Hi

I am receiving the following exception

I get that exception on my client side test file, I retreiving the data across Java's RMI and if I run this exact "test" on the server side I retreive the data correctly. In my bean I have a Set which I have mapped in Hibernate too so that seems to be working fine too. Any advice?

Looks like you do not have the hibernate jar in the classpath on the client and are marshalling/unmarshalling a PersistentSet (hibernate specific class). Either add the jar to the classpath on the client or transform the PersistentSet to a Collection and then marshall it.

Yeah thanks that was the problem, I had added it any now its working fine, had to add some extra jars though, the commons-logging and cglib which solved everything.

Thanks anyway
