My computer died and with it my mercurial repo, Trac and maven sites. So I figured I'll put my stuff "in the cloud". To try something new I decided not to use sourceforge or ops4j but look at google or Kenai. Since Kenai won't let you create a project without waiting for their approval I went with code.google.com
So far I've been pretty happy, the mercurial repo works ok, the issue tracker is fine for my humble needs (too bad there is no integration in NetBeans or Eclipse) and the Wiki is good enough.
Check it out at http://code.google.com/p/zoom-desktop/
To further the cloud experience I wanted to write some REST+JSON stuff and put it in google app engine, just for kicks. So I tried my hand at the google app engine plugin for eclipse and also the one for NetBeans. Both deliver what I expected and works quite nicely, thank you.
Since I haven't found my favourite framework for REST stuff in java I and a pal decided to start the Put JSON to REST project at http://code.google.com/p/pj2r/
It's chugging along, REST is fun and I'm learning that I didn't know half of what I thought I knew about HTTP.
The conclusion: google zooms. Jersey and JAX-RS zooms if you deal with XML but try to fine tune the JSON strings that JAXB spits out and you'll be pretty confused.
