Restarting the server

[ravi naik]

Hi all..
   
  I am using apache geronimo for My Intalio and Jsp integration....
   
  For every change in the source code i have to restart the server .
   
  and it takes long time.is there any option so that i can refresh the server 
and change in code are reflected in application for example like tomcat...
  and How much RAM is required for GEronimo ...
   
  Thanks In advance....
