Push Notification is not sent to apple devices

Question

I'm using JavaPNS for sending push notification to apple devices. But it's not working. Code snippet from my app:

try {
    BasicConfigurator.configure();
    Push.alert("Hello World!", "D:\\myPushKeyStore.p12", "myPushKeyStorePass", false, "b3ead5d64ba0e08241e236f3ee041d8a9f036b39a0b0537e99a5f8b72ce40607");
}
catch (CommunicationException e) {
    e.printStackTrace();
}
catch (KeystoreException e) {
    e.printStackTrace();
}

Here is the error log:

Am I having any issue regarding keystore file?

Answer 1

Finally I found that the problem was due to the p12 certificate which was causing SSL Handshake Error.
I refer to Cannot send push notifications using Javapns/Javaapns SSL handshake failure solution in getting the correct p12 file. Thanks!
