How do I specify a pattern constraint using JAXB annotations?

Question

I'm developing a SOAP application using JAX-WS and JAXB. I'd like to specify a pattern constraint for one of the fields (a Dutch postcode, \d{4}[A-Z]{2}). That's very easy to do using xsd:pattern, but I can't find the equivalent JAXB annotation. How do I achieve this?

Answer 1

You can't. The idea is to use JAXB annotations in combination with runtime validation against the schema, using javax.xml.validation.Schema, which can be plugged into the Marshaller and Unmarshaller.
