Hello.
I need to create a java client that can talk with RTC (4.0.1) via OSLC, to create/read/update WI.
I started with installing the OSLC4J 1.1. project (eclipse lyo),and running the RTCFormSample provided with it.

WIs query and update work fine, but the "create" of a ChangeRequest (WI) fails.
To be more exact, it simply doesn't work, since it does not throw any exception/error.

The code in the sample is:

//Create the change request
ClientResponse creationResponse = client.createResource(
                           changeRequestCreation, changeRequest,
                           OslcMediaType.APPLICATION_RDF_XML,
                           OslcMediaType.APPLICATION_RDF_XML);

String changeRequestLocation = creationResponse.getHeaders().getFirst(HttpHeaders.LOCATION);

You can realize that "create" fails since the "changeRequestLocation" is null.

I have debugged a little bit the code, and I found that the ClientResponse fields "status" and "message" are respectively "403" and "forbidden".

Since I'm quite sure that credentials are correct, and they are allowed to create a WI (I've verified from RTC WUI), have you any idea what could be the problem?

Could it be the version of the OSLC libraries?

thanks in advance
