I have created a web service using Netbeans and have deployed it in jboss server. I also created a web service client in the same system. Now I need to change the web service url, which is http://localhost:8080/SGateway/ServiceGateway?wsdl, to [url=http://portaddr:8080/SGateway/ServiceGateway?wsdl. This port address has a proxy authentication also.
I tried editting the local wsdl in the web service client.But I get the below exception.

Exception in thread "main" com.sun.xml.internal.ws.client.ClientTransportExce ption: The server sent HTTP status code 503: Service Unavailable
