public abstract class UserServlet

extends HtmlServlet

An extension of HtmlServlet for creating servlets which can be run only by authenticated users. UserServlet works identically to HtmlServlet, with the additional guarantee that HtmlServlet.doGetOrPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.http.HttpSession, java.util.Map, java.io.PrintWriter) will be called only if a session exists and is owned by an authenticated user.

Method Summary

void	doGet(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) Handles the HTTP GET request by calling HtmlServlet.doGetOrPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.http.HttpSession, java.util.Map, java.io.PrintWriter).
void	doPost(javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) Handles the HTTP POST request by calling doGet(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse), thus ensuring that GET requests are handled identically to POST requests.

           throws javax.servlet.ServletException,
                  java.io.IOException

Description copied from class: HtmlServlet

Handles the HTTP GET request by calling HtmlServlet.doGetOrPost(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, javax.servlet.http.HttpSession, java.util.Map, java.io.PrintWriter). Also displays any exceptions that may be thrown by doGetOrPost.

(This method is called by the server, and should not be called by servlet code. Most servlets can leave this method as-is, but some may need to override it.)

Overrides:

doGet in class HtmlServlet

Parameters:

request - a HttpServletRequest object encapsulating this browser request.

response - a HttpServletResponse object encapsulating the servlet's response.

javax.servlet.ServletException

java.io.IOException

                   javax.servlet.http.HttpServletResponse response)
            throws javax.servlet.ServletException,
                   java.io.IOException

Handles the HTTP POST request by calling doGet(javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse), thus ensuring that GET requests are handled identically to POST requests.
