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 :
