While agree with Malachi as far as style is concerned (especially w.r.t.
names such as Object), none of these changes make the problem disappear.
Changing the single XML element tag to
<ns:resultPage xmlns:ns="
http://ns.myorg.org/gsearch">
<!-- ... -->
</ns:resultPage>
fixes the problem.
As far as I can understand
http://www.w3.org/TR/REC-xml-names/, the original
XML is correct, and the default namespace is correctly set to {
http://ns.myorg.org/gsearch} for <resultPage> and all elements therein.
I cannot say whether this is a JAXB problem or is due to Apache's SAX parser
not delivering. Feel free to raise an issue at
https://jaxb.dev.java.net/issues/, and attach the xsd and xml.
