Package com.jcorporate.expresso.services.validation Description

This package provides for a 'validation framework'. This framework is provided for a specific group of problems described as follows:

1. User enters some information to perform some sort of action, let's say to unsubscribe from a mail list.
   
   
2. The validation framework then sends a confirmation email to the user that includes a clickable URL. This URL contains a 128-bit random number.
   
   
3. The user clicks on the random number. The framework then looks up that random number and dispatches the request to the appropriate ValidationHandler class.
   
   
4. The validation handler then performs the appropriate actions and displays the final message to the user.

You can see this system in action in Expresso's registration system in: com.jcorporate.expresso.services.controller.RegistrationController
