SSLHandshakeException unknown_ca apns java


SSLHandshakeException unknown_ca apns java



I am trying to implement a standalone application for iphone; for which I wish to use Apple Push notification for iphone clients. I am getting javax.net.ssl.SSLHandshakeException: Received fatal alert: unknown_ca Following is my Java code to connect to apns gateway:

int port = 2195; String hostname = "gateway.sandbox.push.apple.com"; char[] passwKey = "password".toCharArray();  KeyStore ts = KeyStore.getInstance("PKCS12"); ts.load(new FileInputStream("/path/to/file/Cert.p12"), passwKey); KeyManagerFactory tmf = KeyManagerFactory.getInstance("SunX509"); tmf.init(ts, passwKey);  SSLContext sslContext = SSLContext.getInstance("TLS"); sslContext.init(tmf.getKeyManagers(), null, null); SSLSocketFactory factory = sslContext.getSocketFactory();  SSLSocket socket = (SSLSocket) factory.createSocket(hostname,port);  String[] suites = socket.getSupportedCipherSuites(); socket.setEnabledCipherSuites(suites); //start handshake socket.startHandshake(); 

Please help me understand what and how the ssl certificate can be installed on my Linux machine.

EDIT :

It worked for me now, I recreated Cert.p12, and the program started working. I don't know what was the exact cause for not working, but I guess it would be corrupt Cert.p12 file.

Thank you all for your help.

You may need to add the certificate to your jre's cacerts file (generally located under lib/security).

Look into the documentation for keytool and its -import option for more information.
