GlassRoom is a user-friendly web-based chat system built on Java with a reliable multi-threaded chat server, HTTP tunneling, and an attractive interface resulting in high performance.

Installation is a breeze with GlassRoom, as it is installed on Windows as a service, and stays permanently on your system. On Unix systems, there is a wrapper perl script that streamlines installation and running.
The chat applet itself is user-friendly, nice-looking, powerful, and flexible. Furthermore, GlassRoom uses HTTP-tunneling technology to communicate behind firewalls, ensuring wider accessibility.
The chat server is extra stable, so there's no need to restart over long periods of time – even months or years! Logging and remote administration capabilities add to the convenience of the system, as does the ability for moderator users to ban a user's IP address.
Flood controlling prevents users from sending bothersome messages many times quickly, and the creation of new rooms is a simple process. The applet and images can be quickly reloaded, and "chat watch" capability replaces noise words in messages.
On the technical side, the server is implemented using Java Servlet technology, and the GUI components are specially designed to make the chat applet more attractive and work with all versions of Java, including old Java 1.1 through Java 1.4.
Overall, GlassRoom is an excellent choice for web-based chat, offering a wealth of capabilities, flexibility, and reliability.
