Spot on. *Web development* is actually a misnomer. I prefer 'web 
interface'. The 'OO'ness of something shouldn't depend on the user 
interface. An OO system encapsulates the human concepts of 'business' 
and 'system' and presents (or should present) an end user interface 
agnostic facade to any client that might want to use it.

In the classic [simplified] three tier web application we have a browser 
who's responsibility is to interface with a human being, a 'bit in the 
middle' who's responsibility it is to implement the business logic (for 
want of a better term) and some mechanism to persist important data.

The application executing on the bit in the middle is the thing we are 
interested in. Whether it is 'OO' or not has nothing to do with a 
particular interface.

FWIW

Way back when, I worked for a training company. My job was to develop 
their Java training offering. One of my courses focused on the early 
J2EE offering with particular focus on EJB. I used an early release of 
Weblogic and built a CD containing everything required to run the labs.

I developed a collection of DOS batch files and Unix shell scripts that 
automated the installation and configuration of the app server and it's 
dependencies. The student would insert the disk, click the relevant 
script file and in less than 2 minutes everything was up and running.

Make no mistake, this was heavy on the OO aspect of software engineering 
with plenty of opportunity to delve into the darker corners of the 
language. It worked a treat and I used and developed it over a period of 
two years. I still have the CD somewhere... wonder if it still works?
