Actually i am working on a discussion forum using jsp but coming across a problem because i don't know the tag of how to change the content of jsp page dynamically. The actual problem is i have divided particular topics according to forums like the same way this site is using.I was very impressed with the way this forum is working. I have kind request to the moderators of this site as well as other people if they can provide any clues to me. Thank you.
As far as I can tell. This site uses a non-Java cgi solution for forums. Ultimate BB is a perl program with no database backend (poor search functions). Maybe we should consider using a Java based discussion forum such as Jive. Or,maybe JavaRanch users can wrote our own BB software from scratch.
Changing the content of JSP pages dynamically is typically done with custom taglibs or "JavaBean" helper classes - as opposed to coding lots of logic in the JSP itself. Take a look at the source of one of these pages to see how hidden variables in a form are used to provide parameters in the request that identify the forum, etc. Bill
