commons-validator : HaspMap/Collection instead of JavaBean

[Yuvraj Waswani <Yu...@tavant.com>]

Hi,
 
Can we use Hashmap or any other Collection instead of a JavaBean with
Validator? If not, what alternatives do I have to be able to convert a
HashMap/Collection to a JavaBean WITHOUT any pre-existing Bean definition?
(The Collection/HashMap I get from the application is dynamic in nature and
so cannot have a predefined JavaBean class for it). 
 
I take this mail as an opportunity to ask another question :-- Can I
construct a JavaBean (since it has to be used with Validator) from an XML
containing its definition (like javabean property names) , again WITHOUT any
pre-existing class definition?
 
Awaiting some response.
 
Thanks.
