Sanjay,
The JSP is just displaying your data. You say that that is working
fine. When the user changes the data and submits the form, your servlet
then needs to process the form data and update the bean. The JSP does not
update the bean.
Regards,
Richard
P.S. If you think that a topic has been beaten to death on a forum, it is
better to look up the problem in the forum archives first rather than post
it to the forum again.
