Please look into the Tomcat examples from apache. Tomcat IS the Servlet2.2
Reference Implementation. It has a great varieties of servlet and JSP examples
with source. Tomcat3.2B1 is really easy to install on both Linux and NT or
Win2K! Setup documentation is inside the tar/zip file. Hunter's book could also
help you!
