Background documentation Accessing MBeans Locate the document in its SAP Library structure

If a management client only wants to invoke a single operation or access a single attribute on a MBean, it typically accesses the MBeanServer directly:

Example

import javax.management.MBeanServerConnection;

import javax.management.ObjectName;

...

MBeanServerConnection mbsc;

ObjectName name;

...

mbsc.setAttribute(name, new Attribute("Test", "test value"));

 

If the client does more interaction, the code will become difficult to understand. If the interface of the MBean is available to the class loader of the client, it could create a MBean proxy, which significantly simplifies the interaction with the MBean.

Example

// the management interface of the MBean

interface MyMBean {

  public String anOperation(String, Integer);

  public String setTest(String test);

  ...

}

 

import javax.management.MBeanServerConnection;

import javax.management.ObjectName;

import javax.management.MBeanServerInvocationHandler;

...

MBeanServerConnection mbsc;

ObjectName name;

...

// create the MBean proxy

MyMBean myMBean= (MyMBean) MBeanServerInvocationHandler.newProxyInstance(mbsc, name, MyMBean.class, false);

// invoke operations, access attributes

mbeanProxy.setTest(aValue);

mbeanProxy.anOperation(aValue, bValue);

 

For more information, see the API documentation of javax.management.MBeanServerInvocationHandler.
