I put my webapp on a vitual host ,it has originally installed rails with  
the version of 1.1.4, however recently it has upgraded rails to the  
latest 1.2.3 and my webapp has used rails-engine and can not be  
restarted, can i use rails 1.1.4 for my app alone and how to do that?  
Bow!

It is still useless when i set RAILS\_GEM\_VERSION=‘1.1.6’ in  
environment.rb  
ps: the version 1.1.6 of rails still exist on the host.
