GlassRoom is a user-friendly web-based Java chat system with multi-threaded chat servers providing stable, high-performance and HTTP tunnelled communication.

One of the standout features of GlassRoom is its very easy installation process, which is available on Windows and Linux. The software is installed on Windows as a service, meaning it stays permanently on your system. For Unix systems, there is a wrapper Perl script that makes installation and running easy.
GlassRoom's chat applet is easy to use, nice looking, and incredibly powerful, with specially designed GUI components that make it work with all versions of Java – including old Java 1.1 through Java 1.4. Communication is facilitated using HTTP-tunneling technology, which makes it possible to chat even behind firewalls. The chat server itself is extra stable, and rarely requires restarting.
Additional capabilities include logging and remote administration, the ability for moderator users to ban a user's IP address, flood control to prevent users from sending bothersome messages, the ability for users to create new rooms easily, quick reloading of applet and images, and a 'chat watch' feature that replaces noise words in messages.
Overall, GlassRoom is an excellent choice for anyone looking for a high-quality, feature-rich chat system that's easy to use and install.
