GWT-OpenLayers 3+
With gwt-ol you can write fast mapping applications for web and mobile in pure Java. Technically speaking, it is a GWT wrapper for OpenLayers 3+ using the JSInterop features of the GWT SDK. The project consists of two parts:
- a GWT wrapper for OpenLayers 3+ (gwt-ol3-client)
- a demo module for showing wrapper functionality (gwt-ol3-demo)
You can build (mvn package) and run (mvn gwt:devmode) the application using Maven.
The dev mode server hosts the demo under the /demo path. Once the
server starts, open the printed URL (for example
http://localhost:9876/demo) in your browser to explore the examples.
If you want to build the application without Maven please consider the following hints:
- Building the application with older GWT-SDK than 2.8.0-beta1 will not work. You can download the latest SDK here.

gwt-ol is actively tested with OpenLayers 10.8.0 and generally works with other 10.x releases. If you require support for earlier versions of OpenLayers, use a matching gwt-ol release.
