I have installed Jive Messger on FC4 software. After that i have no idea how to configure. Could anybody help me how to configure server, add users etc., and what are client software to be used on both linux as well as windows machines.

If you have problems with it please point this.
There are plenty threads in Forum about clients. Try searching. Most of people will point you to this page:
