Classloading; that simple error was just a beginning

Recently found myself in class-loading issues. Came across two nice tools to analyze the problem.

1. One is generic tool that can be used with any app server and also standalone programs: http://blog.jhades.org/classnotfoundexception-jhades-jar-hell-made-easy/
2. Second is weblogic specific, but good thing is you don't need to add any new jar or listener, its available for any application deployed + it also tells about the possible solution for the conflicts:Classloader Analysis Tool (CAT)

Enjoy .... (putting conflicting jars in the classpath and then solving the issues 1 day before the release *_^)
