public class Invoker
extends javax.servlet.http.HttpServlet

Dynamic Servlet Invoker. This servlet invokes anonymous servlets that have not been defined in the web.xml or by other means. The first element of the pathInfo of a request passed to the envoker is treated as a servlet name for an existing servlet, or as a class name of a new servlet. This servlet is normally mapped to /servlet/* This servlet support the following initParams:

  nonContextServlets       If false, the invoker can only load
                           servlets from the contexts classloader.
                           This is false by default and setting this
                           to true may have security implications.

  verbose                  If true, log dynamic loads

  *                        All other parameters are copied to the
                           each dynamic servlet as init parameters
