GWT (formerly the Google Web Toolkit) is a development toolkit for building and optimizing complex browser-based applications. Its goal is to enable productive development of high-performance web applications without requiring the developer to be an expert in browser quirks, XMLHttpRequest, and JavaScript. GWT is used by many products at Google, including the new versions of AdWords and Groups. It's open source and completely free (Apache 2.0 licensed).

GWT (formerly the Google Web Toolkit) is a development toolkit for building and optimizing complex browser-based applications. Its core feature is the Java to JavaScript compiler.

The official docs cover all the basics and advanced topics – it's a great place to start and you'll often come back to it when you want to expand your knowledge of the framework. The docs are sprinkled with example code, but if that's not enough for you, there are always the samples that come with the GWT bundle.

For more esoteric topics the GWT Google Group might be of help. Latest stable version of GWT is 2.8.2 (2017-10-19)

How does the live, real-time typing work in Google Wave?

I'm sure Wave doesn't poll the server every millisecond to find out if the other user has typed something... so how can I see what the other person is typing as they type? And without hogging the bandwidth.
