I found some simple example which could be easier to test:
Hashtable<String, String> props = new Hashtable<String, String>();
props.put(InitialContext.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(InitialContext.PROVIDER_URL,"jnp://" + urlRemoteMachine);
props.put(InitialContext.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
props.put("jnp.timeout", "1000");
props.put("jnp.sotimeout", "1000");
InitialContext initialContext = new InitialContext(props);
MyBeanRemote remote = (MyBeanRemote) initialContext.lookup("MyBean/remote");
System.in.read();
System.out.println("Start");
System.out.println(remote.someMethod());
System.out.println("Stop");
When server is down lookup fails after jnp.timeout, but when I stop program on read() and then turn off remote server remote.someMethod() whaits a long time before returning with Exception:
Exception in thread "Main Thread" org.jboss.remoting.CannotConnectException: Can not get connection to server. Problem establishing socket connection.
