    Connection time out

    Ruben Verlinden Newbie

      I have problems getting an RMI connection to a JBoss server over the public internet. Using exactly the same code and server configuration it works flawlessly from within the same LAN (public IP's 134.184.xxx.xxx). The exception thrown is displayed at the bottom of this message.

      I know for sure the server isn't firewalled so that can't be the reason.

      Below you can find the code for getting the EJBHome object and initialising the context and the thrown Exception.

      Any pointers to a possible solution are very welcome.

      thx,
      Ruben


      Initial Context code (In Eclipse plugin) :

      private static final String IntialContextNamingFactory = "org.jnp.interfaces.NamingContextFactory";
       private static final String NamingProviderURL = "134.184.xxx.xxx";
      
       /**
       * Returns the initial jndi context.
       * The parameters are hard coded into this function for the moment and some
       * ClassLoader tricks are necessary to intialise the JNDI environment.
       *
       * @return Context
       * @throws NamingException
       */
       static public Context getInitialContext()
       throws NamingException {
       InitialContext context;
      
       // Save the current ClassLoader for reloading it after the JNDI
       // environment is intialised.
       ClassLoader tmp = Thread.currentThread().getContextClassLoader();
      
       // get the plugin ClassLoader to initialise the JNDI environment
       Thread.currentThread().setContextClassLoader(pluginType.getClassLoader());
      
       // The context properties
       Properties p = new Properties();
       p.setProperty("java.naming.factory.initial", IntialContextNamingFactory);
       p.setProperty("java.naming.provider.url", NamingProviderURL);
      
       // Initialise the JNDI environment
       context = new InitialContext(p);
      
       // Reinstate the system ClassLoader
       Thread.currentThread().setContextClassLoader(tmp);
      
       return context;
       }
      


      Get EJBHome :
       /**
       * Retrieves the Home interface of the EJB and puts the HomeHandle in the cache
       *
       * @param jndiName : the service name, e.g. OntoBaseFacadeEJBHome
       * @param type : class of the HomeRemote interface, e.g.OntoBaseFacadeEJBHomeRemote.class
       * @throws ServiceLocatorException
       */
       private void getJndiService(String jndiName, Class type)
       throws ServiceLocatorException{
       // Access to the shared Context as well as the additions to the
       // cache must be synchronised.
       synchronized(this) {
       try {
       // Lookup the JNDI name and retrieve the EJBHome object
       Object rRef = context.lookup(jndiName);
       EJBHome home = (EJBHome)PortableRemoteObject.narrow(rRef, type);
      
       // Put the EJBHome object in the cache
       cache.put(jndiName, home);
      
       // Code when using HomeHandles in the cache instead of EJBHome objects
       // Put the HomeHandle of the EJBHome object in the cache
       //cache.put(jndiName, home.getHomeHandle());
      
       } catch(NamingException ne) {
       System.out.println("Unable to find JNDI service. " + ne.toString());
       throw new ServiceLocatorException("Unable to find JNDI service",ne);
       }
       // This Exception is only thrown when using HomeHandles in the cache instead of
       // EJBHome objects
       /*catch(RemoteException re){
       System.out.println("Remote Exception in ServiceLocatorEJB. " + re.toString());
       throw new ServiceLocatorException("Remote Exception in ServiceLocatorEJB",re);
       }*/
       }
       }
