I am using Hibernate 4, Spring 3 and JSF 2.0 and Weblogic 10.3.6 I have the following in DAO class
CriteriaBuilder cb = entityManager.getCriteriaBuilder(); CriteriaQuery<Request> c = cb.createQuery(Request.class); When I run my application I am getting the following exception.
javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria /CriteriaBuilder; java.lang.NoSuchMethodError: javax.persistence.EntityManager.getCriteriaBuilder()Ljavax/persistence/criteria /CriteriaBuilder; at net.test.request.dao.RequestDAOImpl.getRequest(RequestDAOImpl.java:51) I did not use JPA1 jars, however I am still getting this exception. Not able to figure how to get rid of this exception. Any help is highly appreciable.
Thanks

The method EntityManager.getCriteriaBuilder is a part of JPA 2 (which is part of Java EE 6), which is not provided and/or turned on by default in WebLogic 10.
Here is a link which provides instructions that may fix your problem. If not, you'll need to start googling "weblogic 10 jpa 2" and see if you can find a solution that works for you.
If none of these solutions work, your last resort will be to redesign your application to only use JPA 1 methods. To use JPA 1 you must limit yourself to the classes and interfaces defined here:
[update]
Or - since you are using Hibernate anyways, don't rely so much on JPA classes. Use hibernate specific classes instead. Hibernate has had criteria since 3.x. Instead of an EntityManager you create a Hibernate session factory. Then you can do:
import org.hibernate.Criteria; import org.hibernate.Session; import org.hibernate.SessionFactory; ... Session session = sessionFactory.openSession(); Criteria crit = session.createCriteria(Person.class); Your code is now locked into using Hibernate as your persistence provider. In my case we always use Hibernate so it's not a real problem. This is a question you have to decide for yourself. If your application can tolerate being locked into Hibernate, this should give you the functionality you need while still running on WebLogic.
