JAX-RS cannot inject @Resource WebServiceContext

[Himai Minh]

I have a servlet-based JAX-RS example:

//Only relevant part shown.
@Path("/students")
@DeclareRoles({"teacher", "student"})
public class StudentServiceImpl implements StudentService {
	
	private StudentManager manager = new StudentManagerImpl();

         private Course course = new Course();
         @Context
         SecurityContext securityContext;
         
         @Resource
         WebServiceContext webServiceContext;

             ....

         @GET
	@Produces(MediaType.TEXT_XML)
        @RolesAllowed("teacher")
        @Path("/{studentId}")	
	public String getStudent(@PathParam("studentId") String strStudentId) throws Exception {		
		Util.log("GET students/{studentId} [studentId=" + strStudentId + "]");
                Util.log("User principal name injected from @Context security context :"+ securityContext.getUserPrincipal().getName());
               if (webServiceContext == null ){
                  Util.log("Web service context is null.");
               } 
               else{
               Util.log("Web service context "+ webServiceContext.getUserPrincipal().getName());
               }
              ......

When the client connect to this get method using user name as john, the output on the server is:
INFO: GET students/{studentId} [studentId=13005529]
INFO: User principal name injected from @Context security context :john
INFO: Web service context is null.

Obviously, @Context can inject the security context which contains john as the user principal.
But, I think @Resource WebServiceContext only works for JAX-WS service , not JAX-RS service. The WebServiceContext injected is null.

Correct: the WebServiceContext is only for JAX-WS.
