Push Notifications in iOS 7> on a private server
<p>I would like to implement a server-side push notification service for iOS. </p>

<p>When the application goes to the Background I need to send notifications to the client for different events and if it's necessary to wake app the application.</p>

<p>Currently in my system I have Apache tomcat Server and what I'm interested in to have a kind of tutorial of how that could be implemented. Is it possible to use for instance web-sockets, or what kind of alternatives such as TCP sockets from JAVA?</p>

<p>I have found some stand alone services such as <a href="http://airnotifier.github.io/" rel="nofollow">AirNotifier</a>, and <a href="http://www.easyapns.com/" rel="nofollow">EasyAPNs</a> but I would prefer not make complex my configuration by including more programming languages.</p>

<p>Thanks</p>
