org.javaWebGen
Class FrameworkController

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          org.javaWebGen.FrameworkController

All Implemented Interfaces:

java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class FrameworkController
extends javax.servlet.http.HttpServlet

Main application Servlet Controller is a traffic controller that calls on classes that implement the WebController class to do all the work. Someday I will get around to changing it to a filter. This class should be removed. It was used a dynamic class loader like the Ruby on Rails framework. I think this is a bad idea allowing a url to determine directly what class it can call! Instead it is safer to declare the URL to WebController mapping in an XML ahead of time.
