A simple persons profle system that I wrote in JSP and XML that will retrieve the name and age of the person that is being stored in XML file. The code is very short and easy to understand perfect for beginners in Java Servers Pages or JSP programming.
In this program I am using Java EE IDE provided freely by Eclipse.org and Apache Tomcat as my application server. I hope you will find my work useful in learning web programming using Java Server Pages or JSP.
If you have some questions please send me an email at jakerpomperada@gmail.comand jakerpomperada@yahoo.com.
