This book provides an excellent overview of the core Enterprise Java technologies for building 3 & N-tier application servers. Though it does not go into too much depth, it did provide enough information (sample code sniplets) and understanding of how each of these technologies play within a distributed OO application service - JMS, JTS, EJB, JavaServerPages, Servlets, and JDBC.

Each chapter provides useful information about the technology and its role in an enterprise application.

Although there are many sources that will provide you with the same kinds of information on JMS, JTS, EJB, ... this book is a very nice single source reference for all these technologies.

If you are new to Enterprise Java or simply need an overview of how all these technologies play together in a distributed intra/internet application server - this is a good book to start with.

There are a lot of books on the markets these days on J2EE, so finding what you what can be daunting. What this book offers is a good introduction or foundation to the Java Enterprise Technologies. It would be useful for any Java programmer/developer who wants to learn about these technologies but does not know where to begin. So if you do not know your JNDI's from your RMI's, your EJB's from your JMS's, your JSP's from your Servlets, or your JTS from your JTA's, then I would recommend this book for you.

It covers the most important Java APIs that the enterprise developer who uses Java.

The books covers JDBC, RMI, JNDI, JTS, JMS, JSP, EJB, and a few other technologies. The book tends to alternate between explanatory and example chapters. So first, JDBC is discussed and then the next chapter walks through an example.

Given the number of topics in this book, each topic is not covered in full detail as most of the topics are worthy of a book all their own (and many of them already have one). However, this book's goal is to cover just enough so you can understand the technology and get started using its core features.

Therefore, this makes the book excellent for trying to figure what these technologies do. In fact, this book is readable by managers as well as developers, if the managers skip the example chapters.

From reading this book, you get the impression that the authors have quite a bit of experience, have used the technologies discussed, and know what they are talking about. On the whole, this is a great book for getting your feet wet with Enterprise Java.

The authors try to give some good coverage of Java enterprise applications but they examples are as old as "java.awt.swing.*" classes.

Need to debug the examples to make them run on on Java 2 platform. The emphasis is also on printing debugging statements. (An additional debugger class for most of the examples).

It is time authors updated the contents of the book or reduced the price.

I spent a couple of hours in the bookshop checking out all EJB books. I'm pretty convinced this is one of best. It gives a good overview of all important Java Enterprise APIs.

Sometimes rehashing the APIs, but it only for completeness and clarity. The examples are short but clear, although often they only change 1 line compared to a previous example, luckily the important things are in bold.

Good overview, good tutorial. Nice job.

The content presented in the book is very impressive but the examples are so outdated that this book is useful for "Theory of Enterprise applications".

The price for this book is simply outrageous for the outdated examples (oops! minus theory)

There are so many book out there, which focus on a particular technology. Very few books explain each technology and show how to integrate them all. This book does that, and explains how to integrate and put to use Servlets, JSP, Beans, EJB, RMI in a single application. Writing a book on a particular technology may not be easy, but writing a book which integrates these technologies, and shows how in the application these can be integrated is not a easy job either. I would love to see more CORBA integration in its second edition, with emphasis on CorbaBeans.

May be it's personal but I believe that those who are not geeks of their professions - shouldn't
teach others as well. If you're not fascinated by the topic you talk about - how do you expect
to write a good book ?! I think that this book was written by someone who learned Enterprise Java
just to pay his rent. Writing a book seemed just another possible income ..

Why do I think so ?

Well, topics are explained on the very primitive level and I can actually "smell" that authors
just don't know the material good enough to dig in - they repeat the same basic ideas many times
but leave lot's of questions unanswered (like "Why do some methods in this table return a variable
of a primitive type and others their object wrappers ? Is it just typo or something else ?"),
their code examples take pages but contain only couple of useful (and, again, trivial) lines and ..
typos everywhere (make up your mind already - is it "javax.naming" or "java.naming" ?).

Whatever I look at - I see Java dilettantes, not Java geeks and not even Java professionals
(excuse me, but one who compares two Strings for equality using compareTo() instead of equals()
doesn't have a clue about Java for me !).

I think it is still useful for getting the idea about major J2EE technologies (JDBC, JNDI, servlets,
JSP, RMI, EJB, JMS and JTA) but *on the very basic level*. That's what I keep it for.

P.S.
The title should be changed to "Developing Java Enterprise Applications *for dummies*" because
authors DO treat their readers like a 14-year old kiddies - "type <something> and press ENTER".
Folks, who do you think you're talking to in this book that you need to remind me about pressing ENTER ?

For the most part, I agree with the other reviews here. I just want to add something I'm suprised others left out - the author is no writer! Sometimes you have to read a sentence several times to understand what it really means, and even then some guessing is usually involved.

From the time this book was first published it seems that not many people appreciated it. That is probably because it is not a Wrox Press-style treatise on how to build full-blown professional Java enterprise programs. Instead it is a sampler of all of the various Java enterprise technologies, complete with small programs that show how to use the various API's. It starts out answering such simple questions as What is enterprise development? and Why use Java for enterprise development? It then devotes a chapter or two each to introducing the reader to the various enterprise API's - JDBC for database control, the JNDI for managing objects in a directory, server-side programming with servlets, JSP, and JavaBeans, managing remote objects with RMI and Corba, the basics of XML, creating and sending email using JavaMail, and much more. None of the chapters is intended to make you an industrial-strength Java enterprise programmer. The intention is just to give you an idea of what all of the individual technologies and packages can do via short programming examples so that you are ready to tackle the Wrox Press J2EE books of the world. The one bad point of the book is that it is in dire need of an update via a 3rd edition that I think will probably never come due to the lack of success this book ultimately had in the realm of total sales. However, if you are comfortable with Java and want to get a taste of what the enterprise API's can do I think it is still a good investment, particularly at the very low used prices at which it is currently available.
