Effectively, I access the map pane via a JMapFrame :
--------Code-----
JMapFrame map= new JMapFrame();
map.showMap(mapcontext);
map.addMouseListener(new MapMouseAdapter() {
public void onMouseClicked(MapMouseEvent ev) {
// Get the world position of the mouse
DirectPosition2D pos = ev.getMapPosition();
System.out.println(pos.x +pos.y);
}
});
---------------------------------------------------------------
Thank you a lot.
