I have a CLM 6.0 installed on WAS 8.5.5. I am trying to connect to the Requirements Management (RRC) using OSLC version 2.0. The code is failing at the getServiceProvider function. The exception that I am getting is-
[Fatal Error] :17:78: The reference to entity "etag" must end with the ';' delimiter.
org.xml.sax.SAXParseException: The reference to entity "etag" must end with the ';' delimiter.

The getServiceProvider method has the following code-

public String getServiceProvider(String catalogURI, String paName) throws InvalidCredentialsException, IOException, XPathExpressionException {
        HttpGet query = new HttpGet(catalogURI);
        query.addHeader("Accept", "application/rdf+xml");
        query.addHeader("OSLC-Core-Version", "2.0");
       
        // Access to the Service Providers catalog
        HttpResponse response = HttpUtils.sendGetForSecureDocument(
                                                server, query, login, password, httpclient, JTS_Server);
        if (response.getStatusLine().getStatusCode() != 200) {
            response.getEntity().consumeContent();
            throw new HttpResponseException(response.getStatusLine().getStatusCode(), response.getStatusLine().getReasonPhrase());
        }
       
//        System.out.println(" !!! Service Providers catalog");
//        printEntity(response.getEntity());
        // Define the XPath evaluation environment
        XPath xpath = getXpathNamespace();
        String serviceProviderXPath = "//oslc:ServiceProvider[dc:title=\""+paName+"\"]/@rdf:about";

        // Retrieve the designated Service Provider
        InputSource source = new InputSource(response.getEntity().getContent());
        Document doc = parse(source);
        Node paNode = (Node)(xpath.evaluate(serviceProviderXPath, doc, XPathConstants.NODE));
        if (paNode == null) {
            if (DEBUG)
                System.out.println("!!! using alternative service provider file format");
            serviceProviderXPath = "//oslc_disc:ServiceProvider[dc:title=\""+paName+"\"]/oslc_disc:services/@rdf:resource";

            // Retrieve the designated Service Provider
            paNode = (Node)(xpath.evaluate(serviceProviderXPath, doc, XPathConstants.NODE));
        }
        if (paNode == null) {
            response.getEntity().consumeContent();
            throw new RuntimeException("Unknown Project Area: "+paName);
        }
        response.getEntity().consumeContent();
        return paNode.getTextContent();
    }

The service provider is coming as null. Do I need to make any change in the service provider code to make it work for CLM 6.0?
