So, http://www.sun.com/glassfishv3 suddenly stopped 404ing.

I’ve been trying out various Prelude/Previews for a loooong time, so it’s really nice to see it finally ship.

From a (J)Ruby viewpoint,  this is the appserver that was wrapped up in the glassfish gem, only this time it’s a full-featured (and supported) product. I’ve run Sinatra / Rack apps on it with no problem at all.

Other bits that I’m looking forward to playing with are:

  • monitoring
  • the REST API (which looks pretty comprehensive : asadmin is now a http client)
  • custom profiles, like the Web Profile (if you don’t need the kitchen sink)

As ever, the docs are top notch. If you want to get the most out of JRuby on Glassfish, here’s a good tuning post.

You can even run Java apps on it if you want to.

Anyway, congratulations are in order to the GF team – there are far more knowledgeable posts than this linked from The Aquarium.
