Default Websphere App server starting problem

Hi,

I am trying to experiment with MBeans in WAS 5.0.2.4.

After stopping the server using the command

$AdminControl stopServer server1

the fails to restart. When I try to restart the server using the console, I get the following error message in the System.out.log

ADMN0005E: Unable to activate MBean: type JMXConnector, collaborator com.ibm.ws.management.collaborator.DefaultRuntimeC ollaborator@6bac2d2b, configuration id RMIConnector, descriptor null.

Is it a configuration problem?

Thanks in advance for any help on this !!!
