Java APNS（蘋果推送通知服務）錯誤

我想使用Java APNS - 一個開源項目 - 向iPhones發送推送通知。雖然我收到了一個錯誤。Java APNS（蘋果推送通知服務）錯誤

我已經使用.pem文件作爲證書。這應該是一個.p12文件嗎？我不確定它們有什麼不同，但是我在網上的某處看到這些文件格式存在差異。

下面是代碼：

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);

這裏是錯誤：
