我無法連接到JMX對象。這是我如何創建一個JMX對象：爲什麼我得到錯誤「連接被拒絕」與JMX
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!\n"+e);
}
while (true) {
// waiting for connections
}
}
這是連接到遠程JMX對象代碼：
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;
可惜的是我收到以下錯誤：

如果我嘗試使用「jconsole」實用程序連接到我的JMX服務器（對於本地進程），我首先得到「ConnectionFailedSSL1」錯誤，但是當我在錯誤表單中單擊「不安全」按鈕時，我成功連接。
服務器和客戶端都在同一臺計算機上。
我正在使用Windows 7 x64。 Windows防火牆被禁用。
我是否需要在客戶端或服務器端添加此設置？ –

它的工作原理。謝謝。正確的端口號是1099. –
