Paul has announced the availability of Jersey 1.1.1 EA, based on the draft for JAX-RS 1.1 (see JAX-RS 1.0 spec and Changelog). To learn more about Jersey you can see the Getting Started Document and the Jersey User's Guide, check out Paul and Marc's Webinar, or browse through previous entries. Jersey is also collaborating with JFA's Atmosphere framework, and, since Paul is a fan of Scala, also supports Lift. Overall, very good movement towards GFv3. More details at Paul's announcement.

The late sixties and seventies saw an explosion of programming languages but then we went through a consolidation. I am still grateful that Java saved me from C++, but I like the renewed interest in other languages. Languages with following include Ruby('95), Python('91) and Erlang('87) as well as newer additions like Groovy('03) and Scala('03). Paul certainly likes Scala, here is his JavaOne Jersey Demo in Scala.

Many of these languages are using our trusty JVM, now under Open Source. That can simplify development and adoption, so maybe we will have another golden age of Programming Languages!

I'm beginning to think we "undersold" GFv3 TP2 when we called it a Technology Preview as pretty much anything we are throwing at it works! Check out Vivek's latest note on Scala Lift Framework. Starting with a Maven Archetype, it creates a Scala Lift project using a Derby database that can deploy on GFv3 and, with a small change it can use v3 tp2 embedded for ease of development through mvn glassfish:run. Neat!

A tip from Paul Sandoz: Deploying Scala resource classes; this includes deploying onto GlassFish.

Paul shows how to use Scala and the latest Jersey to implement a simple REST request. The Scala code looks very readable and Paul includes commentary on the code. Check it out!

I am looking forward to an explosion of experimentation in Language Design, all of them running on the JVM and on GlassFish (specially v3) on the server-side.
