Sorry to disturb you...
I am beginner of jboss, I use JBoss 4.0 (default server configuration) and I cannot find any useful document to solve my problem...
It seems there are lot of problems with ConnectionFactory binding... and UnmarshalException
I use a basic tutorial ... Please tell what is wrong ...

thank you very much ...

Here my code

private InitialContext getContext() throws NamingException {

Hashtable props = new Hashtable();
props.put(InitialContext.INITIAL_CONTEXT_FACTORY,
 "org.jnp.interfaces.NamingContextFactory");

props.put(InitialContext.PROVIDER_URL, "jnp://127.0.0.1:1099");

props.put(props.put(InitialContext.URL_PKG_PREFIXES,
 "org.jboss.naming:org.jnp.interfaces" );


InitialContext initialContext = new InitialContext(props);
return initialContext;
}
...

private void executeMdb() {

try {
 InitialContext ctx = getContext();
 System.out.println("executeMdb: InitialContext OK...");
 System.out.println("executeMdb: InitialContext : " + ctx );

 // just to see all context names
 NamingEnumeration enum = ctx.list(ctx.getNameInNamespace());
 while (enum.hasMore()){
 System.out.println("Naming Context " + enum.next());
 }

 QueueConnectionFactory factory = (QueueConnectionFactory)
 ctx.lookup("ConnectionFactory");
 System.out.println("executeMdb: lookup ConnectionFactory OK...");

...

The output is something like that:

javax.naming.CommunicationException [Root exception is java.rmi.UnmarshalException: error unmarshalling return; nested exception is:
java.lang.ClassNotFoundException: org.jboss.mq.referenceable.ObjectRefAddr (no security manager: RMI class loader disabled)]
