Hello Chris. I'm also interested in building a scala app on the Google App Engine. I have a simple working (empty) lift/scala template here: http://dl.getdropbox.com/u/1127092/lift4gaeTEMPLATE.zip
But I haven't been able to cross the bridge from scala GAE app to wave robot. As I understand it there are examples of java wave robots floating around so I tried using their guidance Settings for bots: http://code.google.com/apis/wave/extensions/robots/ Java wave bot: http://www.vogella.de/articles/GoogleWave/article.html#robot Once I get this working I'll add it the code/how to information to this google wave: https://wave.google.com/wave/#restored:search:by%253Ame,restored:wave:googlewave.com!w%252BRz-PM7LmK On Oct 14, 1:02 am, chrislewis <burningodzi...@gmail.com> wrote: > Hi all, > > I've spent hours wrestling with getting some form of a working dev > environment for aScala(Lift) app on app engine.
