There is no way to really handle this via Jackson API. But you might be able to achieve this by constructing `XMLStreamWriter` explicitly, and then pass it as target via `XmlMapper`. This does allow pre-registering of namespace/prefix bindings... although that alone does not (and can not) force writing of namespace for root element unless it is needed for root element itself. You could force writing of root element itself, and if so also force writing of namespace declaration (even in repairing mode). But I don't know if it's then possible to make Jackson serialize just contents of root element (things might work if root only has one child element). -+ Tatu +- -- You received this message because you are subscribed to the Google Groups "jackson-user" group.
