Google Talk integration with Java

Sharing is Caring

Hello All

Google Talk is most popular chat client that uses your Gmail login authentication, and after this tutorial, you will be able to create your own Gtalk (if you use swing ), this tutorial shows how to integrate Gtalk with Java.

This example uses Smack API, Smack is an Open Source XMPP (Jabber) client library for instant messaging and presence. A pure Java library, it can be embedded into your applications to create anything from a full XMPP client to simple XMPP integrations such as sending notification messages and presence-enabling devices.
