Subject Re: Can Cayenne run on google AppEngine/Java?

I haven't tried it, but it seems like it'd be easy enough set up.

Yes, reflection isn't supported.

Again, though, I think the real fitting point is not getting Cayenne
to run in entirety on the app engine as a java -> javascript
translated byte code, but to make sure that client-side ROP works on
the apps engine, with Cayenne running on the server-side.
