I have just come across the jdom product thru an article on www.onjava.com
at http://www.onjava.com/pub/a/onjava/2000/12/15/xslt_servlets.html.  I
have made some changes the servlet and class.  I am also using my own XSL.
When I run my servlet(code below) I get the following error:

java.lang.ClassNotFoundException: class JDomServlet2 :

        Document doc = ci.getDocument();

This is my first attempt at using XML,XSL,XSLT,JDOM, etc. any help would be
greatly appreciated.

Thanks,
