[jboss-user] [EJB 3.0] - Re: Using EntityManager in a abstract super class

[skajotde]

My team problem like this resolve with inheritance.

public abstract class GeneralDataAccessManipulator implements DataAccessManipulator {
  | 
  |     protected abstract EntityManager getEntityManager();
  | 
  |     public void delete(Object entity) {
  |         if (!getEntityManager.contains(entity)) {
  |             entity = doMerge(entity);
  |         }
  |         try {
  | 			doDelete(entity);
  | 		} catch (Exception e) {
  | 			e.printStackTrace();
  | 		}
  | }
  | 
  | 
  | public class Specjalization extedns GeneralDataAccessManipulator {
  | 
  |       @PersistenceContext(name="puXXX")
  |       private EntityManager entityManager;
  | 
  |       protected EntityManager getEntityManager() {
  |            return entityManager;
  |       }
  | }
