title: Dynamically update google maps with received longitudes and latitudes
body: <p>I've written a java applet which sends longitudes and latitudes trough POST requests. I need to write a server page which will receive this data and dynamically shows a google map with the received points on it.  (php/etc...)</p>
  
  <p>I don't know how to start with this, because I really don't know what to do first.</p>
