Remoting JBoss AS 7 to AS 4 and vice versa

Is it possible to remotely access an EJB on a JBoss AS 4 from a JBoss AS 7 and vice versa (using EJB3)?

If so, how can I do it?

I am looking for any information about remoting between different JBoss Versions. There must be something on the web, but I'm struggling on finding the right search terms.

Solution

  • It's possible.

    You have to create the remote interface and the bean on JBoss A4.

    @javax.ejb.Remote
public interface JBossFourRemote{
    int doSomething();
}

@javax.ejb.Stateless
public JBossFourBean implements JBossFourRemote{
    public int doSomething(){
        return 1;
    }
}

    Deploy that, and then call the bean from the JBoss AS 7 client as follows.

    public void someJBossSevenMethod(String args[]){
    JBossFourRemote bean = (JBossFourRemote)new InitialContext().lookup("java:global/app/module/JBossFourBean!JBossFourRemote");
    bean.doSomething();
}
