    Newbie GenericGenerator from stored procedureProblem

    slavosk

      Hi,

      i have problems to get id from a stored procedure. I'm getting allways the "NOK" value from my Generator. (Problem with persistence context ?)

      Is it possible, or what am I doing wrong?

      
       @GenericGenerator(name="next_id", strategy="com.myapp.DBSequenceGenerator")
       @Id @GeneratedValue(generator="next_id")
       @Column(name = "product_id", unique = true, nullable = false, length = 20)
       @NotNull
       @Length(max = 20)
       public String getProductId() {
       return this.productId;
       }
      
      




      
      @Stateless
      public class DBSequenceGenerator implements IdentifierGenerator {
      
       @PersistenceContext
       EntityManager em;
      
       public DBSequenceGenerator() {
       // empty constructor
       }
      
       public Serializable generate(SessionImplementor arg0, Object arg1) throws HibernateException {
       try {
       Query q = em.createNativeQuery("select get_next_id from get_next_id('nativequery')");
       //........
       } catch (Exception e) {
       return "NOK";
       }
       return "OK";
       }
      }
      
      




      Thank you!
