Appendix A. Notable GWT Projects
This appendix lists notable GWT resources, including add-on modules, applications, and tools. The projects listed here generally came to our attention through the GWT user group (http://groups.google.com/group/Google-Web-Toolkit) or the GWT contributor group (http://groups.google.com/group/Google-Web-Toolkit-Contributors). These groups are themselves an invaluable resource; they are where the creators and users of GWT share ideas, discuss problems, and in general learn about GWT happenings.
The GWT incubator (http://code.google.com/p/google-web-toolkit-incubator/) is a sibling to GWT that’s managed by the GWT team and is “used as a place to share, discuss, and vet speculative GWT features and documentation additions.” New features that future GWT releases may incorporate show up here first.
The GWT Google APIs package (http://code.google.com/p/gwt-google-apis/) is a collection of libraries for integrating GWT with other Google APIs, such as Google Gears. It was created by the GWT team and is maintained by a collection of contributors.
GWTx (http://code.google.com/p/gwtx/) is an extended set of the standard Java library classes on top of what’s provided by the GWT distribution. It currently includes PropertyChangeSupport, StringTokenizer, and more. It was created by Sandy McArthur.
