J2EE Pattern implementing Classes in Struts

["Kommineni, Sateesh (IndSys)" <sa...@geind.ge.com>]

Hi All,
 
  Can we identify a one to one mapping between the J2EE Patterns and the classes which implement these patterns in Struts..

   I tried identifying the Patterns in the Presentation Tier . Let me know your thoughts.. 

  
  Intercepting Filters    ---  Classes Specified using the Plug-in tag in struts-config.xml 
  Front Controller        ---  Action Servlet 
  Context Object          ---   
  View Helper             ---  All the tag lib classes that comes with Struts
  Application Controller  ---  Request Processor and Action Classes as Targets
  Dispatcher              ---  Action Forward
  Composite View          ---  This won't be provided as such in the Framework, will be used in App
  Dispatcher View         ---  
                               One of them will be used depending on the context . If the Business 					 processing needs to be done in View Helpers use Dispatcher View 						 other wise use Service to Worker
  Service to Worker	  ---

Thanks in Advance
Sateesh
