Miguel,
Hi! Why not just use the Wonder ERPrototype framework and some easy configuration using the Properties file? This way, it wouldn't be point and click, but it would be very easy to install the app on any DB you have around.
Hi!
Anyway, if you want to do point and click, 5.4 comes with Derby <http://db.apache.org/derby/> built-in, I think (not 100% sure, I'm still on 5.3). Derby would do the trick, I guess. Check out posts in this list about fixing some classpath issues in Apple examples that use Derby. I think Pascal did a Podcast about it.
