GWT on Python App Engine

Question

I have a python app engine code (matured backend) - and we are now planning to have a front end for that code.

I was wondering whether it is possible to implement G

Answer 1

I use GWT with Python quite a bit - the JSON interface works perfectly well. Your GWT front-end is still written in a java-like syntax, and you still need the Java toolchain to actually compile it down to HTML/Javascript, but it doesn't care what language the backend is written in.

As for how this is accomplished - the GWT toolchain is completely independent of GAE, there's no executable Java on the AppEngine side. You design and write your frontend in GWT on your own system, and then compile it to HTML/JS, which is what you upload to GAE.
