pardon me for this silly question…but still i would
like to know ,isnt wildfire the latest version of
jive messenger??
Yes. Messenger was renamed to Wildfire when version 2.4.0 was released.
isnt wildfire just the server side software??
Yes.
if i install wildfire alone will i able to chat with
other users??
Mostly yes. Since Wildfire is server side software you’'ll also need a client that users can use to communicate with each other.
if i need to perform chat between two users dont i
need to install a client side software like
spark,smack or exodus??
Yes for Spark and Exodus; I would of course recommend Spark. Smack isn’'t a client, rather it is a XMPP/Jabber Java API used for developing client side applications.
