public class Invoker
extends 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

Method Detail

init

public void init()

Description copied from class: GenericServlet

A convenience method which can be overridden so that there's no need to call super.init(config).

Instead of overriding GenericServlet.init(ServletConfig), simply override this method and it will be called by GenericServlet.init(ServletConfig config). The ServletConfig object can still be retrieved via GenericServlet.getServletConfig().

Overrides:

init in class GenericServlet

service

protected void service(HttpServletRequest request,
           HttpServletResponse response)
                throws ServletException,
                       java.io.IOException

Description copied from class: HttpServlet

Receives standard HTTP requests from the public service method and dispatches them to the doXXX methods defined in this class. This method is an HTTP-specific version of the Servlet.service(javax.servlet.ServletRequest, javax.servlet.ServletResponse) method. There's no need to override this method.

Overrides:

service in class HttpServlet

Parameters:

request - the HttpServletRequest object that contains the request the client made of the servlet

response - the HttpServletResponse object that contains the response the servlet returns to the client

Throws:

ServletException - if the HTTP request cannot be handled

java.io.IOException - if an input or output error occurs while the servlet is handling the HTTP request
