Java Application Strategies for the AS/400 [Paperback]

Don Denoncourt (Author)

Book Description

Publication Date: July 1999

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 en! capsulate 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, youll 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, youll discover how to dynamically create hypertext documentation from that code. Included is a companion CD-ROM that contains all the source code presente! d 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).

About the Author

I'm Don Denoncourt, and I'm a Java evangelist. I spent 10 years in the world of business applications design using RPG and COBOL. One day I began to wonder if there was more to programming than structured applications. I bid farewell to friends and family and moved fifteen hundred miles to be a systems programmer at ASNA. There I began a journey of enlightenment as the masters of ASNA taught me the tenants of object-oriented programming with C++. I learned that, although structured techniques had served AS/400 programmers well, there was a better way. After five years, I was ready to come down off the mountaintop and preach the gospel of object-oriented programming. But C++ was a language for computer scientists; not business applications programmers. I needed a language that was not as complex and error-prone as C++ and yet was purely object-oriented. The company called Sun delivered that language to me in the form of Java. The way is object-oriented programming; the language of the way is Java. Midrange Computing has seen fit to give me access to a powerful media to spread my Java evangelism -- as the editor of AS/400 Internet Expert and as a senior technical editor for Midrange Computing. It is my job to help MC readers prepare themselves for a future that involves the bandwidth of the Internet and the language and platform of Java. I thoroughly enjoy it.

4.0 out of 5 stars Highly recommended for RPG programmers., May 13, 2000

This review is from: Java Application Strategies for the AS/400 (Paperback)

It's excellent book for RPG programmers looking for introduction to Java. This book gives solid base in Java with explanations on OO concepts and working practical examples. The only weakness of this book is poor information about how Java works/runs in the AS/400 environment.

This review is from: Java Application Strategies for the AS/400 (Paperback)

As in his seminars, Don Denoncourt attempts to reach two objectives in a very limited time. The first is to teach object-oriented concepts to RPG programmers. He does a pretty good job of this. The second objective, not covered by any other book I am aware of, is to introduce us to the invaluable tools of record-level access and JDBC, as well as PCML and a few other means of interacting with the 400. These sections of the book make it an essential tool for any programmer transitioning AS/400 databases to Java access. I only wish he had included more information on connection strategies such as applets and EJB.
