Java Application Strategies for iSeries and AS/400

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.

Upon completion of this book, you will be able to:
   • Use industry-standard SQL to manipulate and report on your AS/400 data
   • Understand both the structure and the intent of the Java programming language
   • Determine why Java applications developed with RPG structure techniques fail
   • Understand the benefits and caveats of each of the three Java application architectures
   • Recognize the three phases of OOP: encapsulation, inheritance, and polymorphism
   • Apply standard OO strategies for the development of OS/400 Java applications
   • Create hierarchies of Java classes using OO inheritance
   • Encapsulate business entities that are stored in DB2/400 into Java classes
   • Create Java GUIs using the Abstract Window Toolkit (AWT) components of Java 1.1
   • Create robust GUIs with components of Java 1.2's Java Foundation Classes
   • Use the Java GUI replacement strategy for the highly successful subfile paradigm
   • Access DB2/400 data using record-level access
   • Interoperate Java applications with RPG and COBOL programs
   • Access DB2/400 data using Java Database Connectivity (JDBC) and Java SQL interface
   • Properly handle Java errors and create application-specific Java error classes
   • Use the Java language's superior strategy for documenting code
   • Use Java servlets and JSPs to develop powerful server-side Web applications
   • Develop a Model/View/Controller (MVC) strategy
   • Combine JSP, HTML, servlets, Java Beans, and your legacy RPG programs



Don Denoncourt programmed in RPG and COBOL on the AS/400 for eight years before becoming an accomplished object-oriented C++ and Java programmer. He has written dozens of articles on Java and is a staunch evangelist for Java as a language for iSeries and AS/400 business applications.
