Description

I've tried building a client for an endpoint whose interface is as follows:

@WebService(targetNamespace = "http://www.jboss.org/wise/adapter/", name = "Endpoint")
@XmlSeeAlso({ObjectFactory.class})
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface Endpoint {

    @WebResult(name = "mimepart", targetNamespace = "http://www.jboss.org/wise/adapter/", partName = "mimepart")
    @XmlJavaTypeAdapter(value = HexBinaryAdapter.class)
    @WebMethod
    public byte[] getData(
        @WebParam(partName = "dataQuery", mode = WebParam.Mode.INOUT, name = "dataQuery")
        javax.xml.ws.Holder<DataQuery> dataQuery
    );
}

and I'm getting the following exception:

The problem seems to be basically due to JAXBDataBase#getJAXBAnnotation(MessagePartInfo mpi) searching return annotations even for input messages.
