Java & APNS

It might seem to be very painful at first but it's pretty simple at the end...

We'll need some Java APNS library (for example https://github.com/notnoop/java-apns )

Generate new certificate for APNS in iOS developer center. Then download it and import certificate into your KeyChain on Mac OS X.

From KeyChain (on MaxOS X), find certificate and private key. Select and export BOTH of them as *.p12 file.

Use them with your code as simple as:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

//snippet of code used for testing puposes String certificate = "certificates/ServerCertificateProd2015.p12";Mode mode = Mode.PRODUCTION; byte[] bytes = IOUtils.toByteArray(Connection.class.getClassLoader().getResourceAsStream(certificate)); String password = "Your P12 Password"; ApnsServiceBuilder apnsServiceBuilder = APNS .newService() .withCert(new ByteArrayInputStream(bytes), password); if(mode == Mode.DEVELOPMENT) { apnsServiceBuilder.withSandboxDestination(); } else { apnsServiceBuilder.withProductionDestination(); } ApnsService apnsService = apnsServiceBuilder.build(); PayloadBuilder payloadBuilder = APNS.newPayload(); payloadBuilder.badge(1).alertBody("Hello"); String builtApns = payloadBuilder.build(); apnsService.push("YOUR_DEVICE_TOKEN", builtApns);
