This article demonstrates how to use Allaire's XML serialization technique, Web Distributed Data eXchange (WDDX [described at www.wddx.org]), to transfer CFML data structures from the server to the client, and into JavaScript and back. Generally WDDX's approach is to interchange ... (more)

This article focuses on some interesting features of ColdFusion 4.5 and server-side Java. Introduced in ColdFusion 4 (and greatly extended in 4.5), the CF Server supports Java by providing three ways to access server-side Java with ColdFusion. (We're not talking about client-side... (more)

This article demonstrates how to write a paired custom tag that encapsulates complex DHTML logic into a simple-to-use tag. I was inspired to write by Tim Buntel's article about DHTML wrappers in CFDJ (Vol. 2, issue 4). It motivated me to extend a custom tag I had developed and us... (more)

During a recent intranet project, I encountered the need for live reports of all currently open user sessions within an application. The goal was for me to be able to see how many users were currently online with an open session when rolling out new templates from the development ... (more)
