Description: DispatchAction is another useful built-in Struts Action. However you cannot use it as is. You will have to extend it to provide your own implementation.

6. When is the best time to validate input in Struts

9. How to prepopulate a form in Struts

By: Apache Foundation : 2008-09-20

Description: The simplest way to prepopulate a form is to have an Action whose sole purpose is to populate an ActionForm and forward to the servlet or JSP to render that form back to the client.
