JAXB custom namespace prefix issue

Is there any other way to control the custom namespace prefixes using annotations other than in the package level annotation @Xmlns.

Can it be done at the element level? Also is it possible to have one namespace with multiple prefixes?

What do you want to do, actually? Why are namespace prefixes important for you?

There are no standard element-level annotations for namespace prefixes.

The options to control namespace prefixes I know are:

  • @XmlNS you already mentioned.
  • Providing a custom NamespacePrefixMapper.
  • Lower-level handling of XML (for instance, on the StAX, SAX or DOM level).

What I also can imagine:

  • @XmlElementRef/@XmlElementRefs normally use JAXBElements which have QNames which have prefixes. Maybe this prefix will be used.
  • You can have a QName-typed property (xs:QName in XSD), it also may be used to add a namespace mapping.
  • Probably something in direction of @XmlAnyElement (containing DOM element).
  • I think I also saw something in direction of XmlAdapter - I think there was an option somewhere for it to be NamespacePrefixMapper-aware. (Actually needed for namespace-aware types like QName).
