 <p>The <code>org.apache.openejb.junit.ApplicationComposer</code> is JUnit test runner modeled after the way we've done testing internally in OpenEJB for years (since about 2006).
 It involves no classpath scanning at all.  If you want something to be in the app, you must build it directly in your testcase.</p>

 <p>With the <code>ApplicationComposer</code> you can do identical testing that OpenEJB uses internally, but with limited dependency on OpenEJB itself.  The main dependency is on the code
 that is used to build the actual applications:</p>

 <pre><code>&lt;dependency&gt;
   &lt;groupId&gt;org.apache.openejb&lt;/groupId&gt;
   &lt;artifactId&gt;openejb-jee&lt;/artifactId&gt;
   &lt;version&gt;4.0.0-beta-1&lt;/version&gt;
 &lt;/dependency&gt;
 </code></pre>

 <h1>Composing an Application</h1>

 <p>The main difference to the embedded <code>EJBContainer</code> API is building the application in the test code.  This is done with one or more methods in the test case annotated
 with <code>org.apache.openejb.junit.Module</code> using the following format:</p>

 <pre><code>@Module
 public &lt;return-value&gt; &lt;module-name&gt;() {
 </code></pre>

 <p>Where <strong>module-name</strong> is the name you wish to use for that module and <strong>return-value</strong> can be any one of the following:</p>

 <ul>
 <li>java.lang.Class</li>
 <li>java.lang.Class[]</li>
 <li>org.apache.openejb.jee.EjbJar</li>
 <li>org.apache.openejb.jee.EnterpriseBean</li>
 <li>org.apache.openejb.jee.Application</li>
 <li>org.apache.openejb.jee.Connector</li>
 <li>org.apache.openejb.jee.Beans</li>
 <li>org.apache.openejb.jee.jpa.unit.Persistence</li>
 <li>org.apache.openejb.jee.jpa.unit.PersistenceUnit</li>
 </ul>

	<p>The <code>org.apache.openejb.junit.ApplicationComposer</code> is JUnit test runner modeled after the way we've done testing internally in OpenEJB for years (since about 2006).
	It involves no classpath scanning at all. If you want something to be in the app, you must build it directly in your testcase.</p>

	<p>With the <code>ApplicationComposer</code> you can do identical testing that OpenEJB uses internally, but with limited dependency on OpenEJB itself. The main dependency is on the code
	that is used to build the actual applications:</p>

	<pre><code><dependency>
	<groupId>org.apache.openejb</groupId>
	<artifactId>openejb-jee</artifactId>
	<version>4.0.0-beta-1</version>
	</dependency>
	</code></pre>

	<h1>Composing an Application</h1>

	<p>The main difference to the embedded <code>EJBContainer</code> API is building the application in the test code. This is done with one or more methods in the test case annotated
	with <code>org.apache.openejb.junit.Module</code> using the following format:</p>

	<pre><code>@Module
	public <return-value> <module-name>() {
	</code></pre>

	<p>Where <strong>module-name</strong> is the name you wish to use for that module and <strong>return-value</strong> can be any one of the following:</p>

	<ul>
	<li>java.lang.Class</li>
	<li>java.lang.Class[]</li>
	<li>org.apache.openejb.jee.EjbJar</li>
	<li>org.apache.openejb.jee.EnterpriseBean</li>
	<li>org.apache.openejb.jee.Application</li>
	<li>org.apache.openejb.jee.Connector</li>
	<li>org.apache.openejb.jee.Beans</li>
	<li>org.apache.openejb.jee.jpa.unit.Persistence</li>
	<li>org.apache.openejb.jee.jpa.unit.PersistenceUnit</li>
	</ul>

	<h1>Example</h1>

	<p>Used in an actual testcase, that might look like so:</p>

	return unit;
	}

	@Module
	public EjbJar beans() {
	EjbJar ejbJar = new EjbJar("movie-beans");

	return p;
	}

	@Test
	public void test() throws Exception {

	try {

	} finally {
	userTransaction.commit();
