    javax.xml.ws.WebServiceException: Cannot create proxy

    syed.azharsultan Newbie

      Hi Friends,

       

      Am facing an exception while invoking  webservice. 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 :
