I've been beating my head against a wall on this issue for a a couple weeks, but I can't figure it out. I believe there must be a bug in MyEclipse's Web Service implementation, the JAX-WS Libraries, or in the Tomcat container.

If I create the extremely simple Web Service below with the @Resource annotation and then try to access the WebServiceContext, per lots of examples on the Web, I get a NullPointerException in the MyEclipse-generated client program.

The MyEclipse-generated code does not work.

Can you please take a look at this and see if you can reproduce this problem?

Thank you!!!

---------------------------


Very Simple Web Service:

1.
2. package servletws;
3.
4. import javax.annotation.Resource;
5. import javax.jws.WebService;
6. import javax.xml.ws.WebServiceContext;
7.
8. @WebService
9. public class HelloServlet {
10. @Resource WebServiceContext wsContext;
11.
12. public String hello(String msg) {
13. return "Servlet WS: " + wsContext.getUserPrincipal() // *** NullPointerException happens here! ***
14. + ": " + msg;
15. }
16. }


The web service deploys and I can get to its WSDL in the browser.

************
HOWEVER....
************

As with my production web service, as soon as the client web service hits the line above where the wsContext.get UserPrincial() is, I get a NullPointerException....as with my previous postings.

My really-simple Web Service Client is this:

1.
2.
3. package servletws;
4.
5. public class WebServiceClient
6. {
7.
8. /**
9. * @param args
10. */
11. public static void main(String[] args)
12. {
13. HelloServletService service = new HelloServletService();
14. HelloServletDelegate delegate = service.getHelloServletPort();
15.
16. delegate.hello("hello there Test!");
17.
18. }
19. }

package servletws; public class WebServiceClient { /** * @param args */ public static void main(String[] args) { HelloServletService service = new HelloServletService(); HelloServletDelegate delegate = service.getHelloServletPort(); delegate.hello("hello there Test!"); } }

=========

The WSDL is this:

I can send you the two MyEclipse projects if you would prefer.

I'm using MyEclipse 7.5.

Look forward to any possible reasons why I keep getting NullPointerExceptions.

Thanks
