我有推送通知的问题。我有一个由团队成员创建的p.12证书，并且具有要推送到设备的设备令牌。我正在使用javapns库来做推送(也尝试了同样的结果的javaapns lib)，但是我不断得到这个错误：

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

这是我用来测试的代码

try {

List n = Push.combined(text, 20, null, file, "********", false, token);

for (PushedNotification notification : n) {

if (notification.isSuccessful()) {

System.out.println("Push notification sent successfully to: " +

notification.getDevice().getToken());

} else {

String invalidToken = notification.getDevice().getToken();

Exception theProblem = notification.getException();

theProblem.printStackTrace();

ResponsePacket theErrorResponse = notification.getResponse();

if (theErrorResponse != null) {

System.out.println(theErrorResponse.getMessage());

}

}

}

}

catch (CommunicationException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (KeystoreException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

我阅读并尝试了其他几个帖子的建议，包括将证书导入到cacerts密钥库中，但导入失败。我正在开发使用eclipse在windows机器上。

任何熟悉这个问题的人？我是新来使用ssl，所以也许我做错了，是不是我不能使用在另一台机器上生成的证书？
