Alex Franken commented on CXF-1858:
-----------------------------------
I have also updated to 2.1.3. The following ExceptionMapper throws an
exception. I have also included the skeleton of the service class. My use
case is sending a "PUT" request to the expandPatient service.
@Provider
public class FaultExceptionMapper implements ExceptionMapper<Fault> {
protected final Log log = LogFactory.getLog(getClass());
@Override
public Response toResponse(Fault fault) {
log.debug("Fault
thrown:"+fault.getCode()+":"+fault.getMessage());
log.error(fault.getMessage(),fault);
/* works
* return Response.status(Response.Status.NOT_FOUND).build();
*/
return Response.status(Response.Status.NOT_FOUND)
.type("text/plain;charset=utf-8")
.entity("THIS IS A TEST ENTITY-BODY").build();
}
}
@Path("/PatientService")
@ProduceMime("application/xml")
public class RESTfulPatientServiceImpl extends AbstractRESTfulService
implements PatientService {
....
@GET
@Path("/expandPatient/{institutionID}/{medicalRecordNumber}")
public DOMSource expandPatient(@PathParam("institutionID")String
institutionID, @PathParam("medicalRecordNumber")String medicalRecordNumber){
}
}
