JAX-WS Web service on Tomcat without sun-jaxws.xml

Question

I am trying to minimize required configuration while deploying JAX-WS-based Web service on Tomcat. With the introduction of Servlet 3.0 (supported by Tomcat 7+), web.xml

Answer 1

You have to publish the web service. You can implement a ServletContextListener and publish the endpoint:

@javax.servlet.annotation.WebListener 
public class AppServletContextListener implements javax.servlet.ServletContextListener {

    public void contextInitialized(ServletContextEvent sce) { 
        Endpoint.publish("{protocol}://{host}:{port}/{context}/{wsName}", new MyHelloWorldWSImpl());
    } 

    public void contextDestroyed(ServletContextEvent sce) { 
        .... 
    }
}

sun-jaxws.xml is not mandatory by specs...If you note, for example, glassfish (metro) makes it optional. Also, if you expose a EJB 3.1 as webservice (with jaxws) you can see no sun-jaxws.xml file in the generated build.
