I have exception in my "delete" method but similar "add" method working correct.
Please help me with my problem))

Code:

26.03.2012 21:33:41 org.hibernate.event.internal.DefaultDeleteEventListener deleteTransientEntity
INFO: HHH000114: Handling transient entity in delete processing

Code:

   public void delBlockedProcess(String ip, String nameBlockProcess) throws SQLException{
      Session session = null;   
      
      try{
         BlockedProcess exemBlock = new BlockedProcess();
         exemBlock.setClientIP_id(ip);
         exemBlock.setBlockedName(nameBlockProcess);
         session = factory.openSession();
         session.beginTransaction();
         session.delete(exemBlock);
         session.getTransaction().commit();
      }catch(Exception ex){
         System.out.println("Error in delBlockedNameByIP  " + ex.getMessage());
      }finally{
         if(session != null && session.isOpen()){
            
            session.close();
         }
         
      }
      
   }

Hi,

When you do a new BlockedProcess() and an add(), it adds that new object into the database.
However, when you are doing a new() and then followed by a delete(), you are trying to delete an object that is not even present in the database. so, that should be why you are facing the issue.

what should you try is,
opensession()
beginTransaction()
find() the required entity from the database
delete() that entity fetched from database
commit.

This should work.
