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).
