Description

I'm attempting to return a @XmlRootElement annotated object called "Customer" from a @WebMethod. When calling the service, I get the following error in the server log:

javax.xml.bind.JAXBException: [Lcom.gmail.at.cedrichurst.complexDataTypeWSExampleEJB.domain.Customer; is not known to this context

From what I understand, the return type should be added to the JaxB context automatically.

Just to make sure I wasn't doing something wrong in my Customer class, I added another method to my bean that returned a java.util.List of Strings. When calling this method, I also got the same sort of error:

[javax.xml.bind.JAXBException: java.util.List is not known to this context]
javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException

According to a thread in the OpenEJB mailing list:

http://www.nabble.com/Returning-complex-data-types-in-%40WebResult-tc15114306.html

...it doesn't seem that these errors should be happening.

I attempted to test this under CXF, but ran into another issue which is outlined in another JIRA.

EAR file and geronimo.log attached.
