We had the honor to author a book for Packt Publishing about the amazing Play! Framework 2.
It was such a nice experience to write this book. It gave us yet another opportunity to share the knowledge we accumulated during our projects. And again in a technology that was, and that time, cutting edge and almost unknown (not even in 2.0 version). Today Play! Framework 2 is a top player in popular web frameworks in the Java or Scala world.
The book can be found on Amazon or directly at Packt Publishing.
