I have a webapp, deployed as a war, which exposed a Web Service implementing jaxws standard. A requirement for my webapp is deploy on multiple AS (Tomcat, JBoss and WAS). In my war i have jax-ws ri distribution (into WEB-INF/lib). web.xml contains the jaxws listener: <listener-class>com.sun.xml.ws.transport.http.servlet.WSServletContextListener</listener-class> When i deploy my webapp on JBOSS (v.4.2.3.GA) i have the following error: 2009-05-12 15:15:38,608 ERROR [STDERR] 12-mag-2009 15.15.38 com.sun.xml.ws.transport.http.servlet.WSServletContextListener contextInitialized INFO: WSSERVLET12: JAX-WS context listener initializing 2009-05-12 15:15:44,311 ERROR [STDERR] 12-mag-2009 15.15.44 com.sun.xml.ws.transport.http.servlet.WSServletDelegate INFO: WSSERVLET14: JAX-WS servlet initializing If I remove the Ws Listener from web.xml the errror disappears, but the war does not deploy on Tomcat Any suggestion?
