        wr.Method = "GET";
        WebResponse res = wr.GetResponse();
        string resStr
         = new System.IO.StreamReader(res.GetResponseStream()).ReadToEnd();

        XNamespace atomNS

    _urlConn.addRequestProperty("UniqueUserID", uniqueId);
    BufferedReader br = new BufferedReader(new InputStreamReader(_urlConn.getInputStream()));
    String line = null;
    StringBuilder strBuilder = new StringBuilder();
    while ((line = br.readLine()) != null) {
      strBuilder.append(line);
      System.out.println(line);
    }
}

String[] IProperties = strBuilder.toString().split("<m:properties>");
    for (String str : IProperties) {
      Business business = new Business();
      business.setBusinessID(Utils.getStringBetween(str,"<d:BusinessID m:type="Edm.Int32">","</d:BusinessID>"));
