Comments on EJB 3 in action, by Debu Panda, Reza Rahman, Derek Lane

On the bright side, the text is most of the times crystal clear, easy to understand and follow the code creation from scratch. The helpful appendix of the book guides the reader to setup the Sun Glassfish application server in minutes, without any trouble. Such easiness really tempts to switch your java integrated development environment (IDE ) to Sun Netbeans. The database scripts given are for Oracle though, not for Derby. The source code of the book runs correctly out of the box with only an exception as mentioned here:
http://www.manning-sandbox.com/thread.jspa?threadID=37203&tstart=0
Apart from Glassfish, there are also many code versions, suitable for the older Oracle Application Server (oc4j),JBoss and weblogic 10.
On the dark side, the text is IDE neutral, the deployment is done using ant scripts. Many spelling errors also appeared in the text and the huge errata page at Manning site.
All in all, the book is highly recommended, I am looking forward to reading its newer, updated edition!

Comments on Heads first Servlets&Jsp 2nd Edition


On the bright side, the book is written in an unusual way, full of graphics and photos of an oriental martial arts movie, in an attempt to make reading the text, seem like fun. The book is full of exercises and questions to help the reader to memorize whatever is important for passing the exams. The text is clear, easy to understand most of the times, with the exceptions of the chapter about patterns and custom tag development. There also many typographical errors in the text and the questions as well. One should consult the huge error page at O'Reilly.
On the dark side, there is no hands on coding practice, the examples mentioned are deliberately simple, about cats and dogs, or outdated (struts) so that you can not easily reuse any source code from the book. This is no reference book either, as stated by its authors.
All in all, the book prepares you well for the Sun J2EE 1.4 exams, servlet v2.4, jsp v2.0, in a straightforward and funny way, but it certainly needed a greater update on older themes and addition of newer, such as jsf.

Comments on Getting Started With Oracle SOA Suite11g, Heidi Buelow Manas Deb Jayaram Kasi Demed L'Her Prasen Palvankar


On the bright side, the text is very well written with so few spelling errors. Its tutorial form guides the reader smoothly, one step at a time. The majority of the chapters are short and concrete, the text is easy to understand and to follow, most of the times. It surely serves the reader well, as a hands on introduction, without getting deep into details. Its source code works!
On the dark side, the installation chapter, 4, needs some additions, clarifications and updates, since the newer versions always need patching and so on. The download links from o.t.n. also need an update. An inexperienced reader might spend a considerable amount of time and effort to get the SOA suite servers up and running. These two links could offer some significant help: http://forums.oracle.com/forums/thread.jspa?messageID=4210625&#4210625 and http://www.packtpub.com/article/installation-configuration-oracle-soa-suite-11g-1
All in all, the book offers a clear introduction in SOA and is recommended as a primer for newcomers to the SOA 11g world. An experienced soa 11g user might consider the book superficial, as no mention is made of advanced subjects, such as creating XML schema and reusing it.
