quartz使用jmx报ClassNotFoundException

Question

Quartz启用jmx，启动注册成功，但客户端连接时报错
server：
org.quartz.scheduler.jmx.export = true
org.quartz.scheduler.jmx.objectName = jmxBean:name=task
org.quartz.scheduler.rmi.export = true
org.quartz.scheduler.rmi.registryHost = 192.168.1.1
org.quartz.scheduler.rmi.registryPort = 1099
org.quartz.scheduler.rmi.createRegistry = as_needed
org.quartz.scheduler.rmi.bindName = TaskInfo

client:
public static void main(String[] args) throws Exception {
  String rmiUrl = "service:jmx:rmi:///jndi/rmi://192.168.1.1:1099/TaskInfo";
  String cfgTaskId = "1000";
  System.out.println(rmiUrl);
  System.out.println(cfgTaskId);
  System.setSecurityManager (new RMISecurityManager() {
   public void checkConnect (String host, int port) {}
   public void checkConnect (String host, int port, Object context) {}
  });

  JMXServiceURL url = new JMXServiceURL(rmiUrl);

        JMXConnector jmxc = JMXConnectorFactory.connect(url,null);

        MBeanServerConnection mbsc = jmxc.getMBeanServerConnection();      

        ObjectName mbeanName = new ObjectName("jmxBean:name=task");   
       
 }
 
报错如下：
