Pardon a question from a newbie to the list. I'm trying to test a Message Driven Bean using JBoss 2.4 beta, but am missing a jar file. (Well, 2.4 is missing a couple jar files, but I copied them from 2.2.2.) Specifically, the test case is failing with a NoClassDefFoundError looking for EDU/oswego/cs/dl/util/concurrent/ThreadFactoryUser. Can somebody point me to where I might find the jar file containing that class, or am I just too far ahead of the implementation of MDB? Thanks for any info.
