How to trace and debug Java in JSP

843785Aug 12 2008 — edited Aug 14 2008
Hello.

I've been getting this java.lang.NullPointerException error on my JSP pages. I try to search for the null value, but didn't find it. Is there any tool/debugger that can be used to trace the null variable? Well, if that is even possible.

Thanks in advance.
