Query: Don't waste YOUR Money

It's an outdated book covering 1.5 version (ver 3.0 soon to be realesed). It can be best described as a cut & paste operation from the Silverstream manuals. That too version 1.5 manuals!I know currently this is the ONLY book available in the market but better wait a month or so and buy the NEW book that's being published by SilverStream Journal (check it by using the LINK on www.silverstream.com)
