RE: [eclipselink-users] no transaction for simple session bean - bug?

["Michael O'Brien" <MICHAEL.OBRIEN@xxxxxxxxxx>]

Yannick,
 Hi, are you running on Tomcat in GlassFish, JBoss or Jeronimo? 
 For reference, the following session bean similar to yours works fine with a default TRANSACTION persistence type.
 I am not using em.flush() - I rely on the non-extended persistence unit to commit to the database for me.

 Although it runs on WebLogic, behaviour should be similar - check your transaction-type in your persistenc.xml
 I am using JTA
  <persistence-unit name="example" transaction-type="JTA">

see:
http://fisheye2.atlassian.com/browse/eclipselink/trunk/examples/org.eclipse.persistence.example.jpa.server.weblogic.enterpriseEJB/ejbModule/org/eclipse/persistence/example/jpa/server/business/ApplicationService.java?r=2523
EJB.jar

@Local
@Stateless
public class ApplicationService implements ApplicationServiceLocal {

 @PersistenceContext(unitName="example", type=PersistenceContextType.TRANSACTION) 
 private EntityManager entityManager;

    public boolean insertObjects(List<Cell> classes) {
        boolean errors = false;
        try {
            for(int i=0; i< classes.size(); i++) {
                entityManager.persist(classes.get(i));
            }
           
        } catch (Exception e) {
            errors = true;
            e.printStackTrace();
        }
        return errors;
    }

WAR.jar: client
public class FrontController extends HttpServlet implements Servlet {
 @EJB(beanName="ApplicationService")
 public ApplicationServiceLocal applicationService;

        // Inserting multiple entities should be done in one transaction on the session bean
        getApplicationService().insertObjects(cells);       

Hope this helps
thank you

Subject: [eclipselink-users] no transaction for simple session bean - bug?

If I use the latest EclipseLink, calling following code doesn't write to the database:

@Stateless
public class TestServiceBean implements TestServiceLocal {

@PersistenceContext
private EntityManager entityManager;

public void createMachin(Machin machin) {
entityManager.persist(machin);
entityManager.flush();
}

}

Is this a bug? It works well when switching to Toplink Essentials.

If I use entityManager.flush, I get this (javax.persistence.TransactionRequiredException: Exception Description: No transaction is currently active):
