Google does not allow using Google Maps outside of the browser.” http://stackoverflow.com/questions/1303333/googleearth-inside-java-swing Das erkl¨art die Tatsache, das alle g¨angigen Versionen aus 3 Komponenten bestehen. 7 Es ist also illegal, rein Java zu verwenden. So dauert es ein paar Monate bis Jahre und lizenzrechtliche Probleme mit immensen Kosten treffen jeden beteiligten des Projektes.
