Here is My Code

void ObjectOpenStack4j() throws JSONException, ParseException {
        JSONParser parser = new JSONParser();
        Object obj;
        JSONArray vcapArray;
        JSONObject jsonObject
                ,vcap
                ,credentials;
        String envServices,username = null,password = null,auth_url = null,
domain = null,project = null;

        Identifier domainIdent,projectIdent;

        String envApp = System.getenv("VCAP_APPLICATION");
        System.out.println("VCAP_APPLICATION - " + envApp);
        envServices = System.getenv("VCAP_SERVICES");
        System.out.println("VCAP_SERVICES - " + envServices);

        if (envServices != null && envServices.length() > 0) {
//
        obj = parser.parse(envServices);

        System.out.println("Result: "+obj.toString());

        jsonObject = (JSONObject) obj;
        vcapArray = (JSONArray) jsonObject.get("Object-Storage");
        vcap = (JSONObject) vcapArray.get(0);
        credentials = (JSONObject) vcap.get("credentials");

            username = credentials.get("username").toString();
            password = credentials.get("password").toString();
            auth_url = credentials.get("auth_url").toString() + "/v3";
            domain = credentials.get("domainName").toString();
            project = credentials.get("project").toString();

        }else{
            username = "xxxxxxxxxxxxxxxxxx";
            password = "xxxxxxxxxxxx";
            auth_url = "https://xxxxxx.open.xxxxxx.com";
            domain = "12345";
            project = "xxxxxxxxxxxxxxxxxx";
        }


        domainIdent = Identifier.byName(domain);
        projectIdent = Identifier.byName(project);


        OSClient os = OSFactory.builderV3().endpoint(auth_url).
credentials(username, password, domainIdent).scopeToProject(projectIdent, 
domainIdent)
                .authenticate();
        SwiftAccount  account = os.objectStorage().account().get();
        System.out.println("Result: "+account);

    }
