File Upload and Download utility using JSF

hello . . .

I wanted to upload and download file using JSF in my java web application.
I have tried using apache tomhawk but facing problem when try to deploy my application.
I am using Galssfish v3.Is there any problem with server or with jar file.
If i remove that tomhawk jar file than again my application run and deploy perfectly.

it shows error :- module has not been deployed, when i try to deploy application.

is there any other way to implement upload and download utility in jsf except apache tomhawk library ? ? ?

if any one having any sample code for this utility ?

I have also tried using request header.That runs perfectly in JSP but when i try it with jsf and i put enctype="" parameter to form than i am not able to call action on submit button.

any help ? ? ?
