Summary

With a slew of advanced new features, ColdFusion MX 7 represents both an opportunity and a challenge for those developing Web apps with it. The opportunity, of course, lies in taking their applications to new and increasingly sophisticated levels. The challenge is digging deep enough into ColdFusion to discover the features and techniques that will take them there. In these pagesBen Fortaand the Macromedia team have made this information not only accessible but also easily digestible for intermediate and advanced ColdFusion developers. Users wonrs"t want to waste any time before getting down to the serious business of unraveling ColdFusionrs"s new features so that they can use Structured Business Reports to deliver business data in an understandable format; deploy the ColdFusion language in mobile phones and instant messaging clients; build rich, multistep data-entry forms; use Enterprise Manager to cluster multiple ColdFusion servers on a single machine; and more. Through step-by-step instructions and real-world examples, yours"ll learn how to do everything from create secure applications to employ Java components.
