Java Programming: Advanced topics - Sample code

Hi,

I am trying to get a Java Bean sample code from Java Programming:
Advanced topics book working.
I have modified the code for SQL Server, it does not work??

The Java Virtual Machine throws a "could not find the main class"????
Could anyone point out what I am doing wrong.

I can get a db connection in a JSP page, am trying to create a
container that I can call the
variable from the JSP page.

Thanks for your help.
