we are using replica-aware clustered EJBs. We are curreclty experimenting with custom load balancing mechanism offered by weblogic via callRouter interface. However we experimenced some kind of wierdnes regarding JNDI tree corruption. We would like to get some visibility (tracability/debug) into weblogic routing/loadbalancing mechanism. I tried DebugRouting from servers/debug - default settings but I didn't see what I would expect. May be I was looking into the wrong location (server logs).
