I am using spring + hibernate,
i am getting following error after saveOrUpdate into a table fails and i am trying to execute SQL query after failure

The code in Controller as is below

Code:

@Controller
@Transactional
public class AirportController {

 @RequestMapping(value = "/displayAddAirport")
    public String displayAddAirport(@ModelAttribute("newairport") Airport newairport,Model model)throws Exception{
     
     try{
     airportDao.saveAirport(newairport);
  
     }
   catch(Exception exc){
// trying to read some other table data fails
   airtportDao.getData();
  }
}
}

The error is

Code:

org.hibernate.AssertionFailure: null id in XXXXXXX entry (don't flush the Session after an exception occurs)
   org.hibernate.event.def.DefaultFlushEntityEventListener.checkId(DefaultFlushEntityEventListener.java:82)

You are not supposed to use the session after an exception occurs. Quote from the Hibernate documentation at http://docs.jboss.org/hibernate/core/3. ... exceptions:

Quote:

If the Session throws an exception, including any SQLException, immediately rollback the database transaction, call Session.close() and discard the Session instance. Certain methods of Session will not leave the session in a consistent state. No exception thrown by Hibernate can be treated as recoverable. Ensure that the Session will be closed by calling close() in a finally block.
