Assignment 4

This assignment will give you practice with writing servlets. In this assignment, you will create an on-line store selling something, and use servlets to register customers, track purchases and customer accounts.

The assignment is fairly open-ended. At the very minimum, we are going to look for the following features:

• Your site should provide for "registration", where a customer can create a username and password, enter address information and be assigned an account. You can do this right up front or during the "checkout" process.
• Your site should provide at least five different products, along with prices and descriptions. Customers should be able to purchase more than one item during a visit. It should be possible to add items to a shopping cart.
• Provide a checkout procedure that allows a customer to verify what they have committed to purchase before finalizing the purchase.
• Only registered customers should be able to purchase.
• Registered customers should be able to view their account status.
• Other rules:
  • Your webpages should consist only of standard HTML. They should NOT contain Javascript, for example.
  • For the backend, use only servlets. You may NOT use PHP or any other such backend language.
  • Use simple files as your database.

Apart from technical correctness, points will also be awarded for originality, creativity, usefulness and humor.

To get started:

• Under SimpleWebServerJar/webroot/ create a folder (directory) called a4html.
• In this directory, make a simple HTML file called home.html. So, the URL to access this will be:

  
      http://unix.seas.gwu.edu:40013/a4html/home.html
      

  (Using your port number).
• We will assume that the file home.html be the starting point for your website.
• Under SimpleWebServerJar/servlets/ create a folder (directory) called a4servlets.
• Write a servlet called A4Servlet.java in the a4servlets. directory. For now, just to get started, simply write something to the browser, just like you did in the HelloWorld servlet. Compile it.
• Edit the servlet.properties file to add A4Servlet.java by adding the line:

  
      servlet.A4Servlet.code=/servlets/a4servlets/A4Servlet
      

• Then run java Serve in the usual way and access the HTML file with

  
      http://unix.seas.gwu.edu:40013/a4html/home.html
      

  Similarly, access the servlet using URL

  
      http://unix.seas.gwu.edu:40013/servlets/a4servlets/A4Servlet
      

• This is where you should implement your servlet code and of course call this from the "form" tags of your HTML.
• The direct access of the servlet from the browser is only to get started and to make sure the folder structure is working. After that, you will only access home.html and from there, your servlets will generate the remaining HTML.

Deliverables and submission:

• You will upload three zip files:
  1. The first, called a4html.zip, will be a zip of your HTML in the a4html directory. This is all the HTML for your assignment.
  2. The second, called a4servlets.zip, will be a zip of all your servlets in the a4servlets directory.
  3. The third, called a4.zip should contain a single HTML file called a4.html and various images. When we open a4.html we should see various screenshots showing that you accomplished the assignment.
• We will test by unpacking your zip files in the right places and will use your port number.
• NOTE: (1) you must write ALL your servlet code. (2) All your website code must be written using Java servlets. (3) Apart from the standard libraries, you may not use any other Java code. Nor can you use CSS, Javascript, PHP or any other web technology.
• You must use your assigned port number.
