org.apache.olingo.odata2.api.processor.ODataResponse
An ODataResponse is usually created by an {@link ODataProcessor} during request handling.
The handler can use a serializer to create an OData body (== response entity) and can set various response headers. A response can be created using the builder pattern:
```
  {@code ODataResponse response = ODataResponse.entity("hello world").setStatus(HttpStatusCodes.OK).build();} 
```

  }


  private void createMethodNotAllowedResponse(final HttpServletRequest req, final MessageReference messageReference,
      final HttpServletResponse resp) throws IOException {
    ODataExceptionWrapper exceptionWrapper = new ODataExceptionWrapper(req);
    ODataResponse response =
        exceptionWrapper.wrapInExceptionResponse(new ODataMethodNotAllowedException(messageReference));
    createResponse(resp, response);
  }
