我在运行测试用例时遇到以下异常，对于我的服务类。

代码：

public class NativeServiceTest {

       static NativeService NativeService;
       private static Context  ctx;
       private static EJBContainer ejbContainer;

       @BeforeClass
       public static void setUpBeforeClass() throws Exception {

          ejbContainer = EJBContainer.createEJBContainer();      
          ctx = ejbContainer.getContext();
       }


       @AfterClass
       public static void tearDownAfterClass() throws Exception {
          ejbContainer.close();
        }


       @Test
       public void testGetCustomService() throws NamingException {
          Gson gson= new Gson();
          String id = "";
          NativeService converter = (NativeService) ctx.lookup("java:global/classes/NativeService");
          assertNotNull(converter);
          gson.fromJson(NativeService.getCustomService(id), Portlet.class);

       }
    }

NativeService.java

public class NativeService {

       @EJB
       DataService dataService;
       //
       //   
    }

我使用jta-data-source进行交易。

NativeService必须是EJBBean，例如@Stateless。还要确保测试与EJBBean在同一项目中。

没有提供EJBContainer提供程序：未找到提供程序名称
