NoInitialContextException in CXF Local Transport for testing the JAX-RS - jax-rs

Question

I am following this tutorial: https://cwiki.apache.org/confluence/display/CXF20DOC/JAXRS+Testing
But I get this error:
javax.naming.NoInitialContextException:Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
This is my local server class:
public class CXFLocalTransportTestSuite {
public static final Logger LOGGER = LogManager.getLogger();
public static final String ENDPOINT_ADDRESS = "local://service0";
private static Server server;
#BeforeClass
public static void initialize() throws Exception {
startServer();
}
private static void startServer() throws Exception {
JAXRSServerFactoryBean factory = new JAXRSServerFactoryBean();
factory.setAddress(ENDPOINT_ADDRESS);
List<Class<?>> resourceClasses = new ArrayList<Class<?>>();
resourceClasses.add(CommunicationWSRESTImpl.class);
factory.setResourceClasses(resourceClasses);
List<ResourceProvider> resourceProviders = new ArrayList<>();
resourceProviders.add(new SingletonResourceProvider(new CommunicationWSRESTImpl()));
factory.setResourceProviders(resourceProviders);
List<Object> providers = new ArrayList<Object>();
providers.add(new JacksonJaxbJsonProvider());
providers.add(new ApiOriginFilter());
providers.add(new AuthenticationFilter());
providers.add(new AuthorizationFilter());
factory.setProviders(providers);
server = factory.create();
server.start();
LOGGER.info("LOCAL TRANSPORT STARTED");
}
#AfterClass
public static void destroy() throws Exception {
server.stop();
server.destroy();
LOGGER.info("LOCAL TRANSPORT STOPPED");
}
}
And a client example:
public class CommunicationApiTest {
// [PUBLIC PROFILE]
// --------------------------------------------------------------------------------------------------------
#Test
public void getLinkedComponentsTest() {
// PATH. PARAM.
// ********************************************************************************************************
String userId = "1";
String componentInstance = "a3449197-cc72-49eb-bc14-5d43a80dfa80";
String portId = "00";
// ********************************************************************************************************
WebClient client = WebClient.create(CXFLocalTransportTestSuite.ENDPOINT_ADDRESS);
client.path("/communication/getLinkedComponents/{userId}-{componentInstance}-{portId}", userId, componentInstance, portId);
client.header("Authorization", "Bearer " + CXFLocalTransportTestSuite.authenticationTokenPublicProfile);
Response res = client.get();
if (null != res) {
assertEquals(StatusCode.SUCCESSFUL_OPERATION.getStatusCode(), res.getStatus());
assertNotNull(res.getEntity());
// VALID RESPONSE
// ********************************************************************************************************
assertEquals("> Modules has not been initialized for userID = 1", res.readEntity(GetLinksResult.class).getMessage());
// ********************************************************************************************************
}
}
}
Finally, this is the jax-rs implementation on the server side:
#Path("/communication")
public class CommunicationWSRESTImpl implements CommunicationWS {
#Path("/getLinkedComponents/{userId}-{componentInstance}-{portId}")
#GET
#Produces(MediaType.APPLICATION_JSON)
public Response getLinkedComponents(
#HeaderParam("Authorization") String accessToken,
#PathParam("userId") String userId,
#PathParam("componentInstance") String componentInstance,
#PathParam("portId") String portId) {
LOGGER.info("[CommunicationWSREST - getLinksComponents] userId: " + userId + " -- componentInstace: "
+ componentInstance + " -- portId: " + portId);
GetLinksResult result = new GetLinksResult();
result.setGotten(false);
result.setPortList(null);
if (userId != null && userId.compareTo("") != 0) {
if (componentInstance != null && componentInstance.compareTo("") != 0) {
if (portId != null && portId.compareTo("") != 0) {
TMM tmm = null;
javax.naming.Context initialContext;
try {
initialContext = new InitialContext();
tmm = (TMM) initialContext.lookup("java:app/cos/TMM");
result = tmm.calculateConnectedPorts(userId, componentInstance, portId);
} catch (Exception e) {
LOGGER.error(e);
result.setMessage("> Internal Server Error");
return Response.status(Status.INTERNAL_SERVER_ERROR).entity(result).build();
}
} else {
LOGGER.error("Not found or Empty Port Error");
result.setMessage("> Not found or Empty Port Error");
return Response.status(Status.NOT_FOUND).entity(result).build();
}
} else {
LOGGER.error("Not found or Empty Component Instance Error");
result.setMessage("> Not found or Empty Component Instance Error");
return Response.status(Status.NOT_FOUND).entity(result).build();
}
} else {
LOGGER.error("Not found or Empty userid Error");
result.setMessage("> Not found or Empty username Error");
return Response.status(Status.NOT_FOUND).entity(result).build();
}
return Response.ok(result).build();
}
}
Maybe the problem is the local transport is not correctly configured what launches the exception because of the lookup (see: server side):
TMM tmm = null;
javax.naming.Context initialContext;
try {
initialContext = new InitialContext();
tmm = (TMM) initialContext.lookup("java:app/cos/TMM");
result = tmm.calculateConnectedPorts(userId, componentInstance, portId);
} catch (Exception e) {
..

The problem is most likely because you are running your test in a Java SE environment that is not configured with a JNDI server. If you run your test as part of a WAR inside a Java EE app server, this would probably work just fine.
So you might need to either run your unit test inside an app server or you could try mocking a JNDI server like what is described here: http://en.newinstance.it/2009/03/27/mocking-jndi/#
Hope this helps,
