JAVA (Applet) Source Code for Instant Messaging

HI

Can anyone help me?

I have spent the last 3 hours searching online for a simple and direct Source Code for JAVA Instant Messaging.

I have downloaded a great deal of ZIP files, of Source Code (such as Smarck, Shigeoka, PJIRC, etc) but still have not found what I am looking for.

I need to implement an Instant Messaging (IM) feature into my company’s web application server, to enable employees and/or offsite consultants to communicate in REAL-TIME (in other words, ONE-ON-ONE Instant Messaging).

Does anyone have an idea of where I can find a suitable code for this?

Thanks
