Oracle LONG datatype fetching fails on superclass Criteria query ---------------------------------------------------------------- Key: HHH-3395 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3395 Project: Hibernate3 Issue Type: Bug Environment: Oracle 10 Windows XP Hibernate 3 Weblogic 9.2 Reporter: Ville Anttonen I have dao-layer method like this. public PersistentQuery getPersistentQuery(String userId, long queryId){ .... Criteria criteria = m_session.createCriteria(PersistentQuery.class); criteria.add(Expression.eq("userId",userId)); criteria.add(Expression.eq("id",new Long(queryId))); return (PersistentQuery) criteria.uniqueResult(); ..... } Previous code throws "Stream already closed" exception. PersistentQuery is abstract class and it's subclasses contains UserType - field that wraps Oracle's long varchar field. I can fix this by creating criteria by subclass like " Criteria criteria = m_session.createCriteria(PersistentOrganizationQuery.class); ". We're migrating from ingres -> oracle and in ingres previous implementation worked fine. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
