    Remoting works locally, but not remotely

    Roman van der Krogt Newbie

      Hi all,

       

      I ran into some issue with moving our application from JBoss 6 to 7 (7.1.1.Final), so I decided to focus on getting some of the quickstarts to work first, and learn from that. I'm stuck now, however, on the remoting quickstart (ejb-remote). I have successfully deployed it, and the client works from the local machine. However,  I'm getting the following exceptions when I try to run the client from a different machine:

      Using tcpdump, I can see the client and server exchanging messages, so I'm sure there is no issue with the connection itself.

       

      The code that performs the lookup is as follows:

       

      private static RemoteCounter lookupRemoteStatefulCounter() throws NamingException {

          final Hashtable jndiProperties = new Hashtable();

          jndiProperties.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");

          jndiProperties.put(Context.SECURITY_PRINCIPAL, "test");

          jndiProperties.put(Context.SECURITY_CREDENTIALS, "1234");

          final Context context = new InitialContext(jndiProperties);

          return (RemoteCounter) context.lookup("ejb:JBoss7Test/JBoss7TestEJB//CounterBean!" + RemoteCounter.class.getName()+"?stateful");

      }

       

      The lines in bold are added by me, and correspond to the user/pass that was created for the ApplicationRealm. Otherwise, the code is as in the quickstart, except that I removed the comments here for brevity, and changed the id to look up

       

      My jboss-ejb-client.properties looks as follows. (Note that in the current form it also lists the user and pass. I've tried specifying these only in the code, only in the properties file, in both and in neither as well, but always with the same outcome).

       

      remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false

       

      remote.connections=default

       

      remote.connection.default.host=XXXXXXXXXXXXXXXXXXXXXX

      remote.connection.default.port=4447

      remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false

       

      remote.connection.username=test

      remote.connection.password=1234

       

      As I said, it all works brilliantly locally, but not from a different server. I must be missing some config option somewhere. Any and all pointers welcome.

       

      Thanks,

        Roman.
