I have small standalone java app that invokes a method on an EJB. It worked fine under jboss/tomcat but under jboss 3.02 it fails on lookup with the error below. Here is my (simple) call:

InitialContext jndiContext = new InitialContext();
Object ref = jndiContext.lookup("CIS/SearchManager");

Here's the error:

javax.naming.CommunicationException. Root exception is java.rmi.UnmarshalExcept
ion: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: org.jnp.interfaces.MarshalledValuePair
(no security manager: RMI class loader disabled)

I have very little idea what this means after spending all day on it. Does anyone have any ideas?

Thanks,
Alan
