GIN (GWT INjection) brings automatic dependency injection to Google Web Toolkit client-side code. GIN is built on top of Guice and uses (a subset of) Guice's binding language. (See GuiceCompatibility for details.) By using GWT's compile-time Generator support, GIN has little-to-no runtime overhead compared to manual DI.

GIN 1.0 requires GWT 1.5 or higher and Guice 2.0, for Gin 1.5 you'll need to use the Guice snapshot distributed with Gin or the soon-to-be-released Guice 3.0.

Status

GIN is substantially feature-complete, well-tested, and in production use by many teams at Google. GIN 1.5 was released in February 2011. You can download the release, check out the source and build (ant dist) or add a dependency if you use maven.
