I am using Weblogic 12.2.1 and I added a JAX-WS client. It runs perfectly when run in eclipse but if I try to deploy the war file through the admin console I get: The url-pattern RegistrationService_V10 in web application webApp.war is mapped to multiple Servlets. The only place I could find a reference to that is the the com.oracle.webservices.wls.wls-soap-stack-impl package in a class called RegistrationServiceV10 which is annotaited as a webservice to RegistrationService_V10 but that is the only place I could find a reference to it, not mapped in my web.xml so where is the multiple servlet mapping coming from.
