Homework 5
CS320, Fall 2004

Due: Tuesday, Nov 23

Please upload your files using the online turnin server. The files should include all the source code, documentation, and an HTML file hw5.html, which contains a link to your JSP page on the CS server. Note that file uploading will be disabled automatically after 11:59PM of the due date, so please turn in your work on time.

[Problem Description]

For this assignment, add a registration page to the  web calendar you developed in Homework 4 so a user can create an new account, and implement a custom tag <logout> so we can get rid of the last bit of scripting element from the application. Again, all features described in previous assignments must work; otherwise there will be a credit penalty of up to 30pt.
[Registration Page] (40pt)

In the registration page, ask the user to fill out a form for username, password, first name, last name, and email, as shown in the following example:



Retype password:

First Name (optional):

Last Name (optional):

Email (optional):

Your application should properly handle the following situations:
For each type of errors, output an error message and ask the user to re-enter the data. Note that validation of the input data should be implemented on the server side.
[Logout Tag] (20pt)

Implement a <logout> tag so that instead of using scriptlets as described in Homework 3, your logout code should look somewhat like the following:
<c:if test="${! empty param.logout}">
    <cal:logout />
    <c:redirect url="Login.jsp" />
