There are some pretty significant challenges in getting this to work -- in
particular, a PropertyDescriptor wants to include a Method for the
property getter and setter methods, but the signatures won't match the
JavaBeans design patterns.
An alternative way to introspect a DynaBean is like this:
DynaBean myDynaBean = ...;
DynaClass myDynaClass = myDynaBean.getDynaClass();
DynaProperty myDynaProps[] = myDynaClass.getDynaProperties();
Each dynamic property has a small descriptor that includes the name and
type of the underlying property. This will work on any correctly
coded DynaBean implementation (including, for example, DynaActionForm).
