Exercise 6: Servlet that Reads HTTP
Request Headers
due April 24
- Create a Servlet that extends HttpServlet.
- It should inside of its doGet method, create or retrieve the session
associated with the client request.
- Create a web-page that has the following HTML form in it.
- When the button submit is hit, it will invoke via GET method
your servlet. (it should store product name in session)
- When the button invalidate session is hit, it will invoke via
GET method your servlet. (it should invalidate session)
- When the button view previous choice is hit, it will invoke via
GET method your servlet. (it should then return the current product value stored in session ---if nothing there or no session should report it.)
- Servlet reacts as follows via reading parameters sent in the client's
request
- if submit button was hit, it will read in the value associated
with the textbox and store this as a new product ordered. (replacing old value of product if currently one exists in the session)
- if invalidate session button was hit, it will invalidate the
session associated with the request.
