為什么我收到錯誤&拒絕與JMX的連接-魔扣目錄

本文介紹了為什么我收到錯誤&拒絕與JMX的連接的處理方法，對大家解決問題具有一定的參考價值，需要的朋友們下面隨著小編來一起學習吧！

問題描述

我無法連接到JMX對象。下面是我如何創建一個JMX對象：

public static void main(String... args) {
    MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
    try {
        ObjectName name = new ObjectName("org.javasimon.jmx.example:type=Simon");
        if (mbs.isRegistered(name)) {
            mbs.unregisterMBean(name);
        }
        SimonManagerMXBean simonManagerMXBean = new SimonManagerMXBeanImpl(SimonManager.manager());
        mbs.registerMBean(simonManagerMXBean, name);
        System.out.println("SimonManagerMXBean registerd under name: "+name);

    } catch (JMException e) {
        System.out.println("SimonManagerMXBean registration failed!
"+e);
    }

    while (true) {
        // waiting for connections
    }
}

這是用于連接到遠程JMX對象的代碼：

JMXServiceURL url = new JMXServiceURL("service:jmx:rmi://127.0.0.1:9999/jndi/rmi://127.0.0.1:1099/jmxrmi");
JMXConnector jmxc = JMXConnectorFactory.connect(url, null);
MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();
SimonManagerMXBean simonManagerMXBean = JMX.newMXBeanProxy(mbsc, new ObjectName("org.javasimon.jmx.example:type=Simon"), SimonManagerMXBean.class);
return simonManagerMXBean;

很遺憾，我收到以下錯誤：

如果我嘗試使用”jconsole”實用程序連接到我的JMX服務器(作為本地進程)，我首先會收到”ConnectionFailedSSL1″錯誤，但當我在錯誤表單中單擊”Insecure”按鈕時，我連接成功。

服務器和客戶端位于同一臺計算機上。

我使用的是Windows 7 x64。Windows防火墻已禁用。
