ECT 433: Survey of Web Programming Technologies

Autumn 2003

Assignment 2

Using a bean

Due Monday October 6 before 11:30pm

Summary

For this assignment, you will use a Java bean that provides the logical calculation for running a simple currency conversion application.

Basic application

Download and study the starter folder for this assignment. This folder contains files to create the CurrencyConv bean and a demonstration JSP file (convert.jsp) that uses all of its functionality. We will review how this file works in class.

Develop a Web application that allows a user to specify the following:

• A monetary amount
• A currency that the specified amount is in
• A currency in which the user would like to know the equivalent amount

The program should then respond with the equivalent amount.

Additional specifications

• The application should minimize user errors such as allowing the user to select from possible currencies rather than typing in the name.
• The application should check for legal amounts and provide a helpful message if the amount is not valid.
• The application should report the result while also confirming the specified currencies and starting amount. Use the abbreviations to write out the conversion result.
• Provide some means for allowing the user to enter a new amounts and currencies for conversion.
• Call the initial access file convert.jsp.
• Use a unique name (e.g. a login id) to name your folder.

Submission

You should submit a zip file that includes the contents of your web application files. Use the assignment submission application on the Distance Learning Web site.

If you are completing this assignment with one other student, make sure both names are commented in all html and jsp files. Only one submission is needed.
