[Building Sakai] Sakai GWT

[Thomas Amsler]

If you are not proficient in JavaScript but know Java, I would
recommend GWT as well. It takes care of generating consistent and
efficient JavaScript that works well across all modern browser.

We use GWT quite heavily in gradebook2:

I have also written a simple tool, SGS, that uses GWT:

Also, GWT has dramatically improved since v 2.x, using MVP, UI-Binder, etc.

Best,
-- Thomas
