    Dependency Injection won't work

    suikast42

      Hi,

       

      I have an EAR-Archive with some modules ( JPA,EJB,WAR(JSF) and libs). So I want test my application with arquillian. But that seems not to be so easy.

       

      I think I don't understrand something.

       

      If I try to Inject a timerservice for example then my test fails.

       

       

      @RunWith(Arquillian.class)
      public class EditableServiceTest {
      
        @Deployment
        public static JavaArchive createTestArchive(){
          JavaArchive archive = ShrinkWrap.create(JavaArchive.class, "test.jar");
          return archive;
        }
      
       @Resource
       TimerService tm;
      
        @Test
        public void test(){
          Assert.assertNotNull(tm);
        }
      
      }
      

       

      So I have no depency to my modules. And I'm wondered what I'm doing wrong.

       

      My arqullian.xml

       

       

      <?xml version="1.0" encoding="UTF-8"?>
      <arquillian xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

          I forgot to say that I try the injection with @Resource and @EJB too.

          • 2. Re: Dependency Injection won't work
            suikast42

            I try the test with an EAR deployment. But still the same result.

             

             

            @RunWith(Arquillian.class)

            public class EditableServiceTest {

             

              @Deployment

              public static EnterpriseArchive createTestArchive(){

                return DependencyResolvers

                    .use(MavenDependencyResolver.class)

                    .artifact(

                        "groupID:artifactID:ear:3.0.0-SNAPSHOT")

                    .resolveAs(EnterpriseArchive.class).iterator().next()

                    .addAsLibrary(ShrinkWrap.create(JavaArchive.class).addClass(EditableServiceTest.class));

              }

             

              @EJB

              public DeviceOrderDAO edao;

             

              @Test

              public void test(){

                Assert.assertNotNull(edao);

              }

             

             

            }

             

            But still the same. My service is null. I'm so confused. What I'm doing wrong ??

              TimerService injection is only available to EJB's to my knowledge, your TestClass is not deployed as a EJB

               

              Try adding @EJB.mappedName="jndi-name-to-where-it-is-bound" to your EJB injection, and similar with the @Resource injections your trying to do

              • 4. Re: Dependency Injection won't work
                suikast42

                I tried the injection with mapped name as well. But the result is the same. I thought I can use my testcase like an EjB. Or must I do special think so that the DI works.

                 

                Thanks in advance

                  is it being deployed ok? Can you see the jndi names in the console log?

                  • 6. Re: Dependency Injection won't work
                    suikast42

                    Hi Aslak,

                    yes I can see the jndi names on the console. But what I don't understand is how the DI should work. I add my testcase in the EAR with    .addAsLibrary(ShrinkWrap.create(JavaArchive.class).addClass(EditableServiceTest.class).  For the DI my Testcase should be an EJB or not ?

                    Or mus I add my Testcase in an other way ??

                     

                    I have a further question. If I have more then one testcase ( I think that's the normal usecase )  would then arquillian restart the server in managed mode or redploy the ear in remote mode for every testcase ??

                      currently it will redeploy for every testclass, but keep the server instance running.

                       

                      The TestClass should only be a TestClass. Arquillain TestEnrichers should handle the DI part.

                       

                      Could you provide a complete example of what you don't get to work?

                        That's realy pity. Is that planed for the future ? For some cases I need this behavior. And a redeloyment needs a new initialisationphase for my application.

                        Then I don't know why the DI don't work .

                        That's a little bit difficult. I must send the complete code of the warehouse management system of my company. My chef won't be so happy about this situation. . I can try tomorrow wirte a little example.

                          Yes, this is definitly planned

                            Is there a timescheduöe for this feature ?

                              Hi Aslak,

                               

                              I do an upload o updloaded.to. Is a very simple project based on maven. I hope that helps. For me of course

                                Hi Aslak,

                                 

                                if I do the lookup with

                                 

                                  @EJB(mappedName="java:global/arq-test/arq-test-ejb/GreetingBean!com.siemag.arq.GreetingBeanLocal")

                                  public GreetingBeanLocal bean;

                                 

                                as you said then it will work. But the problem is my Appname varies in each project. But the common part for each project must be testable in everyy "special" project. I hope that was clear .

                                 

                                I see in the examples of arquillian this:

                                 

                                @RunWith(Arquillian.class)

                                public class GreetingManagerTest {

                                    @Deployment

                                    public static JavaArchive createDeployment() {

                                       return ShrinkWrap.create(JavaArchive.class, "test.jar")

                                          .addClasses(GreetingManager.class, GreetingManagerBean.class);

                                    }

                                 

                                    @EJB

                                    private GreetingManager greetingManager;

                                 

                                    @Test

                                    public void shouldGreetUser() throws Exception {

                                       String name = "Earthlings";

                                       assertEquals("Hello, " + name, greetingManager.greet(name));

                                    }

                                }

                                 

                                Why this DI not work with my code ?? I thought I can inject everything what I wan't with arquillian like I do in an EJB, isn't it so ??

                                    You could use the portable JNDI names of type "java:app/..." or "java:module/..." instead of "java:global/...". With the former two JNDI namespaces, you can perform lookups of resources that are local to the app, and thereby avoid the problem of adding the app-name to the JNDI name being looked up. You'll need to use java:app if you are performing a lookup of an EJB in a different module (the EJB is a different EJB module, compared to the Web module containing the Arquillian test). You can use java:module if the EJB and the Arquillian test are in the same module.
