 The Cart servlet must react by displaying the content of the shopping cart. The display should be tabular with one item per row. The table columns display the number, name, and price of each item in a read-only fashion. In addition, there should be a writable column for the desired quantity and a read-only one for the extended price. The display should also indicate a total, PST and GST (based on Ontario), a shipping cost ($5 that is waived for orders of $100 or more before taxes), and a grand total. The page has three buttons: Update (to refresh the calculated fields after editing a quantity), Continue Shopping, and Checkout. Notice that if the entered quantity of an item is zero then it should be removed from the cart. You need to also handle the case of negative or non-numeric quantities. The Cart servlet must react by displaying the content of the shopping cart.

 +==== Use Case: A client logs in ====
 +Upon checkout or at anytime, a login form (normally transmitted over https) is served prompting for the client name, shipping address, and payment details. We are not going to switch to https in this project. Instead, we will continue to use http and we will assume that all clients have already established accounts with the Company, i.e. each client has a profile that contains the shipping address and payment preferences. Hence, the login form prompts only for the client's account number and password.

-Upon checkout, the servlet must normally switch to https and prompt for the client name, shipping address, and payment details. We are not going to do that for this project. Instead, we will continue to use http and we will assume that all clients have already established accounts with the Company, i.e. each client has a profile that contains the shipping address and payment preferences. Hence, we will serve a login screen that displays the total amount and prompts for the client's account number and password. Upon authentication (based on accounts.txt) a confirmation screen is displayed to indicate that the P/O has been accepted and to provide a URL that the client can visit at any time to view the created P/O. See the next use case for details.+Upon checkout, the controller must ensure the client is logged in and must then display a confirmation screen followed by an acknowledgement that the the order has been accepted and is being processed. A URL that the client can visit at any time to view the created P/O must also be provided. See the next use case for details. 
  
 ==== Use Case: A client visits the URL of a P/O ==== ==== Use Case: A client visits the URL of a P/O ====
-Upon confirmation of a P/O, the system stores its content in an XML file based on the PO.xsd schema. The name of the P/O file is derived from the account number of the client and the P/O number (a per-client serial number that starts at 1). For example, the URL of the 3rd P/O of account number 1234B555, is: http://red.cse.yorku.ca:port/eFnnnnnn/po1234B55503.xml. Since this is an XML file, it needs to be transformed to XHTML before the client can see it. You can do this at the server or (preferably) at the client side. Note that this use case does not involve authentication.+Upon confirmation of a P/O, the system stores its content in an XML file based on the PO.xsd schema.

 In addition to the above use cases, it is recommended that your site supports the following uses: the ability to view the shopping cart from the catalog screen (i.e. without having to add an item); the ability to checkout from the catalog screen; the ability to cancel an order from the login screen. In addition to the above use cases, it is recommended that your site supports the following uses: the ability to view the shopping cart from the catalog screen (i.e. without having to add an item); the ability to checkout from the catalog screen; the ability to cancel an order from the login screen.

   - Design: Describe your system's architecture and data flow briefly (diagrams are ideal here). Also, several design issues and decisions must have popped up during the analysis and design phases, e.g. MVC, namespaces, file formats, algorithms, representations, etc. Describe in this sections the key issues and decisions that were made and why they were made the way they did.    - Design: Describe your system's architecture and data flow briefly (diagrams are ideal here).

The former discusses how the project was tested and the latter lists each and every limitation or shortcoming of the finished webapp with respect to requirement. 
-  - The Team: Provide the cs# and name of each member of the team and indicate the contact person in case there are questions. It is essential that you explain how the work was divided and how was communication and consistency maintained.+  - The Team: Provide the cs# and name of each member of the team and indicate the contact person in case there are questions.

    - Printouts: Include printouts of the XML order file as it appears on disk and on the client's browser and a printout of the completed procurement report showing the chosen wholesaler and price per item.    - Printouts: Include printouts of the XML order file as it appears on disk and on the client's browser and a printout of the completed procurement report showing the chosen wholesaler and price per item.
-   - The Source Code:  Provide listing of all programs (including jspx). Partition this section into subsections, provide a title for each, and create an entry in the Report's TOC for each subsection. Make sure the code is properly formatted. Some editors do not format properly because they use spaces instead of tabs and/or use proportional fonts. Do not delay printing your code to the last minute; resolve this issue early on. +   - The Source Code:  Provide listing of all programs (including jspx, tags, xsl, web.xml, etc.).
