I was wondering if someone could recommend a good
client ( WITH SOURCE CODE) for wildfire. I would
prefer VB6 or Java
I would suggest Coccinella ( http://hem.fyristorg.com/matben/ ). Although this Jabber client is not written in one of the languages you mention, it is the only open-source client that support the Asterisk-IM extension for Wildfire ( http://jivesoftware.org/asterisk-im/clients.jsp ). Support for AIX, Jingle (what Google Talk uses), SIP, Zoep, and TIPICs voice chat protocol are planned or in process.
so I can customize my client to my
environment (graphics, icons, logo etc…).
I know that the author of Coccinella is open to do that for you for some money. Besides that Coccinella has support for themes (this is improved in the development version).
