no need of Window Listeners right but problem is I just want the logged in user's name and password values from my first page "LoginPage.java" in "ChatWindow.java" where sending and receiving messages code will start. Well, I somehow managed to get the Connection object there but still not getting username and password. Don't know going right way or not but still trying, will let you know if done.

Please feel free to correct if going wrong.

Thanks !

You can pass the username from the LoginPage.java to ChatWindow.java by passing them as parameters to constructor of MainWindow.java.

MainWindow mainWindowFrame = null;
try {
String username = null, password = null;
connection = new XMPPConnection("localhost");

connection.connect();
username = userNameTxtField.getText();
System.out.println("Username : " + username);
password = passwordTxtField.getText();
System.out.println("Password : " + password);

connection.login(username, password);
// you can pass the credentials as the parameters
// by simply passing them as parameter to constructor
mainWindowFrame = new MainWindow(username, password);

mainWindowFrame.setVisible(true);
this.setVisible(false);

} catch (XMPPException e) {
messageDisplayLabel.setText("Invalid credentials !!");
} finally {
connection.disconnect();
}

Can this solve your problem ?

Hey! Man, thanks a lot, it worked though not the way I wanted 😉 but still something is always better than nothing. Why this simple thing didn't striked my mind before.:sshhh:

Just one problem I may face now, is login again with what username and password I will receive in my ChatWindow program to start sending and receiving messages. I was thinking if there could be any such way so that as soon as user logs in , his connection remains active throughout chatting until he signs out. Well, that is not current headache. Your thing worked. I will come up with sending and receiving thing soon. 😀

Thanks a lot !

[Update: Man, no need for thinking of maintaining connection alive. It is done now. Now I need not to add login code again in ChatWindow. 😀 ]

OK, Guys !

Now few things I have done a step ahead more

Updated Working scenario of CE-IM :

Step 1: Login Window. User Logs in. Code is bit changed now for this class. Username ="Admin" and password ="password" at present.
[IMG]

Step 2: Main Window opens showing list of all users added in the contact list of logged in user.[Right now contact is hardcoded. "cemember" -coding part need to be change later for this. ]

[IMG]

Step 3: User clicks on the name of any contact added , a "ChatWindow" appears for the logged in user.

[IMG]

Step 4: The added contact "cemember" at present logs in and chats through "Spark" right now.

[IMG]

Step 5: A smooth conversation starts at present. 😀

Appearance of chat window at "Admin's" end
[IMG]

Appearance of chat window at "cemember's" end
[IMG]

PS: Coding part in next post as this poor CE system allows only 20000 characters 😔

                        public void processMessage(Chat chat, Message message) {
                            chatAreaText.append("\n" + message.getFrom() + ": " + message.getBody());
                            ChatTextArea.setText(chatAreaText.toString());
                        }
                    });
 
               message = MessageTextArea.getText();
                if (message.equals("close")) {
                    closeChat = true;
                } else {
                    chat.sendMessage(message.toString());
                    MessageTextArea.setText("");
                    chatAreaText.append("\n" + this.username + ": " + message);
                    ChatTextArea.setText(chatAreaText.toString());
                }
 
 
          this.setVisible(true);
        } catch (XMPPException e) {
            System.out.println("Cannot find connections");
        }  finally {
          LoginPage.connection.disconnect();
        }
    }                                          
    /**
     * @param args the command line arguments
     */
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
            }
        });
    }
    // Variables declaration - do not modify
    private javax.swing.JTextArea ChatTextArea;
    private javax.swing.JTextArea MessageTextArea;
    private javax.swing.JScrollPane jScrollPane1;
    private javax.swing.JScrollPane jScrollPane2;
    private javax.swing.JButton sendButton;
    // End of variables declaration
}

Now when above LoginPage.java is made to run, this chatting thing works in steps mentioned in the starting of #-Link-Snipped-# post.

[ PS: Ah ! Damn tired even sleepy. Rest of the things I will post later. :sleeping: Good night ! Grant excuse if any mistakes made in all posts while typing]

Thanks ! Feel free to modify the code and making it better. Comments most welcome.

*Surprising * No comments yet. Anyways , xero Sir Please check if I am on right track or not. I guess if above thing is ok, then next thing we can do is

1. Designing of "MainWindow" -showing list of online members in green and offline if grey. Ading other icons and menu things. Everyone feel free to add ideas and icons or images for it.
2. Making chatting possible without using Spark at receiver's end. xero, Please give tips for this -how to proceed.

PS: All 3 java classes above are just roughly made so programming experts can find some of their time to optimize them to the best though they will go more changes in future.

Thanks ! 😀

i am doing second year computers
and all i could understand[things familiar to me] in first post was "Java" "Eclipse" "OO"
can someone tell me when i will be taught to make softwares of my own?
is eclipse used for the same?
i have written small small java programs for applets and addition multiplication etc in eclipse
but dont know wat exactly is required for making full softwares
will i be taught about it in my college? or it should be learned from net or reading certain books?

Ask your queries in separate thread. Don't SPAM this thread. Also SMS language is not allowed here.

Mods - I guess this post is not made for this thread. 😐

CEM you are going good 😀

With the existing progress have you tried chatting without Spark Client. You can proceed with the minimum requirements that you'll need to perform that operation. I've not looked at the new API specs provided, although in older versions it was bit sophisticated and it involved filtering at packet level which was pretty tedious. If possible try to go through the new API and search for other lesser sophisticated procedures to perform that operation.
I think we can ignore the status part right now and focus on providing a basic chat operation between two desktop agents ie. without Spark.

Let me know if you are stuck? If you want to know the details of the implementation that i just mentioned, its better to do over IM. So in that case PM me your IM id (yahoo, skype or gtalk) I'll share you the implementation and will give you a brief about it.

For a basic IM implementation it shouldn't take more than 5 classes 😀. So try to keep it as simple as possible. In swings try to ignore the AWT classes as much as possible, since these are platform specific implementations. Use the javax.swing package instead.

Till then, have fun !!

Hey I don't know how to proceed without using Spark ? 😔 That's why I asked you. Guidance Please if possible. I guess I have not made anything complicated till now. It is basic approach to keep every windo'w code separately though as soon as this project will progress , things may change accordingly.

Ok Man, I tried it bu just creating a replica of current project and then running two windows in my same system "without using Spark" anymore. The conversation as per me and current code, it went fine but I still feel some gotcha is there * scratching my head * Not sure 😕

See the conversations window at
Sender's end : "Admin"

[IMG]

Receiver's end : "CEMember"

[IMG]

Check, if this is correct way of doing or not? I guess now I need to get my hands good on "Swings" and more on Smack API. 😔
So I guess I should put a break for this here. What say xero ? Suggestions Please !

@xero-28ehVN • Jul 11, 2009

CEM, that's a fantastic job, well done 😀
By the way, what did you meant by gotcha in your last reply?

Although there might be a lot of issues still unresolved with the current code, however the current status is a marvelous check point.

Eg. In the current code, (btw, correct me if I'm wrong) if one user wants to chat with another user, both the users has to open the chat window. There are not listeners at either ends which would sense incoming message and pop up a window !

PS: Scratching your head is just gonna make you bald, so chill out mate you did good

I may not be available on Sunday. So i'll be back on this from Monday.

Happy weekend !

Hey ! Many thanks man 😀.
"gotcha" means mistakes that one is not awared of but know it is there.

Yes, you are right - I was thinking if I can do something like that opening a window at the receiver's end.I guess it would be something like handling offline message receiving thing[Not sure-Correct me if wrong]. As you mentioned adding listeners and stuff can do so, I need to look into it -how to do all that.

Thanks for the guidance ! 😁

I don't mean to derail discussions, but have any of you put into thought about socket programming with VB or C#? Creating messenger applications look a lot easy with that.. though with very basic capabilities. Useful for the programming newbies like me 😉

But, those who are deep into the Java and Smack in this thread are encouraged to continue development 😀

Is there anyone who would like to be work with me?
It would be great if previous team members come back

I will reply here soon once i set up environment required for this ..

Waiting for replies

The CE IM project will be closed. As Biggie as said we will be concentrating on smaller projects that should ship as soon as possible. Problem's that need solving and solutions that help.

@xero-28ehVN • Sep 17, 2012

so.. in continuation to what i've in mind this is time.. is a web page analogous to meebo.com, but more CE-centric, with messaging and lot of other features. I'll begin a new thread with some new name 😁

You know frankly, I don't want to see another messenger. We all are already so connected. Blackberry, facebook, SMS, Google Talk, Twitter, Google+, Facebook chat, yahoo, msn, blah blah blah the list goes on.

We should be working towards having face to face meetups in locations near us. Human interaction is slowly going away. It's still there in India but where I live, we are connected 24/6. Enough now.

#-Link-Snipped-#, while i appreciate your concern on 'yet another chat mechanism' & i sincerely hope you must have some plan in action for efficient vis-Ã -vis gatherings; my sole objective is learning using practical examples and we do have lot of enthusiasts who will be willing to learn from it. Even i'm learning technologies required and its fun 😀
Thus, lets not argue on whether we want it or not and focus on learning. I hope you understand my intent.

Hi xero, please proceed in starting a new thread for your ideas. I hope you are able to take the lead on it, get together a few CE members and steer the discussions 😀

Hi xhx, lets find a way to set up gatherings remotely (e.g via google hangouts), at least on some weekends or so..

from what i've experienced, from past projects, a long term project dies down in the middle, although significant learning happens, but still... its stuck in halfway. i'm wondering, how about a 24 hr code marathon? This makes it a ONE day exercise, full zeal, and final product in one day.. HEAD TO TOE. These days frameworks are stable and reliable to deliver products in crazy timelines. So how about such marathons?

#-Link-Snipped-#, what's your take?

@thebigk • Sep 26, 2012

We sure can host a marathon. I need to know the details and few volunteers who can take this forward. CE Messenger, however is a big product. Without deviating from the main topic; can we think of something smaller and 'achievable'?
