Allow for unmarshalling of non-@XmlRoot types [SWS-580]

[gregturn]

David J. M. Karlsen opened SWS-580 and commented

When unmarshalling non-@XmlRoot element types there is a need to specify the expected type,
and I have to use a workaround to work with the native jaxb2 unmarshaller, like this:

JAXBElement<S2SDDDirectDebitTransactionInformation2> element = ebaUnmarshaller.getJaxbContext().createUnmarshaller().unmarshal( source, S2SDDDirectDebitTransactionInformation2.class );

It would be handy to expose a method to give the expected return type - and this should be a generic/parameterized method.
See: http://www.docjar.com/docs/api/javax/xml/bind/Unmarshaller.html "Unmarshal a root element that is globally declared" and the following section for an thorough explaination.

Problem is that not all OXM frameworks support this functionality.

David, how did you access JAXBContext when that getter is protected in Jaxb2Marshaller?

Maybe just exposing that getter as public would suffice.

This issue should be moved to Spring Framework JIRA, since OXM module is now part of Spring Framework itself.

It's not a protected method, nor is it specific to any framework.
It's declared in the API interface:
http://docs.oracle.com/javaee/5/api/javax/xml/bind/Unmarshaller.html
It's now resolved in the framework: https://jira.springsource.org/browse/SPR-10282 to be released in 3.2.2.

David, in your example from this issue description, you use getJaxbContext() method of Spring's Jaxb2Marshaller which is protected.
(see here).

Thanks for reference to SPR-10282. Then this one can be closed.
