[chogori_]

i've created two entity beans. the first one contains the relation field. when i run the system assignments are properly done. but after i try to get back the bean which is in the relation an error occur :

java.rmi.ServerException: null; CausedByException is: $Proxy173; nested exception is: javax.ejb.EJBException: null; CausedByException is: $Proxy173

i don't what this mean. can anybody help me.

What version of JBoss are you using? What is the serverside exception printed in the server.log file?
