title: Edit the host link for a web service in tomcat
body: <p>I am quite new to programming with JSPs, servlets and also android programming.
  I am getting <code>unknownhostexception</code> when i post from my jsp file. I came to know that the host I am using is not correct. My specific error is <code>java.net.UnknownHostException:android.googleapis.com</code> whereas it should be <code>android.googleapis.com/gcm/send</code>
  Please help me change the host name!!!</p>
