I've recently discovered a great presentation on the topic of J2EE integration with ColdFusion, created by Ben Forta:

Java and ColdFusion MX - The Marriage of Power and Productivity

This is perhaps the best presentation I've seen on the topic for both its content and presentation. Ben illustrates the technical highlights of ColdFusion in fluent manager-ese in a manner that is aimed at traditional Java audiences. The presentation itself is given in Macromedia Breeze, which can be loosely thought of as an enhanced PowerPoint with audio.
