This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
I have an object called SearchCriteria with about 20 attributes, each one being a criteria via which one could search.
I need to build a db query based on any of these criteria. I'd like to programmatically loop through the object's attributes testing each one for null and then taking action on the ones that are not null. How do you programmatically loop through an object's attributes?
You could do this with reflection. But I think you could come up with a better solution. Hibernate has a criteria class. You could look at that.

I can definitely do this using hibernate restrictions, but the difficulty is that these criteria come from up to 7 tables and in order to be able to use the restrictions I need to fetch join all 7 tables. I'm only displaying data from 2 of these tables so why do the huge fetch? Big waste of resources.
So I'm trying to come up with a different way of finding the objects.
