How to handle transaction exception

Question

Hi,
I am using jdev 11g.
I need to catch the exception in my transaction like (table not found, column must not be null, column not found, ...)
hereunder is my code.
  public void saveOsaUser(OsaUser osaUser) throws Exception {
    EntityManager em = getEntityManager();
    try {
      utx.begin();
      em.joinTransaction();
      em.persist(osaUser);
      utx.commit();
    } catch (Exception ex) {
      try {
        utx.rollback();
        throw new Exception(ex.getLocalizedMessage());
      } catch (SQLException sqle) {
        throw new Exception(sqle.getLocalizedMessage());
      } catch (IllegalArgumentException iae) {
        throw new Exception(iae.getLocalizedMessage());
      } catch (EJBException ejbe) {
        throw new Exception(ejbe.getLocalizedMessage());
      } catch (RuntimeException re) {
        throw new Exception(re.getLocalizedMessage());
      } catch (Exception e) {
        throw new Exception(e.getLocalizedMessage());
    } finally {
      em.close();
  }Whatever the error type, i always get the message : Transaction does not exist.
Kindly advice how can handle these SQL error (table not found, column must not be null, column not found, ...)
