I now (just) have a simple EJB client/server system that works fine on a
single machine.
But I am getting exceptions when looking up the Bean if the client and
server are on separate
machines. Code and jar file usage
(jnpserver.jar;ejb.jar;jboss-client.jar;jndi.jar) are the same on
all clients. I get different tracebacks from different client machines.
>From a Linux machine with java 1.2.2 I get:
Exception in thread "main" javax.naming.CommunicationException. Root
exception is java.rmi.UnmarshalException: error unmarshalling return;
nested exception is:
