title: Send PUSH Notification to Android Client from java class on app-Engine
body: <p>I have the requirement to send a PUSH notification to an android client from my java class. The class has been written using the guidelines provided at the url : <a href="http://www.vogella.de/articles/AndroidCloudToDeviceMessaging/article.html" rel="nofollow">http://www.vogella.de/articles/AndroidCloudToDeviceMessaging/article.html</a> (Section 2.4 - Send Messages) This works fine on the standard application servers like JBOSS and Weblogic. </p>
  
  <p>But the application needs to be moved to google app-engine but the class throws a compilation error saying : 'The class javax.net.ssl.HostnameVerifier is not supported by GAE's Java runtime environment'. Similar error is thrown for 'SSLSession' class too.</p>
  
  <p>Is there a way this can be overcome ? Or is there is any other way to send PUSH notifications from Java classes running on the app-engine ?</p>
  
  <p>Thanks,
  Vinay</p>
