Struts Controller Components (cont'd)

• The controller receives all requests and decides which action to take on the basis of the request's action attribute.
• Each action request is mapped to an Action class that does the work of esponding to the request.
• Mappings are made in the struts-config.xml file. Here are the action-mappings elements in struts-config.xml for the banking application
• Note that the login action is mapped to the LoginAction class in the banking application
• Note that action elements also set "forwarding" actions in the case of login success or failure
