For the past couple of weeks, I’ve been trying various web framework stacks to be used with Google App Engine. The ones that I gave a go, and gave a pass for various reasons, were Stapler (the enchilada that powers Hudson), Spring, and RestEasy + htmleasy.
The search continued and I came across Sitebricks, still in its alpha phase but it looks really promising. Simple and straightforward, nothing too magicky, and I got it working with GAE/J in no time.
