Thank you. I think OpenLaszol doesn´t support RPC-Literal, but I will try. I now tried to change the WS to Document-Literal. Deploying I get the Error ERROR [MainDeployer] Could not create deployment: file:/C:/bin/jboss-4.0.4.GA_1/server/default/tmp/deploy/tmp51974ws1.ear-contents/beans. | jar | org.jboss.ws.WSException: Attempt to map multiple operation inputs to: {http://server/jaws}int Any Ideas?
