TO CLARIFY: the exception javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory] is occurring on the server, not on the client. I can watch it happen using IDEA remote debugging on the JBoss instance. I'm wondering if there is a class loader issue, since the RMI access takes a much different code path than the JMX console does.
