Re: [SPAM] Re: iBATIS for swing application
Jeff,
It helps a lot, I didn't knew abator also can generate a generic DAO.
Is it recommended to use the svn version?
Thx!

I'm tempted to say "trust me, it's better". But I think it would be
interesting for you to do some reading about it. This is the classic
question regarding the Singleton design pattern.
Do a google query for "singleton vs static" and you'll get a lot of hits.
Here's a good starting point:
http://www.kamalmeet.com/wordpress/2006/06/22/singleton-vs-static-classes/
The main issues are:
1. Better control of creation
2. Easier to subclass
These may, or may not, matter to you.

What's the benefit of using this factory as a Singleton?
One of my co-students suggested making all methods static,
so you can use Factory.getXxxDAO() instead off
Factory.getInstance.getXxxDAO();
but I'm not sure about that....

The SVN version is very stable and has a few extra features (it now
generates countByExample and updateByExample methods) , but the 1.0 version
should be fine too. I think you could use either.
