Question

我是JMX的新手。我需要创建一个自定义JMX客户端，它将连接到远程服务器并从mbeans读取数据。

这是我到目前为止的应用代码：

String url = "service:jmx:rmi:///jndi/rmi://host:port/jmxrmi";
JMXServiceURL serviceURL = new JMXServiceURL(url);
Map env = new HashMap();
String[] creds = { "role", "password" };
env.put(JMXConnector.CREDENTIALS, creds);
JMXConnector cc = JMXConnectorFactory.connect(serviceURL, env);
MBeanServerConnection mbsc = cc.getMBeanServerConnection();

当我启动我的应用程序时，我收到以下错误（已修改为添加完整堆栈跟踪）：

任何帮助都将不胜感激。

问题在于客户端密钥库中缺少服务器证书。
