The Bean Introspection Utilities component of the Jakarta Commons subproject offers low-level utility classes that assist in getting and setting property values on Java classes that follow the naming design patterns outlined in the JavaBeans Specification, as well as mechanisms for dynamically defining and accessing bean properties.

The Bean-Collections optional distribution contains objects which apply these techniques to collections. They rely on commons-collections 3.0 (or higher).

The documentation for this optional package is included with the core Beanutils documentation.
