After successfully fetching alarms from Corba U2000 server and now reading the values, I am getting the error below

Or is my way of reading the alarms list incorrect? Thanks.

You can find the example method below for getAlarmList
//Connect to AlarmIRP
AlarmIRP alarmIRP = AlarmIRPHelper.narrow(orb.string_to_object(alarmIrpIOR.value));
StringTypeOpt alarmFilter = new StringTypeOpt();
alarmFilter.value("");
DNTypeOpt base_object = new DNTypeOpt();
base_object.value("");
BooleanHolder flag = new BooleanHolder(false); // false for iteration
AlarmInformationIteratorHolder iter = new AlarmInformationIteratorHolder();
List<String> alarmIds = get_alarm_list(alarmIRP, alarmFilter, base_object, flag, iter);
private List<String> get_alarm_list(org._3gppsa5_2.AlarmIRPSystem.AlarmIRP alarmIRP, org._3gppsa5_2.ManagedGenericIRPConstDefs.StringTypeOpt alarmFilter, org._3gppsa5_2.AlarmIRPConstDefs.DNTypeOpt base_object, BooleanHolder flag, org._3gppsa5_2.AlarmIRPSystem.AlarmInformationIteratorHolder iter) throws org._3gppsa5_2.AlarmIRPSystem.GetAlarmList, org._3gppsa5_2.ManagedGenericIRPSystem.ParameterNotSupported, org._3gppsa5_2.AlarmIRPSystem.NextAlarmInformations, org._3gppsa5_2.ManagedGenericIRPSystem.InvalidParameter, BAD_OPERATION {
logger.info("[get-alarm-list][start]");
alarmIRP.get_alarm_list(alarmFilter, base_object, flag, iter);
List<StructuredEvent> alarms = new ArrayList();
EventBatchHolder alarmInformation = new EventBatchHolder();
short alarmSize = 100;
List<String> alarmIds = new ArrayList();
while (iter.value.next_alarmInformations(alarmSize, alarmInformation)) {
alarms.addAll(Arrays.asList(alarmInformation.value));
logger.info("Current alarm size:" + alarms.size());
}
for (StructuredEvent event : alarms) {
try {
//printAlarm(event);
} catch (Exception ex) {
}
List<Property> rem = new ArrayList<Property>();
rem.addAll(Arrays.asList(PropertySeqHelper.extract(event.remainder_of_body)));
for (Property property : rem) {
if (!property.name.equals(org._3gppsa5_2.AlarmIRPNotifications.NotifyNewAlarm.ALARM_ID)) {
continue;
}
alarmIds.add(property.value.extract_string());
}
}
logger.info("[get-alarm-list][completed] size :" + alarms.size());
return alarmIds;
}

I managed to figure out what is that filterableData.value.toString() value that is "org.jacorb.orb.CDROutputStream". It turns out that the property with name "b" is a TimeBase:: UtcT according to the docs.
To convert it to correct value which is a utc timestamp, I changed the condition to
if (filterableData.name.equals("b") && filterableData.value != null && filterableData.value.toString().contains("org.jacorb.orb.CDROutputStream")) {
long occuranceTime = TimeTHelper.read(filterableData.value.create_input_stream());
System.out.println("data.value: " + occuranceTime);
}

Retrieve google contact profile picture

I need to retrieve google contacts information including contact's profile picture. To do this I use code below and everything works except contact's profile picture: the link that I get leads to nowhere. Is there any other way to get contact's profile picture link?
GoogleCredential gc = new GoogleCredential();
gc.setAccessToken(accessToken);
ContactsService contactsService = new ContactsService("ServiceName");
contactsService.setOAuth2Credentials(gc);
URL url = new URL("https://www.google.com/m8/feeds/contacts/default/full/?max-results=10000");
ContactFeed feed = null;
try {
feed = contactsService.getFeed(url, ContactFeed.class);
} catch (ServiceException e) {
e.printStackTrace();
}
List<SocialContact> contacts = new ArrayList<>();
if (feed != null) {
for (ContactEntry entry : feed.getEntries()) {
SocialContact contact = new SocialContact();
if (entry.hasName()) {
Name name = entry.getName();
if (name.hasFullName()) {
if (name.hasGivenName()) {
String givenName = name.getGivenName().getValue();
if (name.getGivenName().hasYomi()) {
givenName += " (" + name.getGivenName().getYomi() + ")";
}
contact.setFirstName(givenName);
if (name.hasFamilyName()) {
String familyName = name.getFamilyName().getValue();
if (name.getFamilyName().hasYomi()) {
familyName += " (" + name.getFamilyName().getYomi() + ")";
}
contact.setLastName(familyName);
}
}
}
}
for (PhoneNumber number : entry.getPhoneNumbers()) {
contact.setPhone(number.getPhoneNumber());
}
for (Email email : entry.getEmailAddresses()) {
contact.setEmail(email.getAddress());
}
contact.setProfileImageURL(entry.getContactPhotoLink().getHref());
if(contact.getEmail() != null){
contacts.add(contact);
}
}
}

It sounds like you are using the Contacts API but maybe you should use the People API instead. The code below is modified from these docs:
ListConnectionsResponse response = peopleService.people().connections().list("people/me")
.setPersonFields("names,emailAddresses,photos")
.setPageSize(10000)
.execute();
List<Person> connections = response.getConnections();
if (connections != null && connections.size() > 0) {
for (Person person : connections) {
List<Name> names = person.getNames();
if (names != null && names.size() > 0) {
System.out.println("Name: " + person.getNames().get(0)
.getDisplayName());
} else {
System.out.println("No names available for connection.");
}
List<Photo> photos = person.getPhotos();
if (photos != null && photos.size() > 0){
System.out.println("Photo URL: " + person.getPhotos().get(0).getURL());
}
}
} else {
System.out.println("No connections found.");

Store 'Data' in a HashMap after every Test Execution (TestNG Class)?

Is it possible to store all test cases which have failed in a hashmap, and then call all values stored in the map at the end of a class?
Variable:
private HashMap<String, Integer> serverStatusMap = new HashMap<String, Integer>();
After Method Code:
#AfterMethod
public void trackServerStatus(ITestResult testResult) {
if (testResult.getStatus() == ITestResult.FAILURE) {
try {
String testName = this.getClass().getSimpleName().toString();
int serverStatus = ServerStatus.getResponseCode(basePage.getCurrentURL());
int i = 0;
while(i < serverStatusMap.size()) {
serverStatusMap.put(testName, serverStatus);
i++;
}
//serverStatusMap.put(testName, serverStatus);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
Calling the stored values in the map After class:
#AfterClass
public void sendEmailBasedOnFailure(ITestContext context) throws WebDriverException, Exception {
String tempTime = new SimpleDateFormat("hh.mm.ss").format(new Date());
if(context.getFailedTests().size() > 0) {
SendEmailFile.sendEmailReport(
"TIME: " + tempTime + " | " + this.getClass().getPackage().toString(),
"TIME: " + tempTime + " | " + this.getClass().getPackage().toString() + " | " + "CLASS NAME: "
+ this.getClass().getSimpleName().toString() + "\n\n" +
"TOTAL NUMBER FAILED TESTS: " + context.getFailedTests().size() + "\n\n" +
"FAILED TEST CASES: " + context.getFailedTests().getAllMethods().toString() + "\n\n" +
serverStatusMap.toString());
}
Look at the last line of code: 'serverStatusMap.toString()'
Current Output of the Map:
{}

I do not understand what you are trying to do.
Do you want to send an email with failed tests?
Why not using the appropriate features like Listener or Reporter?
Have a look on the documentation about logging.

You have initialized variable "serverStatusMap". From below code
int i =0;
while(i < serverStatusMap.size()) {
serverStatusMap.put(testName, serverStatus);
i++;
}
I can see that i=0 and also serverStatusMap.size()=0. So it will never enter in while loop. so Finally when you print map there is nothing inside map. You need to change your while condition.

GenerateDataPDf method generates PDF based on the parameters i.e ProductType(GenMode),CrnList(uploaded in excel file...)Code works fine when only single user generates PDF. But If two different User(User and roles are assigned in application) start the process same time request paraeters are overridden then! Suppose first user request pdf for 50 customers for product 1. User1's process is still running and second user request for product2. Now User1's pdf are generated but for product2.....! Here batchId is unique for every single request.One table is maintained where batch_id,all pdf,generation flags are mainained there. How do I solve this?

As per your comment, this is what I would do, It's probably not the best way to do !
Firstly : Create a function to collet all your data at the beginning. You should not modify/update/create anything when you are generating a PDF. IE : array/list collectPDFData() wich should retourn an array/list.
Secondly : Use a synchronized methods like synchronized boolean generatePDF(array/list)
"Synchronized" methods use monitor lock or intrinsic lock in order to manage synchronization so when using synchronized, each method share the same monitor of the corresponding object.
NB : If you use Synchronize, it's probably useless to collect all your data in a separate way, but I think it's a good practice to make small function dedicated to a specific task.
Thus, your code should be refactored a little bit.

Handling SQL Null Parameters Elegantly

I'm generating an SQL statement by checking if each of the column fields submitted to the query are empty (== null) or not. It seems that my approach is pretty naive so I'm wondering what can be done about handling null parameters elegantly. When something isn't specified it should simply match anything.
Here is the code:
public List<Flight> findMatchingFlights(Flight flight)
{
List<Flight> foundFlights = new ArrayList<>();
StringBuilder sqlQueryBuilder = new StringBuilder();
sqlQueryBuilder.append("SELECT * FROM Flights");
boolean emptyQuery = true;
if(flight.getDeparture() != null)
{
if(emptyQuery)
{
sqlQueryBuilder.append(" WHERE ");
emptyQuery = false;
}
sqlQueryBuilder.append("Departure = '" + flight.getDeparture() + "'");
}
if(flight.getArrival() != null)
{
if(emptyQuery)
{
sqlQueryBuilder.append(" WHERE ");
emptyQuery = false;
}
else
{
sqlQueryBuilder.append(" AND ");
}
sqlQueryBuilder.append("Arrival = '" + flight.getArrival() + "'");
}
if(flight.getFlightNumber() != null)
{
if(emptyQuery)
{
sqlQueryBuilder.append(" WHERE ");
emptyQuery = false;
}
else
{
sqlQueryBuilder.append(" AND ");
}
sqlQueryBuilder.append("Number = '" + flight.getFlightNumber() + "'");
}
if(flight.getFlightMinutes() != 0)
{
if(emptyQuery)
{
sqlQueryBuilder.append(" WHERE ");
emptyQuery = false;
}
else
{
sqlQueryBuilder.append(" AND ");
}
sqlQueryBuilder.append("Duration = " + flight.getFlightMinutes());
}
/*
...
A bunch more fields
*/
if(flight.getAirplane() != null)
{
if(emptyQuery)
{
sqlQueryBuilder.append(" WHERE ");
}
else
{
sqlQueryBuilder.append(" AND ");
}
sqlQueryBuilder.append("Airplane = '" + flight.getAirplane() + "'");
}
sqlQueryBuilder.append(";");
// Execute sql and fill list with rows that match
}

You can create the common method for the below block and call the method by passing the arguments.
if(flight.getArrival() != null)
{
if(emptyQuery)
{
sqlQueryBuilder.append(" WHERE ");
emptyQuery = false;
}
else
{
sqlQueryBuilder.append(" AND ");
}
sqlQueryBuilder.append("Arrival = '" + flight.getArrival() + "'");
}

Best approach would be to do the trick in SQL than checking for null in Java. This is how you can do it.
sqlQueryBuilder.append("(Number = '" + flight.getFlightNumber() + "' OR " + flight.getFlightNumber() + " IS NULL)");
This way you wont have to check null in java, if the flight.getFlightNumber() is null then this where clause will always return true which is what you would want.
The only drawback to this method is that the clause will be included in the query, but since you are intending to use these columns to query the table incase they are not null, i would assume the table would be indexed likewise.

sqlQueryBuilder.append("SELECT * FROM Flights WHERE 1 = 1");
then you don't need emptyQuery flag and checks and many if else constractions.
List<Flight> foundFlights = new ArrayList<>();
StringBuilder sqlQueryBuilder = new StringBuilder();
sqlQueryBuilder.append("SELECT * FROM Flights WHERE 1 = 1");
if(flight.getDeparture() != null) {
sqlQueryBuilder.append("AND Departure = '" + flight.getDeparture() + "'");
}
