GWT & Errai

In modern web applications, the complexity of code deployed to the browser often exceeds the complexity of server-side code. Why write the simpler tier in toolable, typesafe languages but throw the constantly evolving user interface layer to the JavaScript wolves? Through compile-time source code translation using GWT, the Errai framework brings mature, proven, and toolable Java enterprise programming models to the browser. Errai lets your team share code between the client and the server and reuse functionality across application layers. In this session, you will learn how to build rich web applications the toolable, typesafe way, without boilerplate using Errai's concise programming model. Next-generation web applications can be built now by combining the best aspects of JavaScript and Java using Errai.

As a long-time Java EE developer and member of the GWT steering committee, Christian's focus is on developer productivity, in particular for web application development.

    I really enjoyed the presentation. It was good to see that GWT is being extended to build such a forward thinking web framework. Look forward to more of these.
