J2EE has become required knowledge for any serious Java developer, but learning this large and complex specification requires a substantial investment of time and energy. Sams Teach Yourself J2EE in 21 Days, 2/E presents the enterprise Java architecture in accessible, easy-to-comprehend lessons, describing how each J2EE tool solves the challenges of n-Tier development. Using the architecture as a roadmap, chapters describe Enterprise JavaBeans (EJB), JavaServer Pages (JSP), Java Servlets, and more, giving readers a full understanding of J2EE development.

Further chapters cover the role of XML, custom JSP tags, creating J2EE Web Services, and how Java Connectors allow J2EE applications to interact with legacy and non-Java systems. The book finishes with sample applications which put all the pieces together, including an example using J2EE to create Web Services. Along the way, every concept is illustrated with practical, real-world examples to ensure understanding by Java students as well as experts.

Explains nothing - 2007-12-12

I am a (software development) middle manager with a background as a C programmer. Every 2-3 years I'll buy 1 book + products to try to stay relatively current with industry evolution. I bought VB 4.0 & MS Access and was able to use the VB 4.0 documentation alone to build a fairly elaborate application. I bought Borland JDeveloper & Oracle and with the help of Teach Yourself Java in 21 days was able to migrate my application to (i.e. rewrite my application for) Java/Oracle. Now I acquired J2EE from Sun and mySQL with a view to migrating the same application, bought this book, and find that this book is of absolutely no help whatsoever. This book is reliant on downloadable samples (which are now out-of-date and unusuable) and fails to explain what I want: nuts-and-bolts construction of a "Hello World" type program where I hand-craft a JSP, a servlet, a session bean and an entity bean using the mySQL database (which I had up and running within 1 hour of download) to extract the "Hello" and the "World" from 2 separate columns in a database table, and hand-craft the deployment descriptors needed to package & deploy the application.

This book is shelved. When I figure out what I want to learn from other sources, I'm inclined to try to write an alternative text to recoup my wasted $50+.

At Day 2 you come to a screeching halt - 2007-06-21

The book and the code you download from Sam's website is based on a Pointbase embedded database, but Java J2EE now comes with a Derby database, so you aren't able to create and install your database. I suppose this book would work as a reference manual for some things, but you definitely won't be able to teach yourself much.

Book was in great condition, and cheap $4.75.
I'll buy book from them all day long for that price lol.
I would recommend buying from this seller!

The most complete Java2EE book - 2007-09-10
Reviewer Rating:
This book covers a wide range of key points in the Java2EE technology, very complete reference for begginers and advanced programmers.

Terrible book - 2007-03-28
Reviewer Rating:
The different authors write different chapters defining some things differently.

The material is outdated, you'll constantly have to update their junk to make it work.

Way too verbose and bouncing back and forth within an individual chapter (just try those two early BMP/CMP chapters).

It's just not worth $1.

Use the sun tutorials for a much better and much much clearer start.
