Resource.save does not use java.io.Serializable, so is unaffected by
whether the data type supports that. Of course there could be some
detail you're leaving out, but normally an XMLResourceImpl is used and
what's saved is an XML representation. That XML can be sent anywhere
else and read back in. There really must be some detail you're leaving
out...

With the 2.5.0 runtime, our XMLDuration implementation class does
support java.io.Serializable directly...
