weird exception

[Edward Chen]

I have code like below, if update has a runtime exception, it will not go to Exception block and will continue the block left. Output will be

11
22
44

That is weird. What I expect is 11 33.

Please help. Thanks.

public Case updateCase(Case thisCase) throws Exception{			
		try {
			System.out.println("11");
			this.getHibernateTemplate().update(thisCase);	// throw RuntimeException: org.hibernate.StaleObjectStateException
			System.out.println("22");
		} catch (Exception e) {
			System.out.println("33");
		
			throw e;
		}
		
		System.out.println("44");
		
	
		return thisCase;		
	}

I don't see anywhere in your code where you are throwing an exception. Is line 4 supposed to throw an exception??
You also shouldn't being throwing exceptions inside your catch block.

Basic try/catch:

try
{
     //try to do something
     throw Exception
}
catch(Exception e)
{
      //print something
}

Edward: I understand what you're saying. You're correct that 11 22 44 is what you will see when there is no exception, and you'll see 11 33 when there's not. If you're seeing 11 22 44, then no exception is being thrown here. Perhaps StaleObjectStateException is being thrown internally, inside update(), which is printing a message and returning normally?

Sorry, give you confusion. when Line 4 throw a StaleObjectStateException， it will give me 11 22 44. It will be same as when there is NO exception. But what I want is when there is an exception, output will be 11 33.

What do you mean "thrown internally" ?

Spring framework provides a wrapper, org.springframework.orm.hibernate3.HibernateOptimisticLockingFailureException for this runtime exception. Is this wrapper class related to this weird thing ?

Thanks.
