Please describe your problem a bit more detailed. What are your current knowledge of Java, Should the forum be viewed in a browser or in a standalone app? What have you accomplished so far?

Then you may get some help here.

I'm developing a web-based DSS using Java Server Pages whereby I need to allow the creation of forums.

The problem is that i've always used java in eclipse. Never used JSP before so I'm having problems with the language.

By the way, I've created forums in php before but not being able to do so in JSP.
