Hi Andrew,
Unmarshaller.setValidating is indeed deprecated and you need to set the
Schema object to validate against.
In this respect i am unsure how you can create a general validating
mechanism unless you keep a map of known JAXB class to Schema instance.
You will have to create the Schema instances from the correspondingly
available XSD, more info can be found here [1].
Rather than creating a general validating mechanism it might be better
to have a general mechanism you inherit from for specific validating
purposes i.e. provides the JAXB context and a set of schema.
Paul.
