Fail to lookup EJB3 as JBoss return internal IP
dinnychk Jun 30, 2007 1:28 AMHi,
I wrote a HelloWorld EJB 3 and HelloClient to test remote access JBoss server, but failed as IP changed by firewall.
The server is linux and using JBoss 4.0.4.GA with jdk1.5.0_09.
I tried to start JBoss with "run.sh -c default -b <external IP>" , jboss cannot start with error :
2007-06-30 21:16:12,840 ERROR [org.jboss.remoting.transport.socket.SocketServerInvoker] Error starting ServerSocket. Bind port: 3873, bind address: /202.155.230.102
