First some corrections to last month's column regarding NewAtlanta's free ColdFusion implementation, "BlueDragon", specifically the Linux version. As of version 6.2, distributions more current than RedHat 9, including Fedora Core 1/2/3, are indeed supported. Furthermore, configuration issues, particularly integrating BlueDragon with Apache, can be overcome through a thorough reading of the installation guide.
Since BlueDragon comes in a free version, let's consider another free tool for ColdFusion, the Eclipse plugin "cfeclipse". Eclipse is now the de facto Java IDE (60% now use it, according to onjava.com's 2004 survey), and is becoming more popular for other languages because of it's plug-in architecture. CFEclipse does not provide WYSIWYG editing, but if you also develop in Java, perhaps even custom ColdFusion tags, then Eclipse with CFEclipse really makes sense.
All the software you will need to get up and running with CFEclipse is available at the following sites:
