| = Alternate Descriptors |
| |
| See the link:../../alternate-descriptors.html[Alternate Descriptors] |
| page for the full details of how this feature works. |
| |
| For our example we’ll use the standard ``moviefun'' code which contains |
| a `Movie` entity and `Movies` session bean. To add a twist for testing |
| and demonstrate alternate descriptors, we will create an interceptor |
| that will be used only in our test cases. |
| |
| To add this to our application, we simply need a `test.ejb-jar.xml` in |
| the same location that the regular `ejb-jar.xml` would be expected. |
| |
| That gives us the following files in our project: |
| |
| * src/main/resources/META-INF/ejb-jar.xml |
| * src/main/resources/META-INF/persistence.xml |
| * src/main/resources/META-INF/test.ejb-jar.xml |
| |
| == The test.ejb-jar.xml |
| |
| The normal `ejb-jar.xml` simply contains `<ejb-jar/>`, however the |
| `test.ejb-jar.xml` we add an extra interceptor: |
| |
| .... |
| <?xml version="1.0" encoding="UTF-8" standalone="yes"?> |
| <ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"> |
| <assembly-descriptor> |
| <interceptor-binding> |
| <ejb-name>Movies</ejb-name> |
| <interceptor-class>org.superbiz.altdd.MoviesTest$Interceptor</interceptor-class> |
| </interceptor-binding> |
| </assembly-descriptor> |
| </ejb-jar> |
| .... |
| |
| == The TestCase |
| |
| To enable our `test.ejb-jar.xml` in the test case, we simply set the |
| `openejb.altdd.prefix` property when creating the embedded |
| `EJBContainer` |
| |
| .... |
| public class MoviesTest extends TestCase { |
| |
| @EJB |
| private Movies movies; |
| |
| @Resource |
| private UserTransaction userTransaction; |
| |
| @PersistenceContext |
| private EntityManager entityManager; |
| |
| public void setUp() throws Exception { |
| Properties p = new Properties(); |
| p.put("movieDatabase", "new://Resource?type=DataSource"); |
| p.put("movieDatabase.JdbcDriver", "org.hsqldb.jdbcDriver"); |
| p.put("movieDatabase.JdbcUrl", "jdbc:hsqldb:mem:moviedb"); |
| |
| p.put("openejb.altdd.prefix", "test"); |
| |
| EJBContainer.createEJBContainer(p).getContext().bind("inject", this); |
| } |
| |
| public void test() throws Exception { |
| |
| userTransaction.begin(); |
| |
| try { |
| entityManager.persist(new Movie("Quentin Tarantino", "Reservoir Dogs", 1992)); |
| entityManager.persist(new Movie("Joel Coen", "Fargo", 1996)); |
| entityManager.persist(new Movie("Joel Coen", "The Big Lebowski", 1998)); |
| |
| List<Movie> list = movies.getMovies(); |
| assertEquals("List.size()", 3, list.size()); |
| |
| for (Movie movie : list) { |
| movies.deleteMovie(movie); |
| } |
| |
| assertEquals("Movies.getMovies()", 0, movies.getMovies().size()); |
| |
| } finally { |
| try { |
| userTransaction.commit(); |
| fail("Transaction should have been rolled back"); |
| } catch (RollbackException e) { |
| // Good, we don't want to clean up the db |
| } |
| } |
| } |
| |
| public static class Interceptor { |
| |
| @Resource |
| private SessionContext sessionContext; |
| |
| @AroundInvoke |
| public Object invoke(InvocationContext context) throws Exception { |
| |
| sessionContext.setRollbackOnly(); |
| |
| return context.proceed(); |
| } |
| } |
| } |
| .... |
| |
| As noted in link:../../alternate-descriptors.html[the documentation], |
| several prefixes can be used at once. |

| == Warning on Tooling |
| |
| If you split your descriptors into separate directories, this support |
| will not work. Specifically, this will not work: |
| |
| * src/main/resources/META-INF/ejb-jar.xml |
| * src/main/resources/META-INF/persistence.xml |
| * src/*test*/resources/META-INF/test.ejb-jar.xml |
| |
| This support is *not* aware of any Maven, Gradle, Ant, IntelliJ, |
| NetBeans, Eclipse or other settings. |
