I have generated java classes from the schema below
using xjc (jaxb version 1.0.3). My test code below
generates an error when I try and marshall the objects
to XML. The error shows that the
SubDExtendsImpl.serializeBody() is being called when I
was expecting it to use
SubDExtends.SubCRestrictsImpl.serializeBody(), which
allows mixed elements where as the former doesn't.
Can anyone else using this schema generate the
following valid XML using jaxb and then marshalling
it:
<Interaction
xmlns:gsd="
http://aurora.regenstrief.org/GenericXMLSchema"
xmlns:hl7="urn::hl7.org"
xmlns:sch="
http://www.ascc.net/xml/schematron"
xmlns:xlink="
http://www.w3.org/TR/WD-xlink"
xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="C:\eclipse
projects\jaxb\jaxb\schema\pds\abstractanonymous.xsd">
<value>Text<subCRestricts>Text</subCRestricts>
</value>
</Interaction>
Is this an error with my code or a bug in jaxb?
Thanks,
Peter Neville
