Online School Registration Java Servlet

///////////////////////////////////////////////////////////////////////////
//Title: Online Registration Servlet
//Author: Steven Jacobs
//Dev. Tools: JBuilder3..JDK 1.2
//Description: This is a mock-up version of an online registration servlet
//    for any university. It is similar to an online family reservation
//    servlet I created about 7 months ago. I thought I would take about
//    an hour to do this and share it with you. Maybe you can get
//    something out of it. Please improve.
