[jboss-user] [EJB 3.0] - Fail to lookup EJB3 as JBoss return internal IP

[dinnychk]

Hi,

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 :
