I found this book very useful for everyone who uses J2EE platform and has some existing applications in other technologies. The book gives in-depth overview of all possible approaches and technologies and the examples are good too. This book is for developers with some experience in J2EE and addresses some problems I couldn't find anywhere else.

What I found particularly useful was the EAI architecture, which shows how to develop Web Services in J2EE and how to connect them with existing applications. This is exactly what my problem was!

I bought this book after a long search to find out J2EE component examples for JMS, XML, J2EE Connectors and XA transactions. Ofcourse this book solved my EAI problems using J2EE components.

(+) Good examples on JMS, XML processing, J2EE connectors, JTA transactions and implementing custom security.
(-) Theory chapters discussing why J2EE.

Finally, It's a great book, worth reading for cut & paste EAI examples.

This book provides comprehensive coverage on integration of existing applications (not only legacy, but also Microsoft COM+, CORBA, SAP R/3, etc) with J2EE platform. It covers all relevant J2EE technologies including CORBA, Java Connector Architecture, RMI-IIOP, EJBs, JMS, XML and others with code examples (that actually seem to work). Two chapters are devoted to transactions and security. The book even touches B2B integration (SOAP and Web Services). But best of all, the book does not focus on technologies only but provides guidelines on integration process, particularly on evaluation of existing applications. Currently it is the only book on this topic. Highly recommended for every J2EE developer!

This book is one of those huge co-authored Wrox books which cover a broad area. In this case the topic is Enterprise Application Integration (EAI) - getting old and/or incompatible "legacy" systems to work together. As with many such books, the content varies in quality, detail and usefulness.

EAI is a tough area, and the overview and strategy sections are very good. From any other publisher they would be a separate book. The section on EAI process is almost as good, but it just presents a process with no discussion of shortcomings or alternatives.

The rest of the book is taken up with technical sections, mostly about the various J2EE APIs which can help an EAI project. It's in this area that the book is weakest. Some of the material is effectively redundant (the EJB, Servlet and JSP APIs are covered much better in many other books, for example) or lacks detail (the key area of client emulation and "screen scraping" gets lots of mentions but nothing about how to do it, etc.). In general this section of the book tends to gloss over the "hard stuff".

I was disappointed to find no bibliography or references for further reading. A book like this is just an introduction to the topic. You'll need to look elsewhere to actually make things work.

Despite the negative points, this is still a valiant attempt to cover a large, and often overlooked, area. If you are integrating legacy systems it's well worth the price.

The authors did a real good job focussing all the fundamentals of EAI and J2EE with solid examples.

This book has been very helpful for me especially to understand XML, JMS and distributed transactions using J2EE components. The examples are really cool. The book is very much targeted to BEA Weblogic users! I think so...!

Overall the chapters and examples are great and it is definitely worth a buy.

I bought this book, almost six months ago.

So far, this book helped me to implement couple of hard-core J2EE projects involving EJB, XML and JMS. I just reused the chapter example code provided with this book. It also enriched my skills in XML, JMS and EJBs particularly to learn messaging applications . It also helped me to chalk out the complete architecture and development process. I strongly recommend this book, who are in pursuit of implementing large scale J2EE projects.

I bought this book exactly two months ago. It helped me to solve many problems associated with my current EAI project. The examples provided works well with BEA Weblogic 6.1. Especially the chapters on JMS, XML and handling transactions were very heplfull.I do some books on EAI and J2EE. But those books did'nt cover well Integration. I would recommend to everyone who is especially involved in J2EE based integration projects.

The book's first chapter introduces eai and an overview of j2ee technologies.
Chapter 2 discusses choices and strategies when deciding on integrating applications. It can be quite dry and academic at times but worth reading. Many fundamental concepts are presented and provide the building blocks for the rest of the book. There is no real mention of j2ee or java in this chapter, the strategy is universal across different component models and architectures (j2ee, corba or .net).
There are chapters on ;
how j2ee could be used for eai.
when in the project to integrate.
what are the different techniques used to integrate.
How can xml and messaging be used for eai.
Modeling process using uml.
There are two chapters focusing on corba and rmi-iiop
Chapter 12 shows how to integrate using ejb. This also covers using ejb 2.0, message-driven beans and cmp 2.0. The reader should be familiar with ejb, cmp, bmp and the value object design pattern.
The book also has chapters on the j2ee connector architecture, windows com bridges, transaction management (ots, transaction api), security management, presentation and finally web services. The section on security and single sign-on is interesting.

This book is aimed at java developers with a few years experience. You will need good knowledge of java and some knowledge of xml, uml and component architectures (CORBA, ejb). If you need to understand how to integrate your new j2ee solution to use existing (legacy or otherwise) applications then this is a good book to read.

(+) Real world examples showing how to build EAI applications using JMS, J2EE Connector Architecture.
(+) Good code examples for J2EE-COM Integration, Distributed Transactions.
(-) First 4 Theory chapters, "JUST DON'T WORTH IT".

No decent EAI examples. Good for managers looking at using J2ee to integrate systems, offers ideas to some TA's, but little help to the seasoned developer. We already know what an EJB is...
