All Implemented Interfaces:

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

public class EchoServlet
extends javax.servlet.http.HttpServlet

Method Detail

doGet

public void doGet(javax.servlet.http.HttpServletRequest request,
         javax.servlet.http.HttpServletResponse response)
           throws javax.servlet.ServletException,
                  java.io.IOException

Generates the response via HTTP GET.

Overrides:

doGet in class javax.servlet.http.HttpServlet

Parameters:

request - HTTP request

response - HTTP response

Throws:

javax.servlet.ServletException - Error indication

java.io.IOException - Error indication

doPost

public void doPost(javax.servlet.http.HttpServletRequest request,
          javax.servlet.http.HttpServletResponse response)
            throws javax.servlet.ServletException,
                   java.io.IOException

Generates the response via HTTP POST.

Different from the doGet() method since the data is also written to the log file to be able to debug the payload sent by web forms, HTTP POST clients etc. since these often do not process the response data in an appropriate way.

Overrides:

doPost in class javax.servlet.http.HttpServlet

Parameters:

request - HTTP request

response - HTTP response

Throws:

javax.servlet.ServletException - Error indication

java.io.IOException - Error indication
