If you want to add AJAX to the magic collection of buzzwords supported by your Web site (and who can resist the siren call of the latest buzzword?), then you have two major options: purchase a proprietary package or experiment with open source libraries.
InfoWorld has covered a number of excellent proprietary AJAX toolkits in the past, and now we’re turning our attention to some of their open source rivals. Are they worth exploring for enterprise use?
In his article Peter examined these toolkits : Dojo, Google Web Toolkit, Microsoft Atlas, Open Rico, Yahoo AJAX Library, Zimbra Kabuki AJAX Toolkit
