JBoss WS (the web service stack that GateIn uses), you need to pay attention to details of updating the port and host name used in WSDL. See the JBoss WS user guide on that subject for more details.

Of course, if you have modified the host name and port on which your server runs, you will need to update the configuration for the consumer used to consume GateIn's 'self' producer. Please refer to the Section 4.3.2, “UI Extensions ” to learn how to do so.
