The book is great. I was reading it a few weeks ago and really enjoyed it. Most probably we SHOULD encourage parctical programmers to WRIET more books like this. The book I've read before this one (I don't even remember the name) was so boring and ABSTRACT that I didn't even finish the first chapter. This one, though, is pretty down to earht and practical. Thumbs up!
This is a very good introductory book on java message service. This book is has a very nice and light reading. Nevertheless you are presented with a very complete approach to the specification. Furthermore you are warned for different architectures pros and cons for all of them. Queue and topics are discussed in a very productive way. You JMS on J2EE is discussed as well as JMS on spring. The only one downside of the book is some degree of repetitiveness on some of the contents. On an overall perspective we must say that this is a good technical book as is norma with O'Reilly
This book on JMS does a decent job of introducing Java messaging and has good sample code. Where it falls short is in the places where JMS itself falls short. It glosses over JMS shortcomings and doesn't say much at all on approaches one might take to work around them.
Even so, it's a good introduction and worthwhile for anyone who needs to learn about JMS.
