I am trying to get work items and their linked test cases in order to store that data in a database. I can access work items thanks to JAVA API and I list the linked test cases as urls:

For instance in the Project Area "ZZZ" there is one work item named "YYY" that has the following test case:

https://localhost:9443/qm/oslc_qm/contexts/_ueOOYKgQEeaPaoGRbbL1BA/resources/com.ibm.rqm.planning.VersionedTestCase/_LsP4sKqLEeaPaoGRbbL1BA

Now I want to retrieve information of this test case. I was pointed in another question that I should use OSCL request since RQM doesn't have a JAVA API like RTC does. So I am digging into OSCL options and I have also download the OSCL-Workshop and their examples. I can connect to the server and authentificate to my https://localhost:9443/qm server but how could I retrieve the test case info based on the aforementioned test case url?

This is the login test based on the OSCL-Workshop example:

public static void main(String[] args) {
        //============== Code to adapt to your own configuration =============//
        String server = "https://localhost:9443/qm";        // Set the Public URI of your RTC server
        String login = "login";                                    // Set the user login
        String password = "password";                                // Set the associated password
       
        System.out.println(">> Example02: Print out the content of the Service Providers catalog");
        System.out.println("    - Login: "+login);
        System.out.println("    - Password: "+password);

        JazzFormAuthClient client = null;
        try {
            //Initialize a Jazz rootservices helper and indicate we're looking for the ChangeManagement catalog
            //RTC contains a service provider for CM and SCM, so we need to indicate our interest in CM
            JazzRootServicesHelper helper = new JazzRootServicesHelper(server, OSLCConstants.OSLC_QM_V2);
           
            //Create a new Form Auth client with the supplied user/password
            client = helper.initFormClient(login, password);
           
            //Try to login
            if (client.formLogin() != HttpStatus.SC_OK) {
                System.out.print(">> login failed.");
                return;
            }
           
            //Fetch the catalog of service providers.
            ClientResponse response = client.getResource(helper.getCatalogUrl(), OSLCConstants.CT_RDF);
            ServiceProviderCatalog catalog = response.getEntity(ServiceProviderCatalog.class);
           
            if (catalog != null) {
                for (ServiceProvider sp : catalog.getServiceProviders()) {
                    System.out.println(">> \t - "+ sp.getTitle());
                }
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (RootServicesException e) {
            e.printStackTrace();
        } catch (OAuthException e) {
            e.printStackTrace();
        } catch (URISyntaxException e) {
            e.printStackTrace();
        } catch (JazzAuthFailedException e) {
            e.printStackTrace();
        } catch (JazzAuthErrorException e) {
            e.printStackTrace();
        } finally {
            // Shutdown the HTTP connection
            if (client != null) {
                client.getHttpClient().getConnectionManager().shutdown();
            }
        }
    }
