Description:

Most Java developers are used to creating Java classes that conform to the
JavaBeans naming patterns for property getters and setters.
It is natural to then access these methods directly, using calls to the
corresponding getXxx and setXxx methods. However, there are some occasions
where dynamic access to Java object properties (without compiled-in knowledge
of the property getter and setter methods to be called) is needed.

Example use cases include:
- Building scripting languages that interact with the Java object model (such
as the Bean Scripting Framework).
- Building template language processors for web presentation and similar uses
(such as JSP or Velocity).
- Building custom tag libraries for JSP and XSP environments (such as Jakarta
Taglibs, Struts, Cocoon).
- Consuming XML-based configuration resources (such as Ant build scripts, web
application deployment descriptors, Tomcat's server.xml file).

The Java language provides Reflection and Introspection APIs (see the
java.lang.reflect and java.beans packages in the JDK Javadocs).
However, these APIs can be quite complex to understand and utilize.
The BeanUtils component provides easy-to-use wrappers around these
capabilities.
