yeah, sorry about that you should be able to get it here: http://anonsvn.jboss.org/repos/jbosstools/trunk/documentation/guides/GettingStartedGuide/en-US/database.zip

Its a mistake that the link is absolute to the svn location and not simply relative to the documentation location. Being looked into for the next update.

I thought that was fixed:
