[jboss-user] [JNDI/Naming/Network] - Re: RMI-IIOP
Ok, the status so far:
My C#-Client can lookup the SessionBeans and invoke them.
But I just don't get any Java-Client to retrieve any SessionBean.
Nevertheless, JNDIView states all EJBs are bound to right JNDI-Names.
Now I'm already getting a reference at the clientside, but narrowing causes a
NullPointerException:

I've tried all combinations of Properties (INITIAL_CONTEXT_FACTORY, PROVIDER_URL,
URL_PKG_PREFIXES) with corresponding values and I think i have included all
clientside-necessary JARs (jbossall-client.jar etc).
WHAT AM I DOING WRONG?
I've searched the web and found all just the same but no solution works for me.
Please tell me, which jar's to be included (serverside/clientside) or specific
configurations which might cause problems... :-/
