SPRINGFRAMEWORK
--------------------------------------------------------
 
 
*  client sends requests, fill forms.
*  Struts handle receive request. Call the facade.
   Passes pojos as arguments for the Facade or simple arguments (String, Long...).
   Example:
ClientFacade.updateClientInformation(ClientPojo)
or
ClientFacade.updateClientInformation(clientId, clientNewNameToUpdate);
 
 
*  Facade access 1 or more Service Managers (same as Session Beans in EJB)
   Passes pojos
 
* The service manager receives a POJO as argument or simple arguments (String, Long...).
  Calls DAO to update information passing always pojos.
 
* POJOS (ALMOST DOMAIN OBJECTS FLY THROUGH THE APPLICATION)
 
I would like to have some comments on this architecture.
Can you help me see it's weakness!!?
 

Really thanks
