Hy guys!
I would like to create an offline rooting application and want to use GH.
I walked through https://github.com/graphhopper/graphhopper/blob/master/docs/web/quickstart.md steps and I downloaded a certain map (used this one: http://download.geofabrik.de/europe/hungary.html). If I ran the application with java -jar *.jar jetty.resourcebase=webapp config=config-example.properties osmreader.osm=hungary-latest.osm.pbf then I could see the country, but I can not zoom in-out because the tiles turned to grey… Did I got the application what I needed? Or the database is too small to show detailed data? Or Am I miss something?
Thanx for your help! 
Best Regards:
VIktor
