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 The IBM product, WebSphere Studio Site Developer has been replaced by IBM Rational Web Developer.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 some of the screen captures 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>We apologize that the WSSD Trial supplied with the book, no longer has a valid license. If you have any questions or problems while working through the examples in the book, please post them here.
