Yes, that is exactly what I have.

Below are logs from EJB server showing successful deployment, could verify same in JNDIView MBean

When I do lookup on client side, i get object of CORBAObjectImpl but narrow returns null.
I also tried doing lookup from java main test method and also get null after doing PortableRemoteObject.narrow()


I see 4-5 posts on this very issue but nowhere has anymore mentioned the resolution which seems suprising to me.
Do we need to decorate EJB client with some JBoss descriptor file or setup some security or enable dynamic proxy?


Is there a workaround to generate static stubs for RMI/IIOP somehow because when I deploy my Websphere client jar (with stubs in it), narrow works fine and gives me Home reference back.
