Execute a method with JMX without JConsole

Question

How to execute a method with JMX without JConsole?

I want to invoke methods through JMX from Java code. With the code below I can get the name of all methods of the MBean interface but I am not yet able to actually execute them. Something is still missing, could anybody please help me?

private static String connectJmx() {
    StringBuilder sb = new StringBuilder();

    JMXServiceURL serviceUrl;
    JMXConnector jmxConnector = null;
    try {
        serviceUrl = new JMXServiceURL(URL);
        jmxConnector = JMXConnectorFactory.connect(serviceUrl, null);
        MBeanServerConnection mbeanConn = jmxConnector.getMBeanServerConnection();

        ObjectName objectName = ObjectNameProvider.getObjectName();
        MBeanInfo info = mbeanConn.getMBeanInfo(objectName);

        MBeanOperationInfo[] operations = info.getOperations();         
        for (int i = 0; i < operations.length; i++) {
         sb.append(operations[i].getName()).append("\n");
        }

    }
    catch (Exception e) {
        LogManager.doLog(LOG, LOGLEVEL.INFO, "exception connection jmx",  e);

    } finally {
        try {
            if(jmxConnector != null){
                jmxConnector.close();
            }
        } catch (IOException e) {
        //
        }
    }       
    return sb.toString();
}

The for cycle above collects the names of the methods. I want something similar, that instead of collecting the names, actually executes them. Please do not recommend JConsole, it does not work for other reasons.

You have not put the code to invoke an mbean method. Here is a sample code to help you with that:

import javax.management.*;
import javax.management.remote.*;
import com.sun.messaging.AdminConnectionFactory;
import com.sun.messaging.jms.management.server.*;


public class  InvokeOp
  { 
    public static void  main (String[]  args)
      { 
        try
          { //  Create administration connection factory
                AdminConnectionFactory  acf = new AdminConnectionFactory();

            //  Get JMX connector, supplying user name and password
                JMXConnector  jmxc = acf.createConnection("AliBaba", "sesame");

            //  Get MBean server connection
                MBeanServerConnection  mbsc = jmxc.getMBeanServerConnection();

            //  Create object name
                ObjectName  serviceConfigName = MQObjectName.createServiceConfig("jms");

            //  Invoke operation
                mbsc.invoke(serviceConfigName, ServiceOperations.PAUSE, null, null);

            //  Close JMX connector
                jmxc.close();
          }

        catch (Exception  e)
          { System.out.println( "Exception occurred: " + e.toString() );
            e.printStackTrace();
          }
      }
  }
