I would dispute Java being expensive.  It depends what you want it 
for.  If you need a high-end J2EE application then, yes, there are no 
free J2EE servers, but many applications (including a managed 
learning environment that I have built) can be built using standard 
J2SE which is free to download from the Sun website.

I run my application using servlets and JSP on the Apache Tomcat 
servlet container which is free and open source.  The only Java 
software that we've had to pay for is a JDBC database driver to 
connect to an SQL Server database (and depending on what database 
that you use, you can get those for free as well).

> And did I mention slow?

For applets and Swing applications, yes, but for a web based 
application any slowdown negligable and is absorbed by normal network 
speed, even on our intranet.  Once a servlet is compiled (on the 
fly), and run for the first time, it will then stay in memory and 
actually quite fast (although I've got no objective stats to back 
that up).
