Getting Object Information

I'm executing the following code from our samples in Java:

 

    public static void head(HttpClient client, String auth) throws IOException{

        //specify namespace URL - eg. namespace.tenant.HCP.DOMAIN.com/rest/path

        String url = "http://example-namespace.example-tenant.example-domain/rest/examples/world.txt";

 

        HttpHead request = new HttpHead(url);

 

        //add authorization header for user(base64) "exampleuser" with password(md5) "password"

        request.addHeader(HCPAuthHeaderKey, auth);

 

        //execute the request

        HttpResponse response = client.execute(request);

 

        //print response status to console

        System.out.println("Response Code : "

                + response.getStatusLine().getStatusCode() + " " + response.getStatusLine().getReasonPhrase());

 

        //get response content

        BufferedReader rd = new BufferedReader(

                new InputStreamReader(response.getEntity().getContent()));

 

        //print response content to console

        StringBuffer result = new StringBuffer();

        String line = "";

        while ((line = rd.readLine()) != null) {

            result.append(line);

        }

        System.out.println(result.toString());

    }

I get a 200 response from this execution for the initial status code, but then I get a null pointer when I try to read the entity content a bit later.

The file does exist here and can be retrieved, but I'm not getting the expected system metadata repsonse I would expect which looks like this:

 

HTTP/1.1 200 OK
X-HCP-Time: 1259584200

Content-Length: 12
X-HCP-Type: object
