Please help me to resolve this. Server - JBoss 4.2, I have two nodes created in the server that is nodeA and nodeB. nodeA deploys the service. This web service is made available to nodeB. During nodeA start up, i see webservice being deployed and also i see wsdl is generated and published. I can access the webservice via browser. I can see wsdl file in browser. Problems comes when i try to access webservice from nodeB. I get the following exception : 10:23:06,528 ERROR [STDERR] javax.xml.ws.WebServiceException: Cannot create proxy 10:23:06,530 ERROR [STDERR]     at
