Hello all,
There are three ways to look at the phrase "out dated".
First, HFS is a study guide for the SCWCD certification exam. The exam is still on the
servlet and
JSP specs for
J2EE v1.4. This exam will
not be updated for J2EE v1.5 (which is now called "Java EE v5"). This decision was made due to the fact that the servlet and JSP specs are not changing significantly for
Java EE v5. Therefore, from this perspective the HFS book is not outdated.
Second, HFS is an introduction to servlet and JSP technology. As such, specs change periodically and a book will naturally become outdated over time. However, as I just stated the serlvet and JSP specs for Java EE v5 will not be changed dramatically from the J2EE v1.4 version of these specs. Therefore, HFS will only be moderately outdated.
Lastly, HFS uses
Tomcat as the webapp deployment environment of choice. Open source implementations tend to evolve linearly over time (at least as long as the tool is useful). Therefore, the HFS book has gradually drifted out-of-date with Tomcat. Is that really significant? It is if our instructions for configuring Tomcat has become outdated. However, I suspect that there is little in HFS on Tomcat-specific information. If you want the latest and greatest on Tomcat, then HFS is not the book for you. I would recommend O'Reilly's
Tomcat -- The Definitive Guide or the online documentation.
Cheers,
Bryan
