1. Please find my sample code:-
private static JSONObject invokeRPC() {
@SuppressWarnings("deprecation")
DefaultHttpClient httpclient = new DefaultHttpClient();
System.out.println("invokeRPC");
JSONObject json = new JSONObject();
JSONObject responseJsonObj = null;
try {
httpclient.getCredentialsProvider().setCredentials(
new AuthScope("172.17.0.2", 7742),
new UsernamePasswordCredentials("multichainrpc",
"Cojw4D6uo9fLnKdGLj7qH9WNqLftqXi15hWLhXt9q2HC"));
StringEntity myEntity = new StringEntity(json.toJSONString());
System.out.println(json.toString());
HttpPost httppost = new HttpPost(
"http://multichainrpc:Cojw4D6uo9fLnKdGLj7qH9WNqLftqXi15hWLhXt9q2HC@172.17.0.2:7742");
httppost.setEntity(myEntity);
System.out.println("executing request" + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (entity != null) {
System.out.println("Response content length: "
+ entity.getContentLength());
// System.out.println(EntityUtils.toString(entity));
}
JSONParser parser = new JSONParser();
responseJsonObj = (JSONObject) parser.parse(EntityUtils
.toString(entity));
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return responseJsonObj;
}
2. My node details are below:-

Please let me know the resolution for the same. Would be very helpful.
