Error going from Jboss 2.4.4 to 3.2.2

[cfoulkes]

Hi,

I have a simple test application (a client calling a stateful session ejb).

The code worked when deployed in Jboss 2.4.4, but when I run it under JBoss 3.2.2 it fails with the following exception:

javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:

The error occurs when processing the following code:



public static void main(String[] args) {
Hashtable env = new Hashtable();

env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL, "localhost:1099");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
try{
Context ctx = new InitialContext(env);
Object obj = ctx.lookup("StatefulSimple1");

it fails on the lookup.


If you can help explain what is going wrong I'd appreciate it.

Thanks

Are you using 3.2.2 client libs for your client?

Thanks a lot,

that was the problem,
I was still using the 2.4.4 client jars
