If you are a good Java programmer who wants to become an excellent Java application developer, this book and companion CD-ROM are for you. This book contains 64 chapters written by 18 leading Java experts on Java technologies. Originally compiled by Don Denoncourt as a personal resource to help him develop and code Java applications for his consulting business, iSeries and AS/400 JavaTM at Work contains all the essential information Denoncourt has gleaned from his years as the editor of AS/400 NetJava Expert, a on time contributor to Midrange Computing, and an award-winning seminar speaker. I consider this book to be my secondary storage device for Java technology, says Denoncourt. It is an extension of my Java capabilities, and it could be the same for you. This is not a book for the beginner Java programmer. Rather, it is the definitive second-tier education for Java programmers. Many know the language; those who succeed will know how to make the language work in a business environment. This book will show you how the experts are getting it done. Java is a pervasive technology today. iSeries and AS/400 shops are clamoring for Java expertise so that they can modernize their business applications and build their Web presence. Businesses need Java programmers who can use their skills to contribute real value as application developers. Successful Java programmers need more than basic Java programming skills; they need a strong grasp of business--real-world tools to develop robust applications. There has never been a better time to build your Java skills, and there has never been a better resource to help you do it than iSeries and AS/400 Java at Work

The Application System/400 (AS/400) is IBM's family of full-range, general purpose computers, which encompass a broad range of related models. This book is a complete guide to the AS/400 system, utilities, database structure, and programming.

Not just another Java tutorial, this detailed guide takes you through everything you need to know about the AS/400's implementation of Java Book jacket.

Java Application Strategies for iSeries and AS/400--Second Edition provides a much-needed look at the realities of using Java to develop real-world OS/400 applications. Don Denoncourt draws on his years of experience as a business application programmer and on his acknowledged expertise in Java to lead RPG programming professionals through the potential pitfalls of object-oriented programming (OOP), teaching them effective strategies for Java application design and programming. Covering the gamut of Java application strategies, this book includes introductory information on Java and object-oriented programming, methods for integrating object-oriented techniques into your application design, a description of the utilities and tools available on iSeries and AS/400, methods to access DB2/400 with Java, ways to integrate Java with your legacy applications, and a tutorial on how to develop a Java GUI. New to this edition are sections on server-side Java and the Web--an up-to-date look at servlets, JavaServer Pages (JSPs), and programming server-side applications on the Web.

& • Everything Java developers need to start building J2EE applications using WebSphere Tools for the WebSphere Application Server & & • Hands-on techniques and case studies: servlets, JSP, EJB, IBM VisualAge for Java, and more & & • Written by IBM insiders for IBM Press

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform. This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them. The topics covered include · Dividing an enterprise application into layers · The major approaches to organizing business logic · An in-depth treatment of mapping between objects and relational databases · Using Model-View-Controller to organize a Web presentation · Handling concurrency for data that spans multiple transactions · Designing distributed object interfaces
