What distinguishes this title is the clear-as-crystal perspective on what messaging is and how to implement various messaging architectures. This book is far from just a listing of JMS APIs. The author outlines basic messaging concepts, including synchronous and asynchronous processing, plus the publish/subscribe and point-to-point models of message distribution. Early working code examples show off basic message operations (like sending and receiving messages). Then it's on to a nicely packaged demo of using a message-driven bean from Enterprise JavaBeans 2.0. A notable section looks at the various available JMS message types (and when and how to use them).
The book then covers larger concepts like transactions and security in JMS and the issues that you'll need to consider when designing secure and reliable enterprise messaging systems. The author looks at ways to make sure your messaging code is as fast and reliable as it can be. (He walks the reader through scenarios in which message queues can fill up, and in one good example, shows how orders for an online store build up in the queue in one business day.) A discussion of administration tasks is followed by real advice and screen shots using BEA WebLogic Application Server 6.1, a popular choice for J2EE/JMS deployment.
Final chapters really excel at guiding the user in designing JMS applications by providing hypothetical case studies for no less than four separate scenarios. Using intranet, extranet, and high-volume Internet systems, these examples and the designs outlined here will ensure that you can correctly apply JMS to a wide variety of enterprise-class problems. A final listing of all JMS APIs rounds out this book.
Overall, Enterprise JMS Programming sets a high standard for any programming text with its stellar presentation style and clear code examples, which provide the best of theory backed up with practical advice. It's sure to be an extremely worthwhile resource for any developer facing a JMS project. --Richard Dragan

4.0 out of 5 stars
Generally excellent, but not consistent.,
By "aserinsky" (Singapore) - See all my reviews
This review is from: Enterprise JMS Programming (Professional Mindware) (Paperback)
I bought this as I needed a JMS reference that went beyond the spec and talked about design, deployment and management of JMS infrastructure. I was very impressed with everything I read until I dipped into Chapter 13 - specifically the four pages on improving client-side throughput through internal queueing. While this is an excellent idea, the example shows how to build a complicated and threading-heavy internal queue and dispatching mechanism and recommends that you use it to, er, put events onto the Swing event dispatcher's internal queue. Hmm.The book (commendably) sets out to give a full picture of how to design, build, deploy, secure, and manage a JMS-based messaging architecture. This means, however, that it's very noticeable when a topic is skimmed over. For example, the section on bridging two different vendors' JMS implementations has two pages of simple code and less than one page of discussion that fails to consider administration, security, or performance, despite the normally good coverage of these areas elsewhere. Nevertheless, I was mostly impressed with this book - it's just a pity that the high standards it sets itself aren't met consistently throughout the book. A second edition that discussed the example architectures in Part III in detail would be a truly excellent book, and would be relevant to all messaging products rather than just JMS.

2.0 out of 5 stars
Not a very good book, very inaccurate, misguided,

This review is from: Enterprise JMS Programming (Professional Mindware) (Paperback)
First of all, I had high hopes for this book, based on other comments. I can only imagine comments were done by inexperienced people who didn't know too much about actual details regarding low-level details, or didn't mind factual errors, preaching style and skimming of actual useful pieces (beyond simple code examples one can easily get from Sun's JMS tutorial page).
At first book seemed ok; first few chapters had proper introduction to JMS, at surface level. Too bad it never really got beyond the surface: usually author just listed things at high level ("you can do this and that for security") without even trying to get into concrete facts. Worse, when he did, much of the time "facts" were just plain wrong. Comments on UDP, for example, were utter gibberish, as anyone who has basic knowledge of IP networking protocols knows (even the acronym given was wrong). And this continued throughout the book. Writing style was also too preachy for me: most of "naturally"s and "obviously"s could (and should) have been left out; especially as often it's debatable if the statement following was even true. Check "performance tuning" tips for a good example on misguided tips that most experienced java developers nowadays would consider obsolete (for example, suggestions on aggressive object pooling and reusing, using final keyword). The final problem that I saw was that there were also a few typos (and/or cut'n paste errors): for example, in message definitions descriptions for fields were clearly cut'n pasted, as the stock quote message descriptions wouldn't otherwise make any sense. The reason for two stars is due to the fact that the code samples were usually ok still, and there were some useful tidbits from related subjects (like JCE samples).

5.0 out of 5 stars
Best JMS book I've read,

This review is from: Enterprise JMS Programming (Professional Mindware) (Paperback)
I have used JMS for about 2.5 years before I bought this book.There wasn't many books writing about JMS the first time I used JMS back in 2000. This book has a solid coverage of JMS and give you advice in designing an enterprise application using JMS. You can find samples of administration tasks for JMS Product from BEA Weblogic and iPlanet Message Queue. The only thing that I missed is the coverage of IBM MQ, which is the messaging infrastructure that I use. If you want to get a good understanding on designing JMS application, don't look further, buy this book, you won't regret your investment
