Google Web Toolkit (GWT) with Jdeveloper.

Google Web Toolkit (GWT) helps Java developers create Ajax applications more productively. GWT proposes a different way to create Ajax applications. It uses Java as a single programming language for both the client and server sides. GWT provides a compiler that translates the Java code on the client side into JavaScript and DTHML. This solution greatly simplifies the technology stack from the programmer’s point of view.

Jdeveloper has provided extension (gwtDeveloper) for Google Web Toolkit (GWT). You can get it using JDeveloper's Check for Updates mechanism.
