Oracle MAF-MCS API call

Question

I have created a custom POST api for getting login information in MCS. when i check in SOAPUI it works perfectly fine. the parameters passed are

1. header   
Oracle-Mobile-Backend-Id: ********************
2. Authentocation
Username:****************
password: **************

and basic login info username and password as "User1" and "user1" respectively.

Step2:

when i call the API from MAF i am getting an error 400 the post method used is

    public static Response callPost(String restURI, String jsonRequest) {
    String responseJson = "";
    Response response = new Response();

    RestServiceAdapter restServiceAdapter = Model.createRestServiceAdapter();
    restServiceAdapter.clearRequestProperties();
    //restServiceAdapter.setConnectionName("MiddlewareAPI");
   // restServiceAdapter.setConnectionName("");


    restServiceAdapter.setRequestType(RestServiceAdapter.REQUEST_TYPE_POST);
    restServiceAdapter.addRequestProperty("Content-Type", "application/json");
    restServiceAdapter.addRequestProperty("Accept", "application/json; charset=UTF-8");
    restServiceAdapter.addRequestProperty("Oracle-Mobile-Backend-Id", "**********");
    restServiceAdapter.addRequestProperty("Domain", "mcsdem0001");


    restServiceAdapter.addRequestProperty("Username", "******");
    restServiceAdapter.addRequestProperty("Password", "*****");
    //restServiceAdapter.addRequestProperty("Authorization", "Basic "+new String(encodedBytes));
    System.out.println("**** Authorization String ****=>"+new String(encodedBytes));
    System.out.println("**** RestURI ******=>"+restURI);
    System.out.println("**** jsonRequest ******=>"+jsonRequest);

    restServiceAdapter.setRequestURI(restURI);
    restServiceAdapter.setRetryLimit(0);

    try {
        responseJson = restServiceAdapter.send(jsonRequest);
        int responseCode = restServiceAdapter.getResponseStatus();
        response.setResponseCode(responseCode);
        response.setResponseMessage(responseJson);
        response.setHeader(restServiceAdapter.getResponseHeaders());
    } catch (Exception e) {
        int responseCode = restServiceAdapter.getResponseStatus();
        response.setResponseCode(responseCode);
        response.setResponseMessage(responseJson);
    }
    System.out.println("Response:" + responseJson);

    return response;
}

Could anyone please tell me is there any error in the post method??

actually this bit

restServiceAdapter.addRequestProperty("Username", "******"); restServiceAdapter.addRequestProperty("Password", "*****");

doesn't work because you attempt to pass username and password as a HTTP header. Instead it should be passed as you were trying here

restServiceAdapter.addRequestProperty("Authorization", "Basic "+new String(encodedBytes));

However, these should not be encoded bytes but a base64 encoded string in the form

Basis (without the < abd >)

Note that user identity domains only need to be provided in multi-tenant environments. In MCS, the user domain is defined through the mobile backend you connect to.

This can be due to the version conflict. Try to use HttpUrlConnection instead of RestServiceAdapter and let me know if it works.

Use the MAF MCS Utility library to make it allot easier. The developer guide can be found here: http://download.oracle.com/otn_hosted_doc/maf/mafmcsutility-api-doc-082015.pdf

Example code:

MBEConfiguration mbeConfiguration = 
    new MBEConfiguration(
          <mbe rest connection>,<mobileBackendId>,
          <anonymous key string>,<application key string>, 
          MBEConfiguration.AuthenticationType.BASIC_AUTH);
 mbeConfiguration.setEnableAnalytics(true);
 mbeConfiguration.setLoggingEnabled(false)
 mbeConfiguration.setMobileDeviceId(
         DeviceManagerFactory.getDeviceManager().getName());
 MBE mobileBackend = MBEManager.getManager().
         createOrRenewMobileBackend(<mobile backend Id>, mbeConfiguration);

CustomAPI customApiProxy = mbe.getServiceProxyCustomApi();
MCSRequest request = new MCSRequest(mobileBackend.getMbeConfiguration());

request.setConnectionName(<Rest connection name>);
request.setRequestURI("/moile/custom/mockup/employees");
request.setHttpMethod(MCSRequest.HttpMethod.POST);
request.setPayload("{\"id\":\"1\"\"name\":\"nimphius\",\"firstName\":\"frank\"}");
request.setRetryLimit(0);
HashMap<String, String> headers = new HashMap<String, String>();
headers.put("Content-Type","application/json");
request.setHttpHeaders(headers);
MCSResponse response = customApiProxy .sendForStringResponse(request);
String jsonResponse = (String) response.getMessage();

The developer guide explains how to use. The sample code I provided also comes from that document. — User404, Sep 22 '15 at 08:48
Thats Ok.. could you please tell me whether is there any problem with my code? — Arj 1411, Sep 22 '15 at 10:08
I have followed the steps, but i got an error:: HTTP Status Code 401 Unauthorized: The request requires user authentication. The response MUST include a WWW-Authenticate header field containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field. — Arj 1411, Sep 23 '15 at 07:41
