QuickBooks NULL CallbackHandler

I'm trying to perform a batch operation in QuickBook but getting null callbackhandler.
private static void AddBulkCustomer(DataService ds) throws FMSException{
BatchOperation bo = new BatchOperation();
Customer c1 = new Customer();
c1.setGivenName("Customer 3");
c1.setDisplayName("Disp Customer 3");
EmailAddress email = new EmailAddress();
email.setAddress("customer1#zzz.com");
c1.setPrimaryEmailAddr(email);
bo.addEntity(c1, OperationEnum.CREATE, "b3");
c1= null;
c1 = new Customer();
c1.setGivenName("Customer 4");
c1.setDisplayName("Disp Customer 4");
email = null;
email = new EmailAddress();
email.setAddress("customer2#z2zz.com");
c1.setPrimaryEmailAddr(email);
bo.addEntity(c1, OperationEnum.CREATE, "b4");
// String strQuery = " select * from customer where givenname ='"+c1.getGivenName()+"'";
// bo.addQuery(strQuery, "b3Query");
ds.executeBatchAsync(bo, new AsyncCallBackBatch());
}
For AsyncCallback operation
public class AsyncCallBackBatch implements CallbackHandler {
#Override
public void execute(CallbackMessage callbackMsg) {
System.out.println("asyncCallbackBatch is executing... ");
try {
System.out.println("QR = "+callbackMsg.getFMSException().toString());
BatchOperation BO = callbackMsg.getBatchOperation();
if (BO != null) {
List<String> bId = BO.getBIds();
for (String strBId : bId) {
if (BO.isFault(strBId)) {
Fault fault = BO.getFault(strBId);
System.out.println("asyncCallBackBatch Error Code : "+ fault.getError().get(0).getCode() + " "+ "Error : "
+ fault.getError().get(0).getDetail()+ ", Message : "+ fault.getError().get(0).getMessage());
} else if (BO.isEntity(strBId)) {
System.out.println("Batch having entity message.. ");
Customer cust = (Customer) BO.getEntity(strBId);
System.out.println("cust id : " + cust.getId()+ " CustName = " + cust.getGivenName());
} else if (BO.isQuery(strBId)) {
System.out.println("Batch having Query ... Parsing... ");
QueryResult qR = BO.getQueryResponse(strBId);
System.out.println("Query : " + qR.getTotalCount());
} else if (BO.isReport(strBId)) {

System.out.println(" " + report.getClass().getName());
} else {
System.out.println("Something went wrong... ");
}
}
}else{
System.out.println("Batch Operation terminated, reason: NULL callbackMsg ");
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
public static void main(String[] args) {
OAuthAuthorizer oAuth = new OAuthAuthorizer(consumerKey, consumerSecret, accessToken, accessTokenSecret);
//403352746
try {

System.out.println("RealmID : "+context.getRealmID());
context.setCustomerRequestTimeout(99999);
System.out.println("TimeOut Set to = "+context.getCustomerRequestTimeout());
System.out.println("BASE_URL_QBO = "+Config.getProperty(Config.BASE_URL_QBO));
Config.setProperty(Config.BASE_URL_QBO, "https://sandbox-quickbooks.api.intuit.com/v3/company");

DataService ds = new DataService(context);
AddBulkCustomer(ds);
System.out.println("Operation Complete..");
} catch (Exception e) {
e.printStackTrace();
}
}
When I debug, in execute method, I'm getting Null BatchOperation in return. I'm not sure performing Batch operation is allowed in sandbox environment.

I found the solution after so much of testing and communication with Quickbooks Devs thought would be helpful for others.
In sandbox environment even if you set the config properties to sandbox URL it still picks as PROD URL in Callbackhandler.
Config.setProperty(Config.BASE_URL_QBO, "https://sandbox-quickbooks.api.intuit.com/v3/company");
In this case they called this as a bug, currently all you can do is to make a trial account in PROD and then test this.

GCM Client in Java not working

I want to create an android GCM sender which will send the URL to the Android app. I have used this windows application to test my android app and it is working. I checked the code in C# and tried to convert it in Java. But I am not getting anything. Let me know what I am missing.

I just started working on Android. So kindly let me know if there are any relevant suggestions as well.
Input:

In Console, I am getting:
payload : {{"registration_ids" : ["device_id"],"data" : {{ "key" : "http://upload.wikimedia.org/wikipedia/commons/2/23/Lake_mapourika_NZ.jpeg" }}}}

EDIT
Your payload message inside AssembleJSONPayload is not formatted correctly. Please use following code to build payload:
String payloadFormatJSON =
"{" +
"\"registration_ids\" : [\"" + gcmDeviceToken + "\"]," +
"\"data\" : {" +
" " + gcmBody + " " +
"}" +
"}";
Output should be:
payload : {"registration_ids" : ["gcmDeviceToken value"],"data" : {"gcmBody value"}}

Authenticate an Active Directory user with UnboundID using username

I'm building an application where I need to connect to Active Directory using UnboundID. Using an example, I managed to connect a user with their distinguishedName and password.
However I would like to authenticate them using only the domain and the username, similar to how it's done in Windows. Browsing AD using a tool called JXplorer it seems like the sAMAccountName might be the property I need. However replacing the distinguishedName with the sAMAccountName resulted in an AcceptSecurityContext error. Using the "uid=..." syntax shown in the example also yielded the same error.
Is there a way to logon using only the domain, username/sAMAccountName and password. or do I somehow need to search through AD and find the distinguishedName of the user I wish to authenticate, and then bind the connection using their distinguishedName and password?

As #ioplex said in his comment, AD accepts a bind using the username from the sAMAccountName with the domain name appended to it. Just use it instead of the DN on the bind:
String userId = username + "#" + domain;
SimpleBindRequest adminBindRequest = new SimpleBindRequest(userId, passsword);
The final userId will be something like 'eharris#contoso.local'

You will need to use an account with appropriate permissions to perform a search for samAccountName to locate the user and then bind as the found user using the Distinguished Name.
You need to be sure you only return one entry from the search.

Unrecognized temporary token when attempting to complete authorization: FITBIT4J

I am trying to create a app for fitbit using fitbit4j . I found their sample code
at
https://github.com/apakulov/fitbit4j/blob/master/fitbit4j-example-client/src/main/java/com/fitbit/web/FitbitApiAuthExampleServlet.java
When i tried to implement it I am getting many errors.
below is their doGet function()
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
FitbitAPIClientService<FitbitApiClientAgent> apiClientService = new FitbitAPIClientService<FitbitApiClientAgent>(
new FitbitApiClientAgent(apiBaseUrl, fitbitSiteBaseUrl, credentialsCache),
clientConsumerKey,
clientSecret,
credentialsCache,
entityCache,
subscriptionStore
);
if (request.getParameter("completeAuthorization") != null) {
String tempTokenReceived = request.getParameter(OAUTH_TOKEN);
String tempTokenVerifier = request.getParameter(OAUTH_VERIFIER);
APIResourceCredentials resourceCredentials = apiClientService.getResourceCredentialsByTempToken(tempTokenReceived);
if (resourceCredentials == null) {
throw new ServletException("Unrecognized temporary token when attempting to complete authorization: " + tempTokenReceived);
}
// Get token credentials only if necessary:
if (!resourceCredentials.isAuthorized()) {
// The verifier is required in the request to get token credentials:
resourceCredentials.setTempTokenVerifier(tempTokenVerifier);
try {
// Get token credentials for user:
apiClientService.getTokenCredentials(new LocalUserDetail(resourceCredentials.getLocalUserId()));
} catch (FitbitAPIException e) {
throw new ServletException("Unable to finish authorization with Fitbit.", e);
}
}
try {
UserInfo userInfo = apiClientService.getClient().getUserInfo(new LocalUserDetail(resourceCredentials.getLocalUserId()));
request.setAttribute("userInfo", userInfo);
request.getRequestDispatcher("/fitbitApiAuthExample.jsp").forward(request, response);
} catch (FitbitAPIException e) {
throw new ServletException("Exception during getting user info", e);
}
} else {

response.sendRedirect(apiClientService.getResourceOwnerAuthorizationURL(new LocalUserDetail("-"), exampleBaseUrl + "/fitbitApiAuthExample?completeAuthorization="));
} catch (FitbitAPIException e) {
throw new ServletException("Exception during performing authorization", e);
}
}
}
When i run the code it goes into the 'else' part first and i get the URL with
localhost:8080/fitbitApiAuthExample?completeAuthorization=&oauth_token=5bccadXXXXXXXXXXXXXXXXXXXXXXXXXX&oauth_verifier=h35kXXXXXXXXXXXXXXXXX, and i get the fitbit login screen and when i log in
and since the
'completeAuthorization==null',
it is executing the else part again.So i manually added a value so that it will enter the 'if' section .
So the new URL became
localhost:8080/fitbitApiAuthExample?completeAuthorization=Success&oauth_token=5bccadXXXXXXXXXXXXXXXXXXXXXXXXXX&oauth_verifier=h35kXXXXXXXXXXXXXXXXX and entered the 'if' section.
Now am getting the exception
'Unrecognized temporary token when attempting to complete authorization:'I tried many workarounds but still cant understand the error.
Please Help.

Solved the problem. the 'apiClientService' was going null when i reload the servlet. Made it member variable and everything started working.

why you comment this line out?
//TrajetModel trajet = new TrajetModel();
I see no other line where you create the TrajetModel.
If that object is not initiated you get the NPE here:
trajet.setNom(aeroport.text());
