Query: Confusing book about beans

This is not a good tutorial about Java Beans. In order to explain the Java Bean concept you have to start with the Java Beans specifications of Sun. This would answer question about which things are relevant and why they are relevant in JavaBeans development. Now the the reader almost jumps into a long winded explanation about events and adapters, wondering why this is relevant and what the writer wants to explain. To make matters worse: the example contains errors! Basically, after the first three chapters I was utterly confused.This book also needs a clearer description about the use of Java Beans. In a next update we definitely need a chapter about how JavaBeans are used in Java Server Pages.
