Denise & Charles, I found the tutorial at:
http://www.ibm.com/developerworks When you get there, on the left, click on "Java Technology", then click on "Education". In the list that comes up, you'll see a tutorial titled: "Introduction to JavaServer Pages technology" That's the one I was going through. There are a lot of other neat tutorials there as well.
