unit testing RequestDispatcherProvider with a JAXRSServerFactoryBean (Jetty getRequestDispatcher returns null)

[Paul Wilton <Pa...@bbc.com>]

Hi

Is there an easy way to test (inline) a JAX-RS service method that uses
RequestDispatcherProvider.

I have been using a JAXRSServerFactoryBean  for all my (integration)
unit tests for my typical JAX-RS methods.

 

However, when using a RequestDispatcherProvider, it calls
getRequestDispatcher on the context handler in order to delegate to the
resource (eg a JSP ), but the Jetty implementation of
ContextHandler.getRequestDispatcher  simply returns null - so the JSP
resource is never delegated to, and the service method returns a 500
status.

 

EG in the following  simple example,  when the RequestDispatcherProvider
is invoked, it calls the getRequestDispatcher("/test.jsp")  but the
Jetty implemtmnation of that method is hardcoded to return null

 

Any help appreciated:

Thanks

Paul

 

    @Before

    public void setup(){

        server = new MyRestServer();

        List<Object> providers = new ArrayList<Object>();

        RequestDispatcherProvider requestDispatcherProvider = new
RequestDispatcherProvider();

        requestDispatcherProvider.setResourcePath("/test.jsp");

        requestDispatcherProvider.setScope("request");

        providers.add(requestDispatcherProvider);

 

        JAXRSServerFactoryBean sf = new JAXRSServerFactoryBean();

        sf.setResourceClasses(MyRestServer.class);

        sf.setResourceProvider(MyRestServer.class, new
SingletonResourceProvider(server));

        sf.setBindingId(JAXRSBindingFactory.JAXRS_BINDING_ID);

        sf.setProviders(providers);

        sf.setAddress(REST_SERVER_URL);

        sf.create();

        sf.getDestinationFactory();

 

        httpClient = new HttpClient();

        getMethod = new GetMethod();

 

    }

 

 

    @Test

    public void getStatusMetadataServiceOk() throws Exception {

        String path = REST_SERVER_URL + "/servicestatus";

        URI uri = new URI(path, false);

        getMethod.setURI(uri);

 

        httpClient.executeMethod(getMethod);

 

        // verifiy the answer was actually hit..

        int status = getMethod.getStatusCode();

        String response = getMethod.getResponseBodyAsString();

        System.out.println(response);

        assertEquals(200, status);

    }
