    Handling exception

    Ales Dostal Newbie

      Hi,
      I use Glassfish v2, Seam 1.2.1, JTA, TopLink, JPA.

      When I try execute any methods which not commit, thow any exception, for example:
      Local Exception Stack:
      Exception [TOPLINK-4002] (Oracle TopLink Essentials - 2.0 (Build b58g-fcs (09/07/2007))): oracle.toplink.essentials.exceptions.DatabaseException
      Internal Exception: com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Cannot delete or update a parent row: a foreign key constraint fails (`dostal/uzivatele_role`, CONSTRAINT `fk_role_name_uzivatele_role` FOREIGN KEY (`role_name`) REFERENCES `roles` (`role_name`) ON UPDATE CASCADE)
      Error Code: 1451

      How I can handle this transaction exception?
      I want in view show that action isn't access. Now exception throw only in server console.

      I want use some localization. For example: Error Code is 1451 = Cannot insert because....

      Thanks all!
