I developed a little application (web application) using JavaEE+MySql. I try to keep some data and .. from time to time to get some reports using my data.

My problem is I have to access this application from 4-5 computers in the office. They are connected through a switch. It's a typical small office network, nothing fancy.

I need some advice on how to do this. I mean for a small application with no external communication is it mandatory to use an Apache machine?

I'd use a simple Tomcat container on the "server machine" (which is my computer, a windows machine) and .. basically .. I would like to permit the access to my colleagues also.

I don't have any knowledge about concurrency (I know mysql permits concurrent access) so I would like some configuration tips also.
