How to start

[campioncino]

ok. I've created my own java project, and using Bearing i'm able to calculate geodedic distance between 2 point

Code:

double longitude1 = 13.00000,latitude1 =43.0000,longitude2 = 13.12320,latitude2 = 43.02310;
double dist=Bearing.calculateBearing(longitude1, latitude1, longitude2, latitude2).getDistance();

That's Fine...
More complex, i wanna create a startPoint "A", endPoint "B" and get the route between A-B, as a positions

Code:

GoogleMapsService service = new GoogleMapsService();
       double elevation1=service.getElevationFor(longitude1, latitude1);
       double elevation2=service.getElevationFor(longitude2, latitude2);
       GoogleMapsPosition p1= new GoogleMapsPosition(longitude1, latitude1, elevation1, "Start");
       GoogleMapsPosition p2= new GoogleMapsPosition(longitude2, latitude2, elevation2, "end");

Now i get the point on Google Maps ...
1)how can i calculate the route?
2)how can i convert the route in points?

That's all...

Thanks for helping me
