JSP, Bean and Servlet

[Bob Tanner <tanner@real-time.com>]

Read an interesting article in JavaPro about Presentation, Model and
Controller design pattern (think this is it, left the mag at home).

Anyways, it talks about using JSP as the presenation, a Java Bean as Model and
Servlet's as the controller.

JSP's get their info from the Bean for display on the web.

Servlet's manipulate the info on the Bean.

The Bean just sits there and holds the data. :-)

I understand the JSP can POST/GET to the servlet, that communication channel is
clear.

I also understand how JSP can retrieve data from the Bean. The Bean is
instantiated inside the JSP, so that is simple.

What I don't understand is how does the Servlet communicate with the Bean?
