Error when using / initializing APNS

[Jakob Jenkov]

I am trying to use Java APNS - an open source project - to send push
notifications to iPhones. I am getting an error, though.

I have used a .pem file as certificate. Should this have been a .p12
file? I am not sure what the difference is, but I read somewhere
online that there is a difference between these file formats.

Here is the code:

ApnsService service =
APNS.newService()
.withCert("gpk.pem", "XXXX")
.withSandboxDestination()
.build();

String payload = APNS.newPayload().alertBody("Can't be simpler
than this!").build();
String token = "theTokenIsRemoveHere";
service.push(token, payload);

Here is the error:

Yes, it's got to be a PKCS#12, containing your APNS certificate along
with the private key.

.pem files generally are certificates only (no private key).

If you created the APNS cert on a Mac, you'll have to import the
certificate you got on the Apple portal into the Mac's KeyChain (or
something like that), and then export it and the private key as a P12.
