I have a sessionless ejb to call another sessionless ejb. When the two ejb are deployed in the same machine (jboss 4.0.4.GA), the call are fine, but , after I deploy in two different machine, I can't call it any more. The IP address of 192.168.2.191, is where the 2nd Ejb deployed The way I call another ejb from one ejb is as follow: //look up jndi in payment server machine Hashtable<String,String> env = new Hashtable<String,String>(); env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory" ); env.put(Context.PROVIDER_URL, "jnp://192.168.2.191:1099"); env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" ); Context ctx = new InitialContext(env); //Object obj = ctx.lookup("java:/comp/env/ejb/PaymentEJB"); Object obj = ctx.lookup("ejb/PaymentEJB"); PaymentHome home = (PaymentHome)javax.rmi.PortableRemoteObject.narrow(obj,PaymentHome.class); Payment payment = home.create(); resp = (HashMap<String,String>)payment.deposit(req); Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3969847#...
