[jboss-user] [Beginners Corner] - Problem with socket connection to an EJB

[Andrechan]

I'm using Jboss v4.2
I have an application that generates threads who do a remote call to a session bean in a method like this
public void doWork()
  |     {
  |        
  |         Properties p = new Properties( );
  |         p.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
  |         p.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
  |         p.put(Context.PROVIDER_URL,"jnp://"+ip+":1099");
  |        
  |         Context context;
  |         try{
  |             context = new InitialContext(p);
  |             NavSenderRemote beanRemote = (NavSenderRemote) context.lookup("WSGeoEAR/NavSenderBean/remote");
  |            
  |             Random r = new Random();
  |             int lat=r.nextInt(100);
  |             int lon= r.nextInt(100);
  |            
  |             beanRemote.setPosition(idUtente, lat, lon);
  |            
  |         }catch (NamingException e){
  |             e.printStackTrace();
  |         }

This application works if I run it on the same computer but if I run it on another computer it gives this exception on the client side:

I have already checked that
-Jboss runs with -b 0.0.0.0

-the ip is correct 
any ideas?
