I'm getting the following error when I try to access an ejb from a jsp page. I have read several interpretations of the LinkageError. The gist of the cause seems to be multiple, non-identical versions of a class in the classpath. I am most interested to know how to figure out specifically what class is causing the error and why. How do I isolate the problem and fix it?

java.lang.LinkageError: loader constraints violated when linking org/cayambe/core/CategoryVO class
