@John: Not sure if I'm parsing your comment correctly, but I'll give it a go: The benefit of adding state to a custom exception -- i.e., adding a custom field and allowing you to set it using setField() -- is that you can propagate out state/error information to outer scopes that catch the exception. This obviates the need to explicitly pass out error or status via other means. And yes, if you call setField(something) on your dbe instance, then the code which catches the exception would be able to see it -- you might want to add a DBGlobalsException.getField() method for that.
