I am not able to set a breakpoint in a jsp. "Add/Remove Breakpoint " option is enabeled under "Run" menu in the debug perspective. But nothing happens when I try to set the breakpoint for a java scriplet in a JSP. Please note that I am able to set breakpoint and debug my struts action handlers just fine (which is awesome !). Some more facts:

OS Platform: Win 2k SP3
Eclipse Platform: Version 2.1.1
MyEclipse Enterprise Workbeanch: Version 2.5.1
Application Server: Weblogic 7.0
Weblogic Server JDK version: 1.4.1_03
Java Compiler compliance level in project properties: 1.4

Can you please help ? Thanks !

Well, my first guess is that you didn't tell WebLogic that you'd be debugging JSP's, as specified in this post from the documentation forum:

Thanks for the suggestion. Actually, I had added weblogic.xml with debug parameter set to true.

I can debug JSP now. It turned out to be a silly user error. "Add Remove Breakpoint" under "Run" menu did not set a breakpoint for me. But double clicking on the left margin of the line of code did set the breakpoint.

Thanks again, Shah
