pls help - calling EJB over IIOP

[sagimann]

Hi,

I'm new to Jboss. I've been working with SJSAS up until now, and I'm pulling my hair out on this one:

I'm trying to simply configure my jboss-web.xml so that my servlet could call an EJB 3.0 stateless session bean. Both web app and ejb are running on JBoss 4.2.2GA ('all' configuration) with JDK 1.5, but not on the same host. For testing, however, I run them both on the same host (localhost).

My EJB 3.0 is a simple session bean called ejbtest.HelloBean with a remote interface ejbtest.HelloRemote. I've verified that, by default, it is registered in JNDI under:
(SJSAS): ejbtest.HelloRemote
(Jboss): ejbtest/HelloBean/remote

In SJSAS, in order to call the EJB from my web app, I would configure my web app's sun-web.xml like this:

<ejb-ref>
 <ejb-ref-name>hello</ejb-ref-name>
 <jndi-name>corbaname:iiop:localhost:3700#ejbtest.HelloBean</jndi-name>
</ejb-ref>

I combed the internet for the JBoss equivalent, and I'm still unable to create a valid jboss-web.xml file!!!
I already tried the following:

1. Override the default invoker proxy in my EJB's jboss.xml file, i.e.:

 <invoker-bindings>
 <invoker>
 <invoker-proxy-binding-name>iiop</invoker-proxy-binding-name>
 <jndi-name>ejbtest/HelloBean/remote</jndi-name>
 </invoker>
 </invoker-bindings>

2. use various jndi-name tags in jboss-web.xml, and get various errors:

jnp://localhost:1099/ejbtest/HelloBean

java.lang.ClassCastException: org.jnp.interfaces.NamingContext

No dice.
I am NOT looking for a solution that involves writing JBoss-specific code in my web app, cuz it won't be portable.

Any ideas??? It should not be that complex AFAIK.
thanks in advance...
