How to enable RMISecurityManager in Tomcat 6.0?

[Suman.P.S]

 
Hi,
 I am interested to know how to enable RMISecurityManager when Tomcat 6.0 is 
running as Windows service? My requirement is as follows:
 
  The RMIClient is running as a servlet and should connect to the RMIServer 
program running outside Tomcat.
 
 
Thanks,
Suman
