Jax-RS url-pattern causes 404 error

Question

I am running JBOSS 6.4 EAP in eclipse oxygen.

I have a simple and working webservice that just returns is alive.

When I configure the url-pattern as " /* " it is executed as expected. When I put a more substantial pattern "/rws/*" in the url-pattern I get 404

My URL is localhost:8080/mesh/rws/menu/isAlive

failing web.xml There is no corresponding servlet block for this servlet

<servlet-mapping>
    <servlet-name>javax.ws.rs.core.Application</servlet-name>
    <url-pattern>/rws/*</url-pattern>
</servlet-mapping>

Servlet Class

@Path("/rws/menu")
public class MenuService
{
    @GET
    @Path("/isAlive")
    public Response isAlive()
    {
        return Response.ok("I am alive").build();
    }
}

Error from Server

JBWEB000065: HTTP Status 404 - RESTEASY001185: Could not find resource for relative : /menu/isAlive of full path: http://localhost:8080/mesh/rws/menu/isAlive

Context param I have tried adding the context param to web.xml as suggested in various places on line, but it seems already set and I am not sure how to over ride.

<context-param>
    <param-name>resteasy.servlet.mapping.prefix</param-name>
    <param-value>/rws</param-value>
</context-param >

yields error:

ERROR [org.apache.catalina.core] (ServerService Thread Pool -- 64) JBWEB001097: Error starting context /mesh: java.lang.IllegalArgumentException: JBWEB000280: Duplicate context initialization parameter resteasy.servlet.mapping.prefix

When you have /rws/* in the url-pattern, you're not supposed to put /rws in the @Path also. If you do this, then the url would be /rws/rws. The url-pattern is the prefix for the entire application. So just remove the /rws from the @Path.
