jpa-2.0

I'm using Hibernate and JPA for a small project. Somehow when trying to obtain an typed Query, the java.lang.AbstractMethodError: org.hibernate.ejb.EntityManagerImpl.createQuery(Ljava/lang/String;Ljava/lang/Class;)Ljavax/persistence/TypedQuery is thrown; org.hibernate.ejb.EntityManagerImpl is from hibernate-entitymanager-3.3.2.GA.jar . This is not okay throwing the above exception: public Account read(Account entity) { EntityManager em = ManagedEntityManagerFactory.getEntityManager(); String jpql = JPQLGenerator.readAccount(); TypedQuery<Account> typedQuery = em.createQuery(jpql, Account.class

I am trying to create a new Java EE project using hibernate and JPA 2.0 on the glass fish server. Can you guys provide me some resources to configure the above so that they work seamlessly? I have tried using netbeans and generated the persistence unit by using the hibernate provider, but I end up getting this error: javax.persistence.PersistenceException: [PersistenceUnit: DBAppPU] Unable to build EntityManagerFactory Pascal Thivent First, install Hibernate support via the update tool (or follow the manual procedure ). Second, provide a JPA 2.0 persistence.xml to use Hibernate as JPA provider

This is my first post after many research on this problem. This example is running under Jboss 7.1 with seam 3.1 (solder + persistence + faces) with seam managed persistence context I'm facing a problem, the classical failed to lazily initialize a collection, no session or session was closed: org.hibernate.LazyInitializationException: failed to lazily initialize a collection, no session or session was closed when using a converter on Entity beans. The aim is to stay 100% Object oriented, by reusing the JPA model. in beans.xml, org.jboss.seam.transaction.TransactionInterceptor is activated

I have been at this for weeks. I have tried eclipselink and now just plain JPA. I keep getting the same issue. Everytime I try to flush my entity manager I get 'javax.persistence.TransactionRequiredException: no transaction is in progress' exception. I know its something to do with how I have everything wired but I can't figure it out. I have tried writing JUnit tests to test, but since I am new to spring that has a entirely different set of issue. Some things to note: I am not using a persistence.xml since I am using spring 3.1 * App Server: WebSphere 8.5 (Liberty Profile) * exception [ERROR

I'm thinking if i use maps like Map<String,List<Entity>> or Map<Long,List<Entity>> it will help me with a few things, but I couldn't find any example to map that kind of map. My question is, is it possible to do that kind of mapping in JPA standards, and what kind of annotation I should use? Yes, it's possible to create either of those Maps. Why not try it and answer your own question? It would be faster than passively asking here. As for JPA, I would suggest a better abstraction than a Map for holding onto that data. This feels too generic for me. That might be what you're going for, but JPA
