1. You can figure out which files are which using "ls -l". Files in the same package will likely have the same dates; older files are from older libraries.
2. Q: did you look for GJC (a suggestion in my first post)?
Q: If you found it, did you uninstall it?
3. MOST IMPORTANT:
It sounds like some jsp's and/or servlets are working, and some aren't.
Q: Could you please be as specific as possible about what's working vs what's not? Post code, if at all possible.
Thank you in advance .. PSM
Please specify, too:
* Your distro and version
* Whether you got your Tomcat 5.5.28 from your distro's package manager, or whether you built it yourself
It couldn't hurt to check your Tomcat log, if you haven't already. Here's an example from mine:
less catalina.out =>
Using CATALINA_BASE: /usr/share/tomcat5
Using CATALINA_HOME: /usr/share/tomcat5
Using CATALINA_TMPDIR: /usr/share/tomcat5/temp
INFO: Find registry server-registry.xml at classpath resource
