JWIRC grounded on Java technology of Sun Microsystems. JWIRC is a small java IRC Applet working from the web page. The applet is multi-channels programm which consequently allows you to have a conversation through several channels at once. The irc applet does not limit you at number of channels. It is possible due to good optimization of memory usage . Users can send and recive files by DCC.
This soft is shareware, you may download ZIPeed pack with irc applet, documentation, examples, and setup it at your site. But remember that is a shareware soft will work (on client's side) only 5 minutes and then will continue operation, but with the locking of send message. For removal of this limitation you should register and receive the key from me. Also you can test without any limitations the irc applet from this site, just typing in the field named IRC Server name or IP address of your ircd server or any public server.
