"All Struts actions begin with a URL that is submitted to the JSP request object when the end user clicks a Struts-defined link. The link must be of the form actionPathName.do, where the extension .do causes the ActionServlet to locate the corresponding action in the struts-config.xml configuration file.
The runtime process for handling actions in the Struts framework implemented by the BC4J component tags is:
1. User clicks a link that submits a .do parameter.
2. ActionServlet maps the request URI to the Action class through the definition in struts-config.xml.
3. The action class processes the request through a method implementation."
