Resource Injection

[Sam Merrell]

I have been looking everywhere and can't find much information on how
resource injection works for JAX-WS 2.0 web services.  Any pointers in the
right direction on how to use the @WebServiceRef or @Resource annotation
would be great.

I have a Java client that I'm trying to get resource injection for but I
keep getting a NullPointerException.

Here is the client:

package aTest.client;

import java.io.IOException;

import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.xml.ws.WebServiceRef;

import aTest.service.EJBHelloService;
import aTest.service.EJBHello;

/**

 */
public class TestEJBHello extends HttpServlet implements Servlet {

    @WebServiceRef( wsdlLocation = "
http://localhost:8080/EJBHello/EJBHelloService?wsdl"; )
    static EJBHelloService myService;

    public TestEJBHello() {
        super();
    }

    @Override
    protected void service( HttpServletRequest req, HttpServletResponse resp
)
            throws ServletException, IOException {
        System.out.println( "Service Method..." );
        resp.getWriter().println( "Getting EJBHelloPort..." );
        EJBHello port = myService.getEJBHelloPort();
        String msg = port.sayHello( "Sam" );
        System.out.println( msg );
        resp.getWriter().println( msg );
    }
}
---------------------------------------------

Here is the stack trace:

When I check my code, the myService variable is always null, so the resource
is not being injected before I try to get the port. When I checked the
repository in geronimo, it looks like the generated web.xml does not include
the proper <service-ref> elements inside it but I can't figure out why they
aren't being generated. Thanks in advance for the help.
