Method declaration is like (not working in CXF v2.4.0... but worked fine in
v2.2.3):
@POST
@Path("mypath")
@Consumes({"application/json", "application/xml"})
public JAXBElement<MyElement> methodName(JAXBElement<? extends ParentClass>
zzz)
Workaround is to declare method like:
@POST
@Path("mypath")
@Consumes({"application/json", "application/xml"})
public JAXBElement<MyElement> methodName(ParentClass zzz)
