JBuddy Messenger

From Zion Software, LLC:

JBuddy Messenger is a cross-service, cross-platform IM client for J2SE compliant Java enabled PCs, Macs and devices. JBuddy Messenger supports AIM, ICQ, MSN Messenger and Yahoo Messenger on all the major operating systems including Windows 98, NT, 2000, XP, Mac OS X, Linux, Solaris, OS/2, etc. In addition to supporting the major public IM services, JBuddy Messenger supports Zion's enterprise IM solution - JBuddy Message Server.

Future enhancements of JBuddy Messenger are already in development to provide a rich set of enterprise IM features. JBuddy Messenger is available as a free demo download. Standard Install Anywhere installer is used. Since JBuddy Messenger stores preferences locally and makes network connections to other computers (AIM, ICQ, MSN, Yahoo, ZionSoftware.com for new version checks and mini-ads) unrestricted access is necessary to use this IM client. Our jars have been signed with a Thawte Code Certificate for your protection. We have a commercial version called JBuddy Messenger Pro which includes support for Jabber and Lotus Instant Messenger (Sametime). Please visit Zion's store page for licensing information.
