How to unregister mbean

[vadims]

I am registering a user session mbean with the MBeanExporter usging the following code at runtime:

MBeanExporter mBeanExporter =
(MBeanExporter) appContext.getBean("mBeanExporter");

String objectName =
"com.company.product:userSession=" + userSession.getId();
mBeanExporter.registerManagedResource(userSessionM Bean,
ObjectName.getInstance(objectName));

When user session ends (user logs out), I'd like to unregister the the mbean, so that it disappears from the JMX console.

Is there a way in Spring to unregister an mbean at runtime? Is the only way to unregister an mbean at runtime to get an explicit reference to MBeanServer?

I believe that is the only way. That's one of the uses of the *MBeanServerFactoryBean.
