hmm... very interesting idea.
And if I'm lucky, there could already be something like that
written(recursively or iterativly runs through an object and puts field
values in a map.)
The only hickup would be to convert basic types to Object representation.
But that shouldn't be too hard. Maybe something already doing that in
beanutils.
I'll look at that,
thx

You could use reflection to populate a map with the fields' values (using
the
field names for keys).
