    Remote EJB Context Initialization fails

    Maximilian Hillebrand Newbie

      Hello all,

      i have a backend server application which is running on the jboss-7.1.1 server. This application consists of several statless beans.

      First the frontend and backend run on the same server and it works. Now i want to seperate the two parts from each other and it get following exception when im trying to get initialContext:

      With telnet i can connect to the backend, but i have to start the jboss server with: standalone.bat -b "0.0.0.0"

      The following code shows the initialization of the context :

       

          /**

           * getting intialcontext for jb

           * @return

           */

                @SuppressWarnings("unchecked")

                private InitialContext getInitialContext() {

                                      @SuppressWarnings("rawtypes")

                                      Hashtable props = new Hashtable();

                                     props.put(Context.INITIAL_CONTEXT_FACTORY,

                                                          org.jboss.naming.remote.client.InitialContextFactory.class.getName());  

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

                                     props.put("jboss.naming.client.ejb.context", true);  

                                     props.put(Context.PROVIDER_URL, "remote://x.x.x.x:4447");

       

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

                                     props.put(Context.SECURITY_CREDENTIALS, "123");

                                     try {

                                               return new InitialContext(props);

                                    } catch (NamingException e) {

                                              e.printStackTrace();

                                              return null;

                                    }

                }

       

      The user and password are already created on the jboss server.
