The Play 2.0 framework is looking better and better everyday:

I had blogged a while ago about “Does Java Have an answer to Node.js”. It looks like the best answer is Play 2.0. Play 2.0 uses all the technologies I mentioned in the previous post (netty, akka, scala). 

It also looks like Play 2.0 will be THE web framework for Scala. Yeah you could use:

• Scalatra - Which just gives you routing
• Lift - IMHO this framework is kind of dorky and reminds of Tapestry

But then again Play is using a more modern network libraries (Scalatra and Lift still rely mainly on 1 thread per request via servlet container) and is going to be supported by the people who came up with the language.

I wonder if Spring Source will come out with a Scala Spring Web Framework. They already have Groovy (Grails) and Java (Roo) .
