Here is the code :

{{{
#!java
for(int i=0; i < len; i++){
			hotel = hotelsList.getJSONObject(i);
			lat = hotel.getDouble(""lat"");
			lng = hotel.getDouble(""lng"");
			name = hotel.getString(""name"");
			JMAP.addHotel(lat, lng, name);
			}
}}}

and this is the addHotel method in JMAP class:

{{{
#!java
public static void addHotel(double lat, double lng, String name){
map.addMapMarker(
               new MapMarkerDot(name, new Coordinate(lat,lng)));
            }
}}}


JMAP is a class created from the DEMO class you offer."	defect	closed	normal		JMapViewer	latest	fixed	ConcurrentModificationException addMapMarker
