The practical, succinct focus here on actual Java enterprise APIs helps distinguish this text from the pack. Early sections provide short, clear examples along with just enough background to help you use APIs like JDBC, servlets and JSPs, EJBs and others. Coverage of Java's ability to interface with legacy CORBA systems is just excellent here, with a full tour of Java IDL, CORBA services and Remote Method Invocation (RMI). Typically, readers will be familiar with some J2EE APIs and not others. This book can help fill in the gaps.

Updated with the latest standards from Sun including JDBC 3.0, Servlet 2.3 and EJB 2.0, this is an essential primer of today's high-end (and high-paying) Java. The basic presentation of servlets/JSP and EJBs (among the most important APIs for current Java Web development) are concise and nicely digestible. We also liked the chapter on JMS for messaging (also a hotbed of Java job activity).

The second half of this text lists every J2EE class along with methods and properties in a very valuable reference making good use of two-toned shading for easy access. Entries are organised by package name. (One small oversight here is that an index of cross-listed packages, classes and methods omits page numbers.)

Overall, this reference material will serve as truly indispensable for any working Java programmer. The second edition of Java Enterprise in a Nutshell is a fully up-to-date tutorial and reference that lives up to the standards of O'Reilly's Nutshell series. Both thorough and concise, it's a handy resource for anyone who works with the hundreds and thousands of Java enterprise APIs on a regular basis. --Richard Dragan

Book Description
Nothing is as constant as change, and this is as true in enterprise computing as anywhere else. Since Java Enterprise in a Nutshell was first published in September of 1999, a dozen or more new APIs have been added to the platform, reflecting the new and different ways developers implement their enterprise objectives. And now developers are being called on to add even greater, more complex levels of interconnectivity to their applications, as the concepts behind Web Services solidify and implementation decisions need coding.

Java developers today need a clear understanding of the new APIs, tools, capabilities and pitfalls in J2EE 2.0 so they can plan a technology and implementation strategy for new enterprise projects. Fortunately, this is exactly what they get with the new Java Enterprise in a Nutshell, 2nd edition!

Completely revised and updated for the new 2.0 version of Sun Microsystems Java Enterprise Edition software, Java Enterprise in a Nutshell 2nd edition covers all of the J2EE APIs, including RMI, Java IDL, JDBC, JNDI, Java Servlet, and Enterprise JavaBeans, with a fast-paced tutorial and compact reference on each technology. Then Java Enterprise in a Nutshell goes even further, providing a classic O'Reilly-style quick reference for all of the classes in the various packages that comprise the Enterprise APIs - covering the core enterprise APIs as well as numerous standard extensions.
