Google Talk Client in Java2Script
Google Talk (also known as Gtalk) is Google's instant commnunications service. There are already 3 official Google Talk copies:
- Google Talk Client (Windows only, written in C or C++)
- Google Talk Gadget (For all modern browsers that support Flash, platform independent)
- Google Talk Web (Integrated with GMail, for all browsers that support JavaScript)
Here is a pure JavaScript copy of Google Talk Client from WeBuzz.IM. It is first implemented in Java language using Eclipse SWT and Smack (A library for Jabber's XMPP). Then the client is converted to JavaScript with servlet supports. And then it's deployed on a Tomcat server. As Java being platform-independent, and JavaScript is browser-independent, this Google Talk client runs in any modern browsers, such as Firefox, Opera, and Internet Explorer (IE), on Windows, Linux, Mac and others OS platforms. For more details or architectural information, please visit blog "Inside Java2Script".
To use or test this Google Talk client, please login with your account or given default account, and chat with your friends as what you previously do in official version of Google Talk Client. You will find out that this Google Talk client has the same layout, dialos, menus and operations with the official one. Have your feels and funs.
From testing we can tell that Microsoft's Internet Explorer (IE) is a lot slower than Firefox or Opera for this JavaScript copy of Google Talk. For your experience of instant communications, we recomend you visit this page by Firefox or Google Chrome.
Besides web Google Talk, WeBuzz.IM also supports web Windows Live Messenger, web Yahoo! Messenger, web AOL Messenger, web ICQ and web Facebook Chat.
And you can download WeBuzz.IM this offline web messenger from http://webuzz.im/downloads.html. You can also download the early version of Gtalk desktop client - google-talk-j2s-1.0.0-src.zip. To deploy Java2Script Google Talk to your Java servlet container, we recommend you to following Tutorial of Java2Script SWT and Simple RPC Application.
