(1) You have to specify the namespace for the root element:
@XmlRootElement(name="content-types",
namespace="
http://xmlns.escenic.com/2008/content-type")
(2) Never, ever add a namespace prefix to an element name in the
"name" part of an annotation. (The "ui" is absolutely local to the XML
file, and could be systematically replaced by anything.)
(3) Make sure to use exactly identical URIs (no trailing '/' here):
@XmlElement(name = "label",
namespace="
http://xmlns.escenic.com/2008/interface-hints")
protected String label;
