Enterprise System Java Programming

Objectives

This assessment item relates to the unit learning outcomes as in the unit descriptors. It is worth

40% of the total marks for the unit. The project in this document let you apply the enterprise

application design skills that you learn in MITS5502 by creating a Product Maintenance

application that lets users add, update, and delete the product records that are available to the

application.

NOTE: The solutions of the first two parts are given to you to give you a general idea of what you

are expected to do. Make sure you read the description of each part and try to do the first two parts

even though the solutions are given.

An Introduction to the Project

The Project is divided into six smaller parts that each part builds upon the previous parts. Each

Project part should take about 1.5 hours to complete.

Project parts General description and tasks Weightage

Part_1 Solution provided 0%

How to develop the Project

The description of each Project part includes images that show how the pages should appear in a

browser, a general description of the operation of the project’s pages, and some general

specifications for how the project should be coded. This information is detailed enough for you

to complete the project. However, you will need to determine any unspecified details on your

own. For example, you will need to create your own names for the servlet and JSP files that you

create, you will need to determine what error messages to display when the user enters invalid

data, and so on.

Unless you’re instructed otherwise, you can implement each Project using any programming

techniques you wish. In some cases, however, the project’s specifications will direct you to use a

specific programming technique. In that case, you should implement the project as directed.

NOTE: Make sure you take screenshots of each step as well as output results and paste them

into “studentIDMITS5502.doc” with appropriate heading. Your Project will not be marked if this

word document is missing.

What to Submit

(1) A root folder “studentIDMITS5502_Project” containing:

(A) “studentIDMITS5502.doc”

(B) The Project folders

i. Part_1

ii. Part_2

iii. Part_3 (and your codes to complete this Part)

iv. Part_4 (and your codes to complete this Part)

v. Part_5 (and your codes to complete this Part)

vi. Part_6 (and your codes to complete this Part)

(2) Your responses to each Project part should be in the form of a written essay (use the temple

given on Moodle) which includes:

(A) Front page

(B) TOC

(C) Header and footer

(D) Explanation and screenshot of all steps involved in the Project application (code,

all output tests including reports, IDE project structure … etc.). Make sure you put

all in each appropriate heading according to the TOC.

(E) Used references

(F) The name of the Word document should be “studentIDMITS5502.doc”

You are required to zip the root folder (1) for submission via Moodle by the due date.

NOTE: Your Project will not be marked if any one of the 2 items above is missing.

The Project The following pages present the user interface, operation, and specifications for each project. As

you view these pages, remember that each part builds upon the previous parts.

Part_1: Product Maintenance (solution given)

For this part, you’ll create a series of pages that allow you to add, update, or delete a product that’s

available to the application.

The Index page

The Products page

The Product page

The Confirm Delete page

Operation

(1) When the application starts, it displays the Index page. This page contains a link that leads to the Products page that can be used to add, update, or delete products.

(2) To add a new product, the user selects the Add Product button. This displays the Product page with all text fields empty. Then, the user can fill in the text fields and click on the Update Product

button to add the product.

(3) To edit an existing product, the user selects the Edit link for the product. This displays the Product page with all existing data for the product displayed. Then, the user can edit any entries

and click on the Update Product button to update the data for the existing product.

(4) To delete a product, the user selects the Delete link for the product. This displays the Confirm Delete page. Then, if the user confirms the deletion by selecting the Yes button, the product is

deleted and the Products page is displayed to reflect the new data. If the user selects the No

button, the Products page is displayed.

Specifications

(1) Use a Product class like the one shown later in this document to store the product data.

(2) Use a ProductIO class like the one shown later in this document to read and write the product data

to a text file named products.txt in the WEB-INF directory.

(3) Use a text file like the products.txt file shown later in this document as a starting point for the

products that are available to the application.

(4) Use server-side validation to validate all user entries. In particular, make sure the user enters a code,

description, and price for each product. In addition, make sure the product’s price is a valid double

value.

(5) If possible, get the Product.java, ProductIO.java, and product.txt files from your instructor or

trainer. Otherwise, you can create these files yourself.
