Ok, I am feeling really dumb here :( But I can't figure out how this
works the other way. i.e. Marshalling a sub-element.
When I do:
marshaller.marshal(instanceOfBoundBean2.getSomeElement(), aStringWriter);
I get
==========
Caused by: com.sun.istack.SAXException2: unable to marshal type
"com.ual.hcp.poc.schemas.generated.jaxb.ApolloOpenSessionRQ$Request"
as an element because it is missing an @XmlRootElement annotation
at com.sun.xml.bind.v2.runtime.XMLSerializer.reportError(XMLSerializer.java:244)
at com.sun.xml.bind.v2.runtime.ClassBeanInfoImpl.serializeRoot(ClassBeanInfoImpl.java:303)
at com.sun.xml.bind.v2.runtime.XMLSerializer.childAsRoot(XMLSerializer.java:490)
at com.sun.xml.bind.v2.runtime.MarshallerImpl.write(MarshallerImpl.java:328)
... 33 more
===========
I read the Javadoc of the Marshaller where it says the object being
passed in either has to be annotated as @XmlRootElement, or has to a
be "wrapped" to an JAXBElement. And I have no idea of either:
1. The Java class is generated by xjc, am I supposed to annotate it
with @XmlRootElement by hand?
2. I don't understand how come "instanceOfBoundBean2.getSomeElement()"
is NOT of type "JAXBElement". And if it is really not, how do I "wrap"
it into one?
Thanks again!
