使用Javapns苹果推送通知服务 [英] Apple Push Notification Service using Javapns

问题描述

我用下面的code发送通知到苹果通知服务器。

I'm using the following code to send notification to the Apple Notification Server.

import javapns.Push;
import javapns.communication.exceptions.CommunicationException;
import javapns.communication.exceptions.KeystoreException;

public class APN 
{
   public static void main(String[] args) {
        try {
            Push.alert("Hello World!", "keystore.p12", "mypassword", false, "myDeviceIdentifier");
        } 
        catch (CommunicationException e) {
           e.printStackTrace();
        } 
        catch (KeystoreException e) {
            e.printStackTrace();
        }
   }
}

推荐答案

信息的关键部分是：

java.net.ConnectException：操作超时

java.net.ConnectException: Operation timed out

您一定要运行此code中的服务器可以连接到苹果服务器APN端口上指定？

Are you sure the server running this code can connect to the apple apn server on the port you specified?

提示：使用Telnet来验证

Hint: use telnet to verify.
