We've been using the same Object Relational Mapping tool for years now (TopLink) but because lack of support by Oracle we're considering looking at some other tools. I'm looking for some opinion/feedback on what some of the best FREE technologies there are out there?
You did not say whether you just wished to find something for future projects or if you also need to retrofit the solution back into existing applications. That could have a big impact on your technology choice.
Also, you did not say if you have used DAOs in your existing architecture, which will make changing your persistence technology choice much easier.
