Another J2ee Framework and Another AJAX Toolkit

I came across yet another J2EE framework this week. Open SubSystems and another AJAX toolkit. ThinWire they cleverly also put a page about the differences between Thin Wire and the Google Widget Toolkit. The interesting thing is that with ThinWire you have access to the Full Java API not just the ones available through the Google Widget Toolkit.

The only problem with all of these frameworks and toolkits is which one to choose.
