POeclipselink: Missing Transaction with different jar's
text
Body
copied!<p>I have a JEE application. The classes of these JEE application are packaged in two different jar's which are both member of the EAR file.</p> <p>Let's say I have a JPA Entity "DataEntity" (packaged in the jar "a.jar"). </p> <p>In the first JAR file "a.jar" is also stored following class:</p> <pre><code>@Stateless @LocalBean public class A_Bean { @PersistenceContext(unitName = "testApp") private EntityManager em; public void testMethod(DataEntity obj) { if (em.contains(obj) log.info("CONTAINED a 1"); else { obj = em.merge(obj); em.refresh(obj); } if (em.contains(obj) log.info("CONTAINED a 2"); } } </code></pre> <p>In the second JAR file "b.jar" I have following class:</p> <pre><code>@Stateless @LocalBean public class B_Bean { @PersistenceContext(unitName = "testApp") private EntityManager em; public void testMethod(DataEntity obj) { if (em.contains(obj) log.info("CONTAINED b 1"); else { obj = em.merge(obj); em.refresh(obj); } if (em.contains(obj) log.info("CONTAINED b 2"); } } </code></pre> <p>Now I assume the following calls will be called from outside of the EJB container (means the specified DataEntity "dataObj" is currently not managed by the EntityManager):</p> <pre><code>a.testMethod(dataObj); </code></pre> <p>shows the expected output:</p> <pre><code>CONTAINED a 2 </code></pre> <p>But if I call </p> <pre><code>b.testMethod(dataObj); </code></pre> <p>I get a </p> <pre><code>Exception: javax.persistence.TransactionRequiredException at org.jboss.as.jpa.container.AbstractEntityManager.transactionIsRequired(AbstractEntityManager.java:692) at org.jboss.as.jpa.container.AbstractEntityManager.merge(AbstractEntityManager.java:547) at B_Bean.testMethod(B_Bean.java:xxx) ... </code></pre> <p>Also adding </p> <pre><code>@TransactionAttribute(TransactionAttributeType.REQUIRED) </code></pre> <p>not helps.</p> <p>And now after I moving the class B_Bean into the a.jar file also the B_Bean class works as expected.</p> <p>Must be packaged all EntityBeans in the same jar file? Is there is a trick how to package Entity classes in different jar files?</p> <p>My Environment:</p> <ul> <li>JBoss 7.1.1</li> <li>eclipselink 2.5.1</li> </ul> <p>Thanks, Steffen</p>
