GWT-OpenLayers 3+

Withgwt-olyou can write fast mapping applications for web and mobile in pure Java. Technically speaking, it is a GWT wrapper forOpenLayers 3+using theJSInterop-Features of theGWT-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.

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 SDKhere.
