[FIXED] Hibernate - on the stack or on the heap?

Issue

As a Java programmer, you usually keep two truths in your pocket:

• Instance variables and Objects lie on Heap.
• Local variables and methods lie on the Stack.

Now that I use Hibernate in just about everything, I realize I'm not as sure of myself.

Are there some good rules of thumb for using hibernate and knowing where your memory lives?

Solution

I'm not really sure what you mean. I do know that all objects (Hibernate or other), even if you only have a local reference to them, go on the heap.

I'd worry more about the correctness of your code than this sort of thing, I doubt it'll noticeably affect performance. One database query would dwarf the possible speed difference.
