Does NOT teach Java, and goes through VisualAge too rapidly. 2 out of 5 stars.

This book is definitely NOT for the RPG programmer wishing to learn about Java. I have marked this book down heavily for its misleading title: implying that it explains Java as well as Visual Age for Java (VAJ). The book assumes not just a basic, but a *thorough* knowledge of the Java language, on which it builds its VAJ examples.The VAJ examples leave something to be desired, since they are presented as completed, with the text and diagrams then referring to specific parts of an example and showing the Java code generated (meaningless to me).
The book works through a series of advanced topics extremely rapidly. I realised how rapidly, when reading topics with which I am familiar (e.g. IFS). For a reader with existing knowledge, I think the book would work well - but for a "new to Java" reader, it's too brief.
What the book does not do, is take someone completely new to the VAJ environment, step by step through building the examples.
In conclusion, the book is a very good reference for the moderately experienced Java and VAJ developer, who wants to check on how to do something in the AS/400 environment. But it is of little use to someone such as myself, an experience RPGIV developer with no Java or VAJ experience.
I am now left with the dilema of using Amazon's no quibble returns guarantee; or buying yet another book on AS/400 Java, and some basic VAJ training, before trying this book again.
Editorial Review:
This is a practical introduction to software development in Java on the AS/400. The first section takes the reader through a simple Java example in order to demonstrate an overview of the AS/400's Java functionality. The second section gives implementation specifics. The final section guides the reader through several complex application examples, which reveal how developers can exploit Java's full potential on the AS/400.
