Your IT department is building a lightweight Front Controller servlet that invokes an application logic objectwith the interface：public interface ApplicationController {public String invoke（HttpServletRequest request）}The return value of this method indicates a symbolic name of the next view. From this name， the FrontController servlet looks up the JSP URL in a configuration table. This URL might be an absolute path or apath relative to the current request.
