Overview

This book gives you real-world strategies for the development of AS/400 Java applications. Written specifically for AS/400 RPG programmers, the focus is on business-programming issues for Java application design and programming. Unlike the myriad other books available on Java, this title presumes readers have no C or C++ knowledge or experience. This book describes the structure and the intent of the Java programming language and why Java applications developed with structure techniques used in RPG applications will fail. Also detailed are the benefits and caveats of each of the three Java application architectures: applets, applications, and servlets. You will find out how to recognize the three phases of OOP: encapsulation, inheritance, and polymorphism. And you can learn how to apply standard OO strategies for the development of AS/400 Java applications, create hierarchies of Java classes using OO inheritance in the development of business-object models, and encapsulate business entities that are stored in DB2/400 into Java classes using object-to-relational strategies. You also will be able to create Java GUIs using the Abstract Window Toolkit components of Java 1.1, create robust GUIs using the industrial-strength components of Java 1.2's Java Foundation Classes, and understand the Java GUI replacement strategy for the highly successful AS/400 subfile paradigm. In addition, you can find out how to access DB2/400 data using record-level access, make Java applications interoperate with RPG and COBOL programs, and access DB2/400 data using Java Database Connect (JDBC) and the Java SQL interface. In addition, you'll learn how to properly handle Java errors and create application-specific Java error classes and use the Java language's superior strategy for documenting code. Finally, you'll discover how to dynamically create hypertext documentation from that code. Included is a companion CD-ROM that contains all the source code presented in the book, the complete source for Midrange Computing's Object to Relational framework classes, a .jar file that contains the package of Java classes for Midrange Computing's Object to Relational framework classes, a Sun Java Development Kit, and an Inprise JBuilder 2.0, Trial Version. 400 pages. (Level: Intermediate to Advanced).

Written specifically for the AS/400 RPG programmer, this reference focuses on the business programming issues for Java application design and programming. It assumes no prior C or C++ knowledge or experience. Twenty-one chapters discuss introductory material, strategies for object-oriented design, accessing AS/400, mapping DB2/400 to Java, and grapical user interface. The included CD contains application strategies for the AS/400. Annotation c. Book News, Inc., Portland, OR (booknews.com)
