Very strange since I dont think Im doing anything wrong. Simply adding methods in ejb and Webservice. It has happend before and the workaround was to create a duplicate Web service, copy all over and re setup the service. then re add to the enterprise application and redeploy. Would be nice If I can find the solution to what Im doing wrong instead of having to recreate the WS. Thanks for the time. Hope to hear some possibly solutions/causes.
