Hello , I downloaded the the sample **[lyo-adaptor-sample-modelling](https://github.com/OSLC/lyo-adaptor-sample-modelling)** and ran the adaptor-rm-webapp correctly. All urls are working fine except the url : [http://localhost:8083/adaptor-rm/services/requirements/create](http://localhost:8083/adaptor-rm/services/requirements/create) . I can’t create a requirement using the creation factory . I have this bug : ![Capture d’écran 2022-11-05 à 22.53.41](https://forum.open-services.net/uploads/default/original/1X/0c1e712964ae200bffa84054b80e1b242e0a7a3c.png) I even created my own application using lyon designer and it’s the same for the creation factory part, I still have the same bug : 404 not found . Any idea ? Thank you so much ---

Hi @onsDridi Most likely you are doing a GET on that creationFactory (I am guessing since I see input from a browser). For a creation you need to do a POST. and for that , you need to use applications like Postman. Plus, you need to send the resource you are creating in the body. Otherwise, can I suggest you use the OSLC Reference Implementation ([GitHub - oslc-op/refimpl](https://github.com/oslc-op/refimpl)) instead of the sample adaptors? The sample adaptors are just to simple, and have not been updated for a while. In the refernce implementation, you can also see how a client is used to call the creation factory. ---

Hello jad, Thank you for your response . When I use postman to create my ressource , I get this error : ![Capture d’écran 2022-11-07 à 09.43.50](https://forum.open-services.net/uploads/default/original/1X/9cfd1651a4eb2de9d940c520c12d88d28128e196.png) ---

It’s the same problem with the refimpl sample . For the OSLC server-rm , I used postman to create a requirement : ![Capture d’écran 2022-11-07 à 16.18.07](https://forum.open-services.net/uploads/default/original/1X/3c4a0a0bd63c8c78f2a05a9a0fa9cf30606b09b9.png) and I got the same error ! ---

Hi The resource you are sending does not seem to be valid. It lookes like basic json, but you need to send rdf. Tips is to do a GET on a resource that exists. And, then copy the response as the body for your POST request.
