i thought it was activation/passivation issue to start with but after
putting some tracing code in i saw that none of the beans had been
passivated. then i noticed in my ejb-jar.xml that the KnowledgeBaseMgr bean
was declared as Stateful so i changed it to Stateless and everything worked
fine (no barfing after FinderException). great except i need
KnowledgeBaseMgr to stateful. ssssooooo, in the stateful case, why would
jboss be looking be looking for a passivated instance of KnowledgeBaseMgr
after a FinderException, when the bean hadn't been passivated in the first
place? or maybe i'm still doin something stupid...
