Subject [jira] [Resolved] (CXF-2779) CXF ignores @XmlAttribute when serializing exception
Date Thu, 01 Sep 2011 16:44:09 GMT


Daniel Kulp resolved CXF-2779.

       Resolution: Invalid
    Fix Version/s: Invalid
         Assignee: Daniel Kulp

I did fix the issue of using getField instead of getDeclaredField.

HOWEVER, the @XmlAttribute thing is not fixed as it would be against the JAX-WS spec and introduce
differences in behavior between CXF and other JAX-WS implementations (including the reference
implementation).   If you want/need information to be in attributes, you must use a fault
bean and use the getFaultInfo way of doing it.

> JAXBEncoderDecoder#unmarshallException} doesn't normally write to private fields, so
exception data isn't propagated, unless:
> * either the {@link @XmlAccessorType} annotation is present on the class and used to
set the default access method to something other than the default XmlAccessType#PUBLIC_MEMBER,
> * or the {@link XmlAttribute} annotation is present on the individual private members
that you want to be serialized.

> @XmlRootElement
> class Bean {
>   @XmlAttribute("sample-field")
>   private String _myField;

> {code}
> Nevertheless:
> * JAXBEncoderDecoder#marshallException calls org.apache.cxf.jaxb.JAXBContextInitializer#isFieldAccepted
to see whether the field should be copied
> * that method fails to check for the XmlAttribute annotation on the field
> * so its value is never serialized or deserialized
> and the attached test case fails unless:
> * either a public getter and setter are provided to turn the field into a property, 
> * or the access type is changed to something other than PUBLIC_MEMBER.
