Sadly, AppEngineJS is a ghost these days. It seems to have died around December and is a few releases back. It is also based on a no-longer-supported webapp framework that was part of RingoJS (the CommonJS framework that runs on Rhino).
That said, I'm still using Ringo/Rhino on GAE, and it's pretty solid. Interfacing with the Java runtime APIs is easy (actually, interfacing with anything Java is easy). Loading requests take about 5 seconds to return, and subsequent requests are very quick. The development pace on Rhino has actually picked up again in the last few months (they recently created a new Google Group <https://groups.google.com/forum/#!forum/mozilla-rhino> and migrated their code to GitHub <https://github.com/mozilla/rhino>), and as part of Google's Summer of Code, there is a project being mentored by the lead developer of Ringo going on to upgrade Rhino to use Java 7's invokeDynamic to boost performance even more. It seems like "V8 Envy" is lighting a fire under people these days. :) It would be really awesome, and probably much easier than creating a whole new runtime, if Google was truly interested in looking at new directions, to build a JS runtime on top of Ringo's CommonJS implementation (or even just Rhino). I think that'd be a great way to meet Javascript developers half way, if they could set up all the plumbing and provide a webapp-like framework so that everyone using Rhino didn't have to do it themselves. And if you really wanted to go the extra mile, get the Closure folks to tweak the library and compiler for server-side stuff. ;) -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
