In general, the page (view) should access data placed in either the application, request, page, or session scope by the Action class. It is considered a "best practice" for the Action class to act as a proxy to your business tier. For example, the Action class would leverage the appropriate business beans to process the data. The Action class would be responsible for placing the results of the processing (if any) in the appropriate scope.
The servlet, in the data transport diagram below, represents the front controller or Struts ActionServlet, and therefore it is not directly responsible for placing the data in the respective scope, but rather delegates HTTP requests to the appropriate Action class and forwards to the appropriate view. robert > -----Original Message----- > From: Agrawal, Rajeev [mailto:[EMAIL PROTECTED]] > Sent: Monday, July 22, 2002 11:17 AM > To: '[EMAIL PROTECTED]' > Subject: Populating view from Web tier? > > > I have been reading some documentation on Struts.
