Play for Java shows you how to build Java-based web applications using the Play! 2 framework. This book starts by introducing Play! through a comprehensive overview example. Then, you'll look at each facet of a typical Play! application both by exploring simple code snippets and by adding to a larger running example. Along the way, you'll contrast Play! and JEE patterns and learn how a stateless web application can fit seamlessly in an enterprise environment. You'll also learn how a little Scala can go a long way in creating tight, efficient Java applications.
For this first episode of “Code-2020″, we have interviewed Guillaume Laforge, lead of the Groovy language and, for the Play framework, Guillaume Bort (CEO of Zenexity and founder of the... (RT @CODE_2020: Episode 1 is now live!

Why push the same information to all clients? Because this information may be costly to build or it is important every client gets the exact same, time dependent, information.
