Google Maps JavaScript API Example: Simple PushPins

import java.io.BufferedWriter; import java.io.FileWriter; import java.io.IOException; /** *

* This class demonstrates how to use the Goolgle Maps API with java. Google * Maps is based on Javascript which is similar to, but not the same as, Java. * This class writes an html file to disk and then launches an external web * browser to view the map. *

* This code is based on an example from the Google Maps website:
* http://code.google.com/apis/maps/documentation/examples/marker-simple.html * * The documentation for all things related to Google Maps is in the Google * Maps API: http://code.google.com/apis/maps/documentation/ *
