JMX Remote and MBeans in separate Processes

Question

Hi,
I found on Sun blogs - http://blogs.sun.com/jmxetc/entry/what_is_jmx
following:
"An EJB lives in an Application Server container. It usually implements business logic. An MBean lives in an MBeanServer, and usually implements management logic"
That means, when an MBeanServer is killed, an MBeans dont't run anymore?
I have several Java applications.
I want use the JMX to manage (remote) this applications (start, stop, status watch) I created one MBean for every application and registered them on an MBeanServer. I can now start, stop application and observe the status.
public interface AdapterMBean {
String getStatus();
void start();
void stop();
But when I kill the process of MBeanServer, my applications don't run anymore.
Method start() starts application in new Thread.
Can JMX fulfil this requirement, that an MBeanServer runs in its own process and MBeans run in separate processes (now on the same machine)?
If yes, what shoul I do?
thanx
Peter

PeterWhen you kill a process, you kill all its execution threads.
A thread is not a process. It runs within a process.
If you want your applications to remain alive when you kill
the process that started them you need to start them in a
new separate process. See System.exec().
The question is: why do you kill the process that runs all your
applications in the first place?
Are you sure you are doing what you want to do?
