The ebook version has already been available for a couple of weeks, but the print version of GWT in Practice is now available for order on the Manning website. You will also get the ebook free, when you order the print version. GWT In Practice is written by Robert Cooper and Charlie Collins who are the creators of the and are active members of the GWT community. The book is aimed at more advanced users of GWT and covers practical topics such as:

• Communicating with servers using GWT RPC, XML, JSON, SOAP, streaming, and Comet.
• Integrating with Legacy and Third-Party Javascript libraries.
• Packaging, deployment, and distribution.
• Integration with J2EE technologies such as JPA, Spring and Hibernate.

I have the ebook version and so far I’ve read up to Chapter 8. I will post a review once I finish. If you are looking for the book on Amazon, it is supposed to be in-stock on May 15th.
