Query: J2EE 1.4 joke book

The authors used J2EE 1.4 first beta as their reference, with current beta 2 release most chapters gone obsolete right away. The authors also forgot the point Weblogic and Websphere does not implement j2ee 1.4. This is an obsolete bible! The official release of j2ee 1.4 spec is 6 months away. Don't waste your money.
