There is a problem with the licensing for the software that comes with the book. The IBM product, WebSphere Studio Site Developer has been replaced by IBM Rational Web Developer. The look and feel is very similar between these products. Most of the changes correspond to the difference in the level of Eclipse that the tools are built upon. <p>Although the step-by-step (exact menu sequences, etc.) will differ slightly between these two tools, you should be able to build and work through the book's exercises using the trial version of IBM Rational Web Developer: <a href="http://www-128.ibm.com/developerworks/downloads/r/rwd/?S_TACT=105AGX28&S_CMP=TRIALS">http://www-128.ibm.com/developerworks/downloads/r/rwd/?S_TACT=105AGX28&S_CMP=TRIALS</a> <p>The Project Interchange files that appear on the book's CD can be imported into the Web Developer v6 in the same way as described to bring the projects into WSSD. <p>We apologize that the WSSD Trial supplied with the book, no longer has a valid license.
