Summary: Not as deep as some, but great value for money
Review: One of the seemingly endless "in a Nutshell" series from O'Reilly, this book follows the basic series format. A few chapters of concise introduction followed by a detailed, if compressed, API reference. In this case the book covers a lot of ground - all the Java APIs which form part of the Java 2 Enterprise Edition: JDBC, RMI, CORBA, JNDI, Servlets, EJB as well as some material on JMS. Check which edition you get as the information dates quickly, though. I was worried when I bought this book that they were attempting to cover too much, but I think they have done a remarkable job. This book really is the most readable introduction to J2EE I have found so far. It's just about small enough to carry about (unlike the massive Wrox tomes), and the API reference can help to keep it useful after you've absorbed the introductory material. It even has a basic SQL reference, which you don't get in some JDBC books!

Summary: A Good Quick Reference
Review: The book "Java Enterprise in a Nutshell" is a dense overview of some of the packages in J2EE. The book has three parts: An introduction, an enterprise reference and an API reference. The introduction describes each package, gives some examples and pointers for further readings. The second part contains reference material on SQL, RMI Tools, IDL and IDL tools and CORBA Services. The API reference lists the complete API of the packages covered by this book. This text is very well written and does an exceptional job in describing the J2EE packages JDBC, RMI, JNDI as well Servelets, EJB and the Java IDL. The chapters are well structured and very clearly written. And they achieve their goal without filling hundreds of pages. Very good. Unfortunately the book does not cover all of today's packages of J2EE but I guess that's the price to pay if the book has to be on the market early enough. The book has some holes, but for the material it covers, it is one of the best, if not the best, books available.

Summary: Compact, concise reference.
Review: This book certainly makes development much easier. Although you can find most of the material in the JavaDocs, the book makes the information much more readily available. Easy to read, easy to reference, concise, accurate. It's certainly earned it's space at the end of my desk.

Summary: Excellent but Incomplete and Dated Reference for J2EE
Review: This book had the misfortune of being written before Java 2 Enterprise Edition (J2EE) was available. As a result, the book doesn't cover some of the packages in J2EE and refers to the packages not in J2SE as "standard extensions". The material the book does cover is still relavent, but will become even more dated with the release of the next version of J2EE. I look forward to the second edition of this book, which I hope would add JSP, XML, and JavaMail to the list of topics, and also cover newer versions of the J2EE APIs. The information given in the book is sketchy in places, and it's in these places that Java Examples in a Nutshell comes in handy. These two books make an excellent pair. But if you're looking for a complete reference to J2EE, this isn't it (yet).

Summary: Just what I needed.
Review: This book is absolutely indespensible for anyone programming Java Servlets, EJB, and CORBA applications. I do all of the above, so this reduces the weight of paper I need to carry around by tenfold. Clear, concise, correct.

Summary: Good, but concise, review of current Enterpirse Java
Review: This book is useful on two fronts: 1) to provide a clear, concise overview of current Enterprise Java technologies, and 2) in the tradition of other Nutshell books, to provide an excellent API reference to the relevant classes. I use it in both senses. If I am presented with an interesting technology that I don't know much about in this area, my first stop is this book to read the concise overview. I would not recommend this book to gain an in depth knowledge in these areas, that chore is better left to more focused books, but once I do master the subject, this book is the first stop for API lookups. The JDBC/SQL references are worth the price of the book themselves. Much better than entire books I have read on the subject.

Summary: O'Reilly scores again
Review: This is a great book... provides short descriptions of the technologies in the Java Enterprise Edition. For each one, covers the architecture, use, and provides examples... everything you need to get started (and for the JavaDoc to make sense). The explanations of the architecture of each technology is especially clear and well written. Also contains the necessary reference material for each technology. This should be next to Java in a Nutshell on the bookshelf of anyone who uses any part of Java Enterprise.
