Use Rhizosphere with Google Web Toolkit

posted 22 Feb 2011, 15:45 by Riccardo Govoni
After more than a month of sustained work, and over 3 months since the last update, we are finally releasing a new version of the Rhizosphere library (v 0.5) which includes full support for Google Web Toolkit applications.

You can now use Rhizosphere in any GWT application, simply by including the brand new Rhizosphere GWT module in your project. Rhizosphere support for GWT works by providing a Java facade to the underlying javascript library that will be embedded in your application, but it's not limited to just that.

It includes a whole set of features dedicated to GWT developers:
  • asynchronous inclusion of Rhizosphere libraries, so you can have them injected in your application only when the user needs it, minimizing performance impact,
  • use your own POJOs to define the datapoints to visualize,
  • coupled with a powerful annotation-based visualization configuration mechanism,
  • full support for GWT widgets and UiBinder templates to define the visualization UI elements,
  • full support for Google Visualization APIs for GWT to let you use Rhizosphere as a standard Google Visualization even within GWT.
To help you get started with Rhizosphere GWT, we have prepared a lot of material:
  • Comprehensive documentation on how to install, setup and use Rhizosphere within your GWT app,
  • Javadocs for the entire Rhizosphere module,
  • a working demo application at rhizospheregwt.appspot.com that includes annotated examples of all the features supported by the module.
Have a look at it. Once you are ready, you can download the module jar file from the Rhizosphere downloads area and follow the instructions to start using it in your GWT app.

For this release, we'd like to thank Dino Derek Hughes of Google UK that kickstarted the whole GWT branch developing the first proof of concept integration of the Rhizosphere library.
