Richard, Thanks for the quick response. I did lookup the archive at JDC, but did not find an exact match. Actually I did find one exact posting without any response to it.
You said JSP does not update the bean. Is that my JSP code or are you saying JSP in general "can not" update a bean. How does a servlet process form data ? Is it the request.getparameter() method that you are referring to ? You will have to forgive my ignorance, my exposure to JSP/Servlet is 1 week old. Thanks again Sanjay Jain -----Original Message----- From: Richard Yee [mailto:[EMAIL PROTECTED]] Sent: Monday, December 03, 2001 5:07 PM To: [EMAIL PROTECTED] Subject: Re: passing bean from JSP to servlet 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.
