JBoss 4.2.1 doen´t seem to support JPA Injection in servlets either.
Trying the same WAR i have tryed with 5 beta2, I´m facing the following
problems:
The Persistence Unit is not considered automatically.
I had to manually start the EMFactory up from a Filter.init or some
ServletContextListener, loading persistence.xml from WEB-INF/classes/META-INF.
The manual startutp complains some a lack of access to Transaction Managers, so
I had to add the following properties in persistece.xml:
| <property name="hibernate.transaction.factory_class"
value="org.hibernate.transaction.JTATransactionFactory"/>
| <property name="hibernate.transaction.manager_lookup_class"
value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
| <property name="jboss.entity.manager.jndi.name" value="java:jpa/TesteJPA"/>
| <property name="jboss.entity.manager.factory.jndi.name"
value="java:jpa/TesteJPAFactory"/>
|
Anyway the JNDI Tree doens´t show any new entries for my JPA Componentes
The Servlet (see code below) is neither receiveing JPA Injection nor
UserTransaction Injection.
| public class ServletJPA extends HttpServlet {
|
| @PersistenceUnit(unitName="java:jpa/TesteJPAFactory")
EntityManagerFactory emf;
| @Resource(name="java:UserTransaction") UserTransaction ut;
|
| ... doGet (...) {
| doJPA();
| }
|
| private String doJPA() throws NotSupportedException, SystemException,
RollbackException, HeuristicMixedException, HeuristicRollbackException {
|
| EntityManager em = null;
| try {
| getServletContext().log("emf == null ? " + (emf == null)); //
true !
| getServletContext().log("ut == null ? " + (emf == null)); //
true !
| ut.begin();
| em = emf.createEntityManager();
| MyEntity x = new MyEntity(...);
| em.persist(x);
| ut.commit();
| return "new ID :" + x.getId();
| } finally {
| if (em != null) em.close();
| }
|
| }
|

I see comments in this thread saying that only @EJB infection is missing...
Is there something I´m missing ?
