I had a look into the [beanutils] code, and indeed it does not seem to
be possible to register a converter for a base class and classes derived
from it. When looking up a converter for a given class always an exact
match is needed (actually it is a get operation on a hash map).
So there is no easy and official solution to this problem. You might
want to open an enhancement request in our bug tracking system [1], but
I cannot promise that this feature will be made available soon.
As a work-around: Would it be possible to do the registration with a
concrete XMLGregorianCalendar object at hand? If you had such an object,
you could do something like
ConvertUtils.register(new XMLGregorianCalendarConverter(),
myCalendarObj.getClass());
