I don't understand. 
So either you don't undetrstand or you haven't explained it very well. ;-)

You can't set a property unless it exists in the BeanInfo


  | public class MyClass
  | {
  |    private Date myDate;
  | }
  | 

This should have a BeanInfo with one property which is a FieldPropertyInfo
i.e. instead of:
MethodInfo getter, setter;
it has
FieldInfo field; (there is no getter/setter)

propertyInfo.getType() -> field.getType(); // instead of the "return type"
propertyInfo.set() -> field.set(); // instead of a method invocation
