Greetings, I am creating a Java based server to create push notifications for Apple’s

  • 0

Greetings,

I am creating a Java based server to create push notifications for Apple’s iOS APNs service. I have found Javapns on google code which seems to provide a simple basic framework to communicate with APNs, and which seems to be fairly wide used.

http://code.google.com/p/javapns/

However, reading Apple’s docs, there is an “enhanced format” for notifications which supports “expiry” i.e. setting a time (well, in seconds) for a notification to expire if it hasn’t yet been delivered. I do not see any way to set this using Javapns, and I am unsure how the APNs service handles expiry of notifications if you do not explicitly set it. So,

  1. Does anyone know how to support the enhanced notification format of APNs specifically how to set the expiry?
  2. Does anyone know how Apple handles notification expiry if it isn’t explicitly set?
  3. Does anyone have any suggestions that don’t require me to start from scratch, as the server is currently functional as is?

Thanks in advance.

Andrew

    I have recently made substantial contributions to the JavaPNS project, which lead to the release of JavaPNS 2.0 a few days ago. That version provides full support for the enhanced notification format, including the ability to set your own expiry.
