7.15. WebServiceContext

The WebServiceContext is treated as an injectable resource that can be set at the time an endpoint is initialized. The WebServiceContext object will then use thread-local information to return the correct information regardless of how many threads are concurrently being used to serve requests addressed to the same endpoint object. 
@WebService
public class EndpointJSE
{
   @Resource
   WebServiceContext wsCtx;
 
   @WebMethod
   public String testGetMessageContext()
   {
      SOAPMessageContext jaxwsContext = (SOAPMessageContext)wsCtx.getMessageContext();
      return jaxwsContext != null ? "pass" : "fail";
   }
   ...
   @WebMethod
   public String testGetUserPrincipal()
   {
      Principal principal = wsCtx.getUserPrincipal();
      return principal.getName();
   }
  
   @WebMethod
   public boolean testIsUserInRole(String role)
   {
      return wsCtx.isUserInRole(role);
   }
}
