doPost

public final void doPost(javax.servlet.http.HttpServletRequest servletRequest,
                         javax.servlet.http.HttpServletResponse servletResponse)

Handles a POST Request to the servlet. This Deserializes the object in the supplied HttpServletRequest to class ServerRequest, then executes request.executeCommand(). If a exception occurs that the ServerRequest object does not catch, this class send the client back an ErrorResponse indicating the error. All requests are logged, as well as any ErrorResponses.

doPost in class javax.servlet.http.HttpServlet

doGet

protected final void doGet(javax.servlet.http.HttpServletRequest servletRequest,
                           javax.servlet.http.HttpServletResponse servletResponse)
                    throws javax.servlet.ServletException,
                           java.io.IOException

Handles a GET request to the servlet. This allows users to do a test through a webbrowser to see if they can connect to the Servlet. When users point their browsers to the Servlet's URL, they will see the data printed here. This is used for test purposes only.

Overrides:

doGet in class javax.servlet.http.HttpServlet

Throws:
