1. Create a web application called "estore"
2. The webapp should be accessed by http://localhost:8080/estore. This means you should make sure that appropriate welcome file is configured. Use welcome file list concept.
3. The application should be built on JSF technology. Please refrain from using JSP pages for building pages, instead use xhtml for building pages.
4. Any 404 errors should go in to a customized error page
5. Every page should have a header section on the top reflecting the company name and heading of the page.
6. Every page should have a footer section at the bottom reflecting the copyright and contact information.
7. The main page should give some basic information about the company and have 4 links

Insert a new item
This should take the user to a page that will allow the user to add an item in the item table. The form should allow the users to enter appropriate values, and then submit the form. The resulting page should be a confirmation page or same page indicating the error messages. In this assignment the errors can be caused because all values were not entered in the form, or cost price and selling price is not a float, or quantity on hand is negative or nonnumeric. In the future, the errors may be caused due to database anomalies, but let's not worry about that now. The form should take in all the fields mentioned in the "Item" table below.

Update the price of an existing item
This should take the user to a page that will allow the user to update the price of an item. The form should allow the users to enter appropriate values, and then submit the form. The resulting page should be a confirmation page or curent page indicating the error message. The form should take in an item number and a new price, and update the price of the item.

List all items
This should take the user to a page that will list all the items in a table with headings.

Buy an item
This should take the user to a page that will allow the user to buy an item. The form should allow the users to enter appropriate values, and then submit the form. The resulting page should be a confirmation page or an error page indicating the error message. The form should have item number, quantity to buy, customer last name, customer first name, customer street, city and state as fields. Errors should be reported if all the values are not entered, or values invalid, or if the item does not exist.

8. All pages should have a link to the home page.
9. Here is link to a zip file that contains java file templates for backend logic. estore_interfaces.zip
10. Note that there is no actual database or file persistence as part of this assignment. Persistence will be the next assignment. But you are expected to persist data in memory. So as you are running the appliation, the backend logic should commit all item objects to memory.
