SOLUTION

• The doGet() method in the example extracts values of the parameter’s type and number by using request.getParameter().
• The servlet is called PersonQueryServlet, while the form specifies that “action=”PersonQuery”.”
• The Web server must be told that this servlet is to be used to handle requests for PersonQuery.
• The form specifies that the HTTP get mechanism is used for transmitting parameters.
• So the doGet() method of the servlet, as defined in the code, is invoked.
• It uses these values to run a query against a database.
• The code used to access the database and to get attribute values from the query result is not shown.
