Build and run
Using Maven 2/3 :
mvn clean install tomcat7:run
This will start a Tomcat container at http://localhost:8080/routing with some test data.
The test data cover the Rhône-Alpes region in France. Test data are in geographic coordinates (WGS84, epsg:4326) with time(cost) = distance (meters).
