I'm using IBM RAD v7 which is based on Eclipse and I've got a NullPointerException in a compiled JSP that I want to troubleshoot. So I wonder where websphere / Eclipse (IBM RAD) stores the source for the compiled JSP that the error message is referring to?
Locate your runtime directory. If this is an embedded runtime, it'll be something like:
/opt/IBM/SDP/runtimes/basev7
The servlets are usually compiled lazily to the profile's temp directory. This path will be of the form:
/profiles/profileName/temp/nodeName/serverName
The profile, node and server name are configuration dependent. Subdirectories will follow your EAR/WAR hierarchies.
