 </div>

 <p>See the <a href="../../alternate-descriptors.html">Alternate Descriptors</a> page for the full details of how this feature works.</p>

 <p>For our example we'll use the standard "moviefun" code which contains a <code>Movie</code> entity and <code>Movies</code> 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.</p>

 <p>To add this to our application, we simply need a <code>test.ejb-jar.xml</code> in the same location that the regular <code>ejb-jar.xml</code> would be expected.</p>

 <p>That gives us the following files in our project:</p>

 <ul>
 <li>src/main/resources/META-INF/ejb-jar.xml</li>
 <li>src/main/resources/META-INF/persistence.xml</li>
 <li>src/main/resources/META-INF/test.ejb-jar.xml</li>
 </ul>

 <h2>The test.ejb-jar.xml</h2>

 <p>The normal <code>ejb-jar.xml</code> simply contains <code>&lt;ejb-jar/&gt;</code>, however the <code>test.ejb-jar.xml</code> we add an extra interceptor:</p>

 <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
 &lt;ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"&gt;
   &lt;assembly-descriptor&gt;
     &lt;interceptor-binding&gt;
       &lt;ejb-name&gt;Movies&lt;/ejb-name&gt;
       &lt;interceptor-class&gt;org.superbiz.altdd.MoviesTest$Interceptor&lt;/interceptor-class&gt;
     &lt;/interceptor-binding&gt;
   &lt;/assembly-descriptor&gt;
 &lt;/ejb-jar&gt;
 </code></pre>

 <h2>The TestCase</h2>

 <p>To enable our <code>test.ejb-jar.xml</code> in the test case, we simply set the <code>openejb.altdd.prefix</code> property when creating the embedded <code>EJBContainer</code></p>

 <pre><code> 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&lt;Movie&gt; 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();
          }
      }
  }
 </code></pre>

 <p>As noted in <a href="../../alternate-descriptors.html">the documentation</a>, several prefixes can be used at once.</p>

	</div>

	<p>See the <a href="../../alternate-descriptors.html">Alternate Descriptors</a> page for the full details of how this feature works.</p>

	<p>For our example we'll use the standard "moviefun" code which contains a <code>Movie</code> entity and <code>Movies</code> 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.</p>

	<p>To add this to our application, we simply need a <code>test.ejb-jar.xml</code> in the same location that the regular <code>ejb-jar.xml</code> would be expected.</p>

	<p>That gives us the following files in our project:</p>

	<ul>
	<li>src/main/resources/META-INF/ejb-jar.xml</li>
	<li>src/main/resources/META-INF/persistence.xml</li>
	<li>src/main/resources/META-INF/test.ejb-jar.xml</li>
	</ul>

	<h2>The test.ejb-jar.xml</h2>

	<p>The normal <code>ejb-jar.xml</code> simply contains <code><ejb-jar/></code>, however the <code>test.ejb-jar.xml</code> we add an extra interceptor:</p>

	<pre><code><?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>
	</code></pre>

	<h2>The TestCase</h2>

	<p>To enable our <code>test.ejb-jar.xml</code> in the test case, we simply set the <code>openejb.altdd.prefix</code> property when creating the embedded <code>EJBContainer</code></p>

	<pre><code> 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();
	}
	}
	}
	</code></pre>

	<p>As noted in <a href="../../alternate-descriptors.html">the documentation</a>, several prefixes can be used at once.</p>
