Thank you for your answer.

As I guess my customer will not agree seing JBoss specific annotations on its EJB3, I wonder if it may be possible to add annotations at deployment thanks to an "AOP domain" as described here: http://docs.jboss.org/ejb3/docs/reference/1.0.7/html/SessionBean_and_MDB_configuration.html

By the way, I will give a try to JBoss 7 too.

Hello,

I need some help to get my EJB3 published over IIOP.

My interface Service extends EJBObject.

I have added ServiceHome which extends EJBHome

My bean ServiceBean  now have to implement 5 methods I do not know how to write them:

- EJBHome getEJBHome()

- Handle getHandle()

- Object getPrimaryKey()

- boolean isIdentical(EJBObject arg0)

- void remove()

Am I on the right path ? How to implement these five methods ?

To expose bean v3 over iiop in jboss 5 you need the right profile (look @ slimming jboss to know how to enable corba/iiop naming service etc...i remember "all" profile has corba enabled by default)

and ejb/interfaces like these:

1)

public interface MyRemote extends EJBObject {

String hello(String name) throws RemoteException;

}

2)

public interface MyRemoteHome extends javax.ejb.EJBHome {

MyRemote create() throws javax.ejb.CreateException, java.rmi.RemoteException

}

3)

@Stateless

@RemoteHome(MyRemoteHome.class)

@IIOP(interfaceRepositorySupported=false)

public class MySessionBean {

public String hello(String name) {

System.out.println("hello called for name: " + name);

return "Hello " + name;

}

}

then in jmx-console -> corbaNamingservice you should find the right name to use.

Note: for @Clustered EJB --> no container failover and load-balancing if invoked via IIOP

Hope this help,

bye

With @Stateless, @RemoteHome, @Remote and @IIOP annotations, my EJB3 no longer deploys in JBoss 6.1:

Have you got any idea about the mistake I did ? Do you recommend me to remove ejb-jar.xml and jboss.xml ?

My ejb-jar.xml

Many thanks for your help

If you are talking about JBoss EAP 6 I think you should have a subscription, in that case you can ask to RH Support.

As I already mentioned, I tried it in AS 5 (with EJB and interfaces into an EAR archive).

I think you don't need descriptors..

At any rate my ejb-jar.xml was:

<?xml version="1.0" encoding="UTF-8"?>

<ejb-jar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:ejb="http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd" version="3.0">

  <display-name>MySampleSession</display-name>

  <ejb-client-jar>MySessionClient.jar</ejb-client-jar>

</ejb-jar>

OK. I am using JBoss AS 6.1. "EAP 6" is build over JBoss AS 7...

There were errors in my Remote interface JBoss 6.1 does not report properly where JBoss AS 7.1 did.

So now my EJB3 deploys in JBoss AS 7.1

But I still completely obscure "error due to the following reason(s): java.lang.ClassNotFoundException: Null class name" in JBoss AS 6.1
