Doubt in java programming...?

hello friends,
check these codes..
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class pp extends Applet implements ActionListener
{
    TextField t;
      Button    b;
    public void init()     
    {
            setLayout(new FlowLayout());
           t= new TextField(40 );
            b = new Button("Send");
        b.addActionListener(this);
            add(t);
            add(b);
      }
     public void actionPerformed(ActionEvent e) 
    {
               String str=t.getText();
        dc a2 =(dc)getAppletContext().getApplet("a2");
               if ( a2 != null ) 
        {
                  a2.append(str);
               }
               else 
        {
                  System.out.println("Applet not found?");
               }
         }
}
and the 2nd applet code goes here...
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
/**/
public class dc extends Applet
{
    TextArea t;
    public void init()
    {
        setLayout(new FlowLayout());
        t=new TextArea(40,50);
        add(t);
    }
    public void append(String msg)
    {
        t.setText(msg);
    }
}
here goes the html codes...
Don't know why it doesn't works.

    Hi Mohit,

    I checked your code and found that in pp.java at line # 20
    dc a2 =(dc)getAppletContext().getApplet("a2");
    You are trying to call an applet with name as "a2" as per the AppletContext.getApplet method specifications but I checked in your HTML page, there is no name specified. You are supposed to specify the name of the "dc" applet as "a2" in the HTML code. So now your new HTML code should be
    Now run, it will work. Let me know if any questions.
