Chris Lee has written a blog post which discusses his solution on integrating GWT RPC with Spring 2.x.

The differences from a conventional GWT-RPC service:

• No requirement to inherit from RemoteServiceServlet (or any other class for that matter)
• Addition of the annotation to indicate that this bean is an end point for GWT-RPC
  Automagic mapping of URLs (more on this below)
• Ability to use all of Spring’s DI, AOP and other services on the bean (its no different than any other bean)
• I’ve chosen to use so that Spring 2.5’s component scanning finds and registers this bean; alternately, could be omitted and the bean simply registered via XML.

IndicThreads has posted an interview with GWT Project Lead, Bruce Johnson. It’s an interesting read.

IndicThreads >> What’s the overall direction that GWT is taking?

Bruce Johnson>> We will continue to look for ways to make GWT easier to use and great for interoperating with other client-side technologies while continuing to produce better, faster output. The team is extremely passionate about this mission because we realize that by enabling developers, we are indirectly helping millions of end users, which is very gratifying.

Adam Houghton has created a CoverFlow implementation for GWT called GWTFlow.

GWTFlow uses standard GWT widgets for positioning the images and callouts to Script.aculo.us for the effects. All of the photos are just Image objects placed on an AbsolutePanel, with a little math behind the scenes to determine positioning & simulate perspective. Albums & images are retrieved via RPC calls to a Java service, which then calls out to Flickr’s public API using flickrj. GWT made development & debugging a breeze, with history & cross-browser support basically coming for free.

Thierry Ruiz is using GWT in his site called dotemplate which is a free, online web template generator. The stylish looking control panel used to customize the web templates was created using only basic GWT widgets.
