The current version of NetTeam Server uses JSP (Java Server Pages) technology and runs on Mac OS X Server and Linux:

Mac OS X Server 3.0 or above, where it runs on the bundled Apache, MySql and Tomcat services. Linux with Apache v4.1.x, Tomcat and MySql v4.x (or other databases subject to configuration).

This will soon be expanded to support Apache Tomcat on Win/MacOSX/Linux, with MySql or Microsoft SQL-Server databases. Later this year we will support jBoss on MaxOSX/Linux/Windows with MySql or Microsoft SQL-Server or Oracle.
