Looking for a very basic tutorial on how to build a Java web app

I need to build a small web app (or desktop application, but since it was suggested that I use Tapestry BeanDisplay etc components, i'm seriously looking into the web app route)
Problem is, I have close to zero experience in this area (+a year or so in server-side programming in Java)

Will appreciate links to tutorials etc, as right now I'm not even sure of terms methods etc.

This will give you some background on web applications.

Thanks for the link.
What application server would you recommend I use?

Tomcat: http://tomcat.apache.org/download-60.cgi. You want the "Core" distribution. It comes with servlet and JSP examples.

Note that Tomcat is a web server and servlet container -so it can run Java web apps- but it is not a full JEE server - meaning it doesn't support EJBs, JMS and other such APIs.
