OSLC explanations for HTTP codes
OSLC uses standard HTTP response codes as error messages. For example, the HTTP 404 response is normally returned when a web page is not found, and in OSLC the 404 response code is returned when the resource cannot be found.
Some existing error codes are mapped to HTTP codes by default,
but you can map additional codes as required.
The following HTTP response codes are implemented by OSLC :
- 200
- Success
- 201
- Success. The response contains a link.
- 204
- Resource successfully updated. There is no response entity.
- 400
- Error handling request. This error might be due to the request content or URI. For example, there might be a business logic validation error on the server side.
- 401
- Authentication failure.
- 403
- Forbidden. The user password expired.
- 404
- Resource cannot be found or an invalid resource type was provided.
- 405
- HTTP method cannot be used for the resource.
- 406
- Requested representation is not supported.
- 410
- Stable resource page expired.
- 412
- Resource on the client side is stale and must be refreshed from the server. The conditional update failed because the resource was updated by another user or process.
- 500
- All other server errors.
The messages support the languages that are supported by IBM® Maximo® Real Estate and Facilities.
