Why new InitialContext remote is so slow ?

	hello , i ve tried to connect ejb's remotely by using ejbd protocol like;

           final Properties prop = new Properties( );
            prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.apache.openejb.client.RemoteInitialContextFactory");
            prop.put(Context.PROVIDER_URL, "ejbd://localhost:4201");

            final InitialContext c = new InitialContext(prop); // takes too much time like 5seconds on localhost connection , whats wrong ?



i didnt made profiling but its very interesting to connect localhost too much time.

If it's taking that long I suspect a network-lag issue.  Quick way to see what it might be doing is hit the client process with a 'kill -3' when it is doing that 5 second hang.  That should spit out what the client is doing.

Hey , my java clients connects to openejb directly.
But i think setting system property on clientside makes system vulnerability.
Any way to close setting properties ?
