From http://java.sun.com/developer/technicalArticles/javaserverpages/servlets_jsp/

How Do JSP Pages Work?

A JSP page is basically a web page
with traditional HTML and bits of Java
code. The file extension of a JSP page
is .jsp rather than .html or .htm,
which tells the server that this page
requires special handling that will be
accomplished by a server extension or
a plug-in.

When a JSP page is called, it will be compiled (by the JSP engine) into a
Java servlet. At this point the
servlet is handled by the servlet
engine, just like any other servlet.
The servlet engine then loads the
servlet class (using a class loader)
and executes it to create dynamic HTML
to be sent to the browser, as shown in
Figure 1. The servlet creates any
necessary object, and writes any
object as a string to an output stream
to the browser.
