[Shailesh Barde]

  
I have to update the resource bundle from an Action Class.I found it impossible 
as the handle of Resource Bundle is with ActionServlet when it is 
intialized.So, in order to update the resource Bundle values i have remove the 
handle first.
My Question is it true?If Yes why & if No how it can be done?

Please guide..
