I am using spring rmi (version 3.2.1) and trying to connect to a remote rmiregistry ("remote" in the sense that it is not embedded, the rmi registry runs on the same node but as a different process).
I get this error when trying to start rmi server:
java.rmi.ServerException: RemoteException occurred in server thread; nested exception is:
java.rmi.UnmarshalException: error unmarshalling arguments; nested exception is:

The rmi registry can't access to spring rmi classes. (RmiInvocationHandler).
You have two options:
Enable dynamic class downloading using the codebase property: see: http://docs.oracle.com/javase/6/docs/technotes/guides/rmi/codebase.html
Give access using CLASSPATH: Just allow the rmi registry to use all classes that it will need at startup. For example:
export CLASSPATH=lib/spring-core-XXX.RELEASE.jar:lib/spring-context-XXX.RELEASE.jar:lib/your-other-classes-used-in-rmi.jar
