[jboss-user] [JBossCache] - PojoCache can't find classloader

[chip_schoch]

I have a two server cluster and am trying to cache a sessionData object using PojoCache.  When I initially start the app and try it I see the exception listed at the bottom.

I am kind of confused about what I am supposed to do.  I am using jdk5.0, Cache 1.4.1 SP2.  I don't get any exception when I put the object in a single server cache, but when it goes into the cluster it throws.  I have read and tries to follow all the instructions I could find but none seems to go flawlessly.  For instance, it is not clear that to me that if I am annotating my classes that I still need to use the aopc precompiler to make this work, or is it just supposed to work?
