ObjectNotFoundException - But I know it might not be there

[mcaughey]

I've got a problem that I expect is not unusual. I may simply be approaching this the worng way. I'm doing a look up in a table where the primary key may not exists. I'm using session.load( class, Integer ) to find my object.

Person person = (Person)session.load( Person.class, new Integer(personId) );

person == null is always false.

So I do the following:

try{
 if(person.getPersonId() > 0);
}catch(ObjectNotFoundException e){
 // do nothing
}

// code continues

If the person object was not loaded the when I do the getPersonId() the ObjectNotFoundException is thrown. Well what I found out was there is a callback event listener handling the exceptions thrown in the concrete class of my Person Object. I cannot catch the exception it is being thrown to and handled by a class called DefaultLoadEventListener.

My code works fine, but my log files are filling up with stack traces everytime one of these are thrown, and I don't care that they are being thrown. They are logged as Errors in log4J so I cannot even adjust the log level with out potentianly missing other important logging info coming from that class.

Is there a better way?

Is there something I can do to turn off thoose nasty stacktraces for this senerio?

Thanks,
Michael

if you do not know about the primary key, the best practice is to use the methode Session.get(Class clazz, Serializable id), because when a persistent object with this id does not exit, then the method returns null
