使用JavaPNS向iPhone发送推送通知时出错？

Question

我正在使用javaPNS_2.2。将推送通知消息发送到iPhone设备的jar文件

我的代码是：

PushNotificationPayload payload = PushNotificationPayload.complex();

/* Customize the payload */ 
payload.addAlert("Hello World!");
payload.addCustomDictionary("mykey1", "My Value 1");
payload.addCustomDictionary("mykey2", 2);

/* Push your custom payload */
String keystore = "C:/1.0Eywa_Baba/PushNotificationKey.p12";
String password = "Eywa@12";
boolean production = false;
String devices = "C81DD339-F5C1-529F-BEC4-6C8622BA0BFD";
List<PushedNotification> notifications = Push.payload(payload, 
                                                      keystore, 
                                                      password, 
                                                      production, 
                                                      devices);

但是，我得到了一个错误：

log4j:WARN No appenders could be found for logger (javapns.notification.Payload).
log4j:WARN Please initialize the log4j system properly.
