Exception Summary

BeansException	Abstract superclass for all exceptions thrown in the beans package and subpackages.

Package com.interface21.beans Description

This package contains interfaces and classes for manipulating Java beans. It is used by most other Spring packages.

A BeanWrapper object may be used to set and get bean properties, singly or in bulk.

The classes in this package are discussed in Chapter 11 of Expert One-On-One J2EE Design and Development by Rod Johnson (Wrox, 2002).
