Controlling the JAXB context [javax.xml.bind.JAXBException: class
SomeClass nor any of its super class is known to this context.]
Hello,
I am using CXF 2.4.0 + Spring 3.0.5 to create JAX-RS services. In one case
I have a service for which I need to marshal a generic type. When I go
about doing this, I end up getting an exception like this:
[javax.xml.bind.JAXBException: class my.package.ArticleInfo nor any of its
super class is known to this context.]

My data types are:
@XmlRootElement(name = "resultsPage")
public class ResultsPage<T> {
int pageOffset;
int count;
}
@XmlRootElement(name = "resultsPage")
public class ArticlePage extends ResultsPage<ArticleInfo> {
// no extra fields here; just specializes the generic
}
@XmlRootElement(name = "resultsPage")
public class StaffPage extends ResultsPage<StaffInfo> {
// no extra fields here; just specializes the generic
}
How would I instruct CXF to include the classes ArticleInfo/StafInfo/etc
in the JAXBContext used to marshal/unmarshal the data?

Check
http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-SingleJAXBContextandextrauserclasses
mostly identical to the way CXF JAXBDataBinding can be configured
"singleJAXBContext" is an optional property - it can be used to have a
context created once at the start up, but setting it is not needed for
the extra classes be taken into account.
Using @XmlSeeAlso, or "marshalAsJaxbElement" property are other options

Sorry about this question; just realized it's purely JAXB-related.
I've gotten around it by using @XmlSeeAlso as follows:
@XmlRootElement(name = "resultsPage")
@XmlSeeAlso({ ArticleInfo.class })
public class ArticlePage extends ResultsPage<ArticleInfo> {
}
