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

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.

Doug Pence and Ron Hawkins have spent the last two decades accumulating tips, tools, and techniques that make RPG the best that it can be. From designing software to attaining maximum performance to using advanced problem-solving tools, this book presents a wide range of important topics. It offers in-depth, practical coverage of basic subjects--such as data structures, string handling, and subfiles--and also tackles the more intricate subject areas, such as APIs, prototyping, and journaling as a debugging tool. It covers built-in functions (BIFs), data types, and subprocedures. From coding to compiling, this book has tips for RPG programmers of every level.

Database access is the heart of iSeries web applications. There are two main techniques available: JDBC and Record Level Access (RLA). RLA is similar to using file I/O operations in RPG, while JDBC uses SQL. Which should you use for any given job? Whether you're creating web applications, client programs, or server-side code, you need to know how to effectively use JDBC or RLA to access your iSeries data. In this new, fast-paced 20-hour training course, Joe Pluta takes you step-by-step through many labs which allow you to compare and contrast both JDBC and RLA. Using these short, easy to understand labs, you'll create Java classes to read files sequentially and by key. You'll learn how to create complete CRUD classes (Create, Read, Update, Delete) using both RLA and JDBC. TOPICS COVERED IN THIS HANDS-ON COURSE INCLUDE: ?Sequential access with RLA and JDBC ?Creating and closing connections ?Working with records and fields from database files ?Using RLA and JDBC for keyed access ?Updating records using RLA and JDBC ?Error handling using the database access techniques ?Inserting new records with RLA and JDBC ?Creating a 3-tier client application to display, insert, update and delete data ?Using an Abstract Class to simplify Java development ?The JBUI classes to provide powerful user interfaces, far simpler than AWT or Swing NOTE: This course uses VisualAge for Java version 3.5 or 4.0, provided with the IBM WebSphere Development Tools for iSeries. Some experience with Java is assumed. When should you use JDBC? When should you use RLA? With this training you?ll always make the right choice to maximize Java Database performance and make your job easier.

This IBM® Redbooks® publication explains how to configure and manage independent disk pool (IASP) functionality of IBM i 6.1. It is designed to help IBM technical professionals, business partners, and customers understand and implement independent disk pools in the IBM i 6.1. In addition, this publication provides the background information that is necessary to plan, implement, and customize this functionality to your particular environment. It provides guidance on running user applications with either application data or most application objects residing in an independent disk pool. Considering that you can also use independent disk pools in a cluster environment, this publication shows you the basic steps to make your independent disk pool switchable between two Power SystemsTM servers or a single server with multiple LPARs. Independent auxiliary storage pools have many business and technical advantages for Power Systems using IBM i. Not only are independent auxiliary storage pools (IASPs) easy to create and maintain, most applications can use them by simple work management changes. IASPs can provide immediate benefits to your enterprise.

IBM® delivered IBM i 6.1 in March 2008. With 6.1, IBM exploits the capabilities of the Machine Interface (MI) architecture to significantly improve programs. Programs can benefit from better performance, a range of new operating system and processor capabilities, and even stronger system integrity. To enable these improvements, all MI programs created for previous releases must be converted to run on 6.1 or a later release. MI programs include integrated language environment (ILE) and original program model (OPM) programs. To convert a program, its creation data, which is a subset of observability, must be available. MI programs retain creation data by default, so that most programs can be converted, going all the way back to programs that were originally created for System/38. Even if an option was chosen to remove creation data from external access, Licensed Internal Code (LIC) can still access the creation data if the target releases of the program and its constituent modules are V5R1 or later. Thus a program lacks sufficient creation data for conversion only if the program or at least one of its modules was created for IBM OS/400® V4R5 or an earlier release and creation data was explicitly removed. You can run the Analyze Object Conversion (ANZOBJCVN) command on V5R4 or V5R3 to help plan for your upgrade. The ANZOBJCVN command identifies programs that will not convert to run on 6.1 or later releases, if any, and estimates the times that are required for the program conversions. It also provides information about two other types of conversions: integrated file system names and spooled files. You can access the ANZOBJCVN command by loading and applying the appropriate PTFs that are listed in this paper. This IBM RedpaperTM publication is intended for system administrators and field technicians to help them understand and prepare for upgrading or migrating to 6.1 or a later release. It explains what the program conversion is and why programs are being created or recreated on 6.1 or a later release. It then provides detailed steps for using the ANZOBJCVN tool on V5R3 or V5R4 to prepare for object conversions. Finally, it discusses the program conversion methods for converting programs to run on 6.1 or a later release. Note: The first edition of this paper was entitled IBM i5/OS Program Conversion: Getting Ready for i5/OS V6R1, REDP-4293-00. The title of this second edition has been slightly modified to IBM i Program Conversion: Getting Ready for 6.1 and Beyond, REDP-4293-01, to reflect the new naming conventions for IBM i.
