Java Enterprise Best Practices
by O'Reilly Java AuthorsJava developers typically go through four "stages" in mastering Java. In the first stage, they learn the language itself. In the second stage, they study the APIs. In the third stage, they become proficient in the environment. It is in the fourth stage --"the expert stage"-- where things really get interesting, and Java Enterprise Best Practices is the tangible compendium of experience that developers need to breeze through this fourth and final stage of Enterprise Java mastery. Crammed with tips and tricks, Java Enterprise Best Practices distills years of solid experience from eleven experts in the J2EE environment into a practical, to-the-point guide to J2EE. Java Enterprise Best Practices gives developers the unvarnished, expert-tested advice that the man pages don't provide--what areas of the APIs should be used frequently (and which are better avoided); elegant solutions to problems you face that other developers have already discovered; what things you should always do, what things you should consider doing, and what things you should never do--even if the documentation says it's ok. Until Java Enterprise Best Practices, Java developers in the fourth stage of mastery relied on the advice of a loose-knit community of fellow developers, time-consuming online searches for examples or suggestions for the immediate problem they faced, and tedious trial-and-error. But Java has grown to include a huge number of APIs, classes, and methods. Now it is simply too large for even the most intrepid developer to know it all. The need for a written compendium of J2EE Best Practices has never been greater. Java Enterprise Best Practices focuses on the Java 2 Enterprise Edition (J2EE) APIs. The J2EE APIs include such alphabet soup acronyms as EJB, JDBC, RMI, XML, and JMX.
Java Enterprise in a Nutshell
by David Flanagan William Crawford Jim Farley Kris MagnussonJava Enterprise in a Nutshell is an indispensable quick reference for Java programmers who are writing distributed enterprise applications. The book provides fast-paced tutorials on the following Java Enterprise APIs: JDBC, a vendor-independent API for accessing relational database systems RMI, a Java-only approach to distributed computing that relies on remote method invocation Java IDL, a CORBA-based, language-independent approach to distributed computing Java servlets, a mechanism for extending a web server that allows Java code to perform tasks traditionally handled by CGI scripts JNDI, a generic Java API for working with networked naming and directory services Enterprise JavaBeans, a component model that separates high-level business logic from low-level housekeeping chores like security and transaction management These APIs are the building blocks of the Java 2 Platform, Enterprise Edition (J2EE), Sun's recently announced new platform for enterprise computing. J2EE is the standard Java 2 platform with a number of extensions for enterprise development. Java Enterprise in a Nutshell also contains O'Reilly's classic-style, quick-reference material for all of the classes in the various packages that comprise the Enterprise APIs. This material includes the core Enterprise APIs that are part of Java 1.2, as well as numerous standard extensions. This book is a companion to both Java in a Nutshell, 3rd Edition, which covers the key non-graphical, non-enterprise APIs in Java 1.2, and Java Foundation Classes in a Nutshell, which describes the graphics- and GUI-related classes of Java 1.2.
Java Enterprise in a Nutshell, 2nd Edition
by William Crawford Jim Farley David FlanaganNothing 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.
Java Enterprise in a Nutshell, 3rd Edition
by William Crawford Jim FarleyNothing is as constant as change, and this is as true in enterprise computing as anywhere else. With the recent release of Java 2 Enterprise Edition 1.4, developers are being called on to add even greater, more complex levels of interconnectivity to their applications. To do this, Java developers today need a clear understanding of how to apply the new APIs, use the latest open source Java tools, and learn the capabilities and pitfalls in Java 2 Enterprise Edition 1.4 -- 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 , 3rd Edition. Because most integrated development environments (IDE) today include API lookup, we took out the main API sections from our previous edition to make room for new chapters, among others, on Ant, Cactus, Hibernate, Jakarta Struts, JUnit, security, XDoclet, and XML/JAXP. Revised and updated for the new 1.4 version of Sun Microsystems Java Enterprise Edition software, Java Enterprise in a Nutshell , 3rd Edition is a practical guide for enterprise Java developers.
Java Examples in a Nutshell
by David FlanaganThe author of the best-selling Java in a Nutshell has created an entire book of real-world Java programming examples that you can learn from. If you learn best "by example," this is the book for you. This third edition covers Java 1.4 and contains 193 complete, practical examples: over 21,900 lines of densely commented, professionally written Java code, covering 20 distinct client-side and server-side APIs. It includes new chapters on the Java Sound API and the New I/O API. The chapters on XML and servlets have been rewritten to cover the latest versions of the specifications and to demonstrate best practices for Java 1.4. New and updated examples throughout the book demonstrate many other new Java features and APIs. Java Examples in a Nutshell is a companion volume to Java in a Nutshell, Java Foundation Classes in a Nutshell, and Java Enterprise in a Nutshell. It picks up where those quick references leave off, providing a wealth of examples for both novices and experts. This book doesn't hold your hand; it simply delivers well-commented working examples with succinct explanations to help you learn and explore Java and its APIs. Java Examples in a Nutshell contains examples that demonstrate: Core APIs, including I/O, New I/O, threads, networking, security, serialization, and reflection Desktop APIs, highlighting Swing GUIs, Java 2D graphics, preferences, printing, drag-and-drop, JavaBeans, applets, and sound Enterprise APIs, including JDBC (database access), JAXP (XML parsing and transformation), Servlets 2.4, JSP 2.0 (JavaServer Pages), and RMI The book begins with introductory examples demonstrating structured and object-oriented programming techniques for new Java programmers. A special index at the end of the book makes it easy to look up examples that use a particular Java class or accomplish a desired task. In between, each chapter includes exercises that challenge readers and suggest further avenues for exploration.

Java I/O
by Elliotte Rusty HaroldAll of Java's Input/Output (I/O) facilities are based on streams, which provide simple ways to read and write data of different types. Java provides many different kinds of streams, each with its own application. The universe of streams is divided into four large categories: input streams and output streams, for reading and writing binary data; and readers and writers, for reading and writing textual (character) data. You're almost certainly familiar with the basic kinds of streams--but did you know that there's a CipherInputStream for reading encrypted data? And a ZipOutputStream for automatically compressing data? Do you know how to use buffered streams effectively to make your I/O operations more efficient? Java I/O, 2nd Edition has been updated for Java 5.0 APIs and tells you all you ever need to know about streams--and probably more. A discussion of I/O wouldn't be complete without treatment of character sets and formatting. Java supports the Unicode standard, which provides definitions for the character sets of most written languages. Consequently, Java is the first programming language that lets you do I/O in virtually any language. Java also provides a sophisticated model for formatting textual and numeric data. Java I/O, 2nd Edition shows you how to control number formatting, use characters aside from the standard (but outdated) ASCII character set, and get a head start on writing truly multilingual software. Java I/O, 2nd Edition includes: Coverage of all I/O classes and related classes In-depth coverage of Java's number formatting facilities and its support for international character sets
