but having the option of running client side code in the same language 
is a plus...

one thing that servlets do that I haven't seen elsewhere is that you can 
have variables defined per servlet

this makes it easy to do things like count the number current users, 
implement database connection pooling etc...

I find that in php/perl etc I end up reading a lot of stuff from 
file/database that really doesn't change very often (esp config stuff) 
- and have to be much more careful to avoid race conditions.
