I am trying to store the latitude and longitude of a tweet in a JSON object. It works fine when I just use the geo location.
ex. obj.put("coordinates", tweet.getGeoLocation());
When I change it to get just the latitude or longitude is throws a null pointer exception.
ex. obj.put("lat", tweet.getGeoLocation().getLatitude());
Code:
JSONArray array = new JSONArray();
try {
Query query = new Query("query");
QueryResult result;
result = twitter.search(query);
tweets = result.getTweets();
for (Status tweet : tweets) {
JSONObject obj = new JSONObject();
obj.put("userName", tweet.getUser().getScreenName());
obj.put("text", tweet.getText());
obj.put("lat", tweet.getGeoLocation().getLatitude());
obj.put("lon", tweet.getGeoLocation().getLongitude());
String json = obj.toString();
array.put(obj);
}
System.out.println(array);
}
catch (TwitterException te) {
te.printStackTrace();
System.out.println("Failed to search tweets: " + te.getMessage());
System.exit(-1);
}
return array;
}
This is the error:
SEVERE: Servlet.service() for servlet [Jersey REST Service] in context with path [/Jersey] threw exception
java.lang.NullPointerException
Update: It seems to be half working now, it does actually get the latitude and longitude now, but there is still an error.
Here is the output log.

I think what happens is, the geolocation element for some of the tweets you're harvesting is null. There is nothing else there to possibly throw a NullPointerException unless the tweet itself is null, which doesn't seem to be the case since you don't get the exception if you store the GeoLocation element as is, without extracting longitude and latitude.
Also if you check the javadoc for the getGeolocation() method, you'll find that there is no obligation for a tweet to be geolocated and as such, the location can possibly be null:
/**
* Returns The location that this tweet refers to if available.
*
* #return returns The location that this tweet refers to if available (can be null)
* #since Twitter4J 2.1.0
*/
GeoLocation getGeoLocation();
I'd suggest doing the following and see if it solves your problem:
for (Status tweet : tweets) {
JSONObject obj = new JSONObject();
obj.put("userName", tweet.getUser().getScreenName());
obj.put("text", tweet.getText());
final GeoLocation location = tweet.getGeolocation();
if(location != null) {
obj.put("lat", location().getLatitude());
obj.put("lon", location().getLongitude());
}
String json = obj.toString();
array.put(obj);
}

and my controller looks like this
#Controller
public class RunReportFormController {
#RequestMapping(value = "/module/reporting/run/runReport.form", method = RequestMethod.GET)
protected String initializeForm(HttpServletRequest request, ModelMap model) throws Exception {
// Some logic
}
#RequestMapping(value = "/module/reporting/run/runReport.form", method = RequestMethod.POST)
protected String onSubmit(#ModelAttribute Object commandObject, BindException errors) throws Exception {
// some logic
}
Can someone help me understanding what have i done wrong here ? Thanks
Managed to fix it after changing the post method signature from BindException to BindingResult
#RequestMapping(value = "/module/reporting/run/runReport.form", method = RequestMethod.POST)
protected String onSubmit(#ModelAttribute Object commandObject, BindingResult errors) throws Exception {
This is the method of Dao class that is throwing Exception:
I did not used any Integer here. Even the phone number property is
also a String as it can contain +,() Symbols sometimes.
public List<StudentDetails> retriveStudents( String studentFirstName, String studentLastName,String studentEmail, String studentPhoneNum) {
logger.info("AddStudentDao retriveStudents():- START");
List<StudentDetails> nonTerminatedStudentsList = null;
//List<UserLocationMapping> userLocationMappings = null;
Set<Integer> studentIdSet = new HashSet<Integer>();
try {
DetachedCriteria objmCriteria = DetachedCriteria.forClass(StudentDetails.class);
//objmCriteria.createAlias("studentDetails", "UserDetails");
objmCriteria.add(Restrictions.ne("loginId", Constants.SUPER_ADMIN));
if (!Utilities.IsEmpty(studentFirstName)) {
objmCriteria.add(Restrictions.like("firstName", "%" + studentFirstName + "%"));
}
if (!Utilities.IsEmpty(studentLastName)) {
objmCriteria.add(Restrictions.like("lastName", "%" + studentLastName + "%"));
}
if (!Utilities.IsEmpty(studentEmail)) {
objmCriteria.add(Restrictions.like("email", "%" + studentEmail + "%"));
}
if (!Utilities.IsEmpty((studentPhoneNum))) {
objmCriteria.add(Restrictions.like("phoneNumber", "%" + studentPhoneNum + "%"));
}
nonTerminatedStudentsList = hibernateTemplate.findByCriteria(objmCriteria);//*****EXCEPTION RAISING*****(Line number 216)
if (studentIdSet != null && studentIdSet.size() > 0) {
nonTerminatedStudentsList = getStudents(studentIdSet);
}
} catch (Exception e) {
logger.error(" AddStudentDao retriveUsers :- ", e);
}
logger.info("AddStudentDao retriveUsers():- END");
return nonTerminatedStudentsList;
}
This is supposed to return a List of StudentDetails objects but the
method used in this scenario is raising an Exception. Hope somebody
can help me.
and the exception is shown like this:

Sorry guys.. My bad.
the constant in the first Restriction is an integer.
Thank you.
I may refer to an existing question here on Stackoverflow: Error during Table cache update in vaadin
First things first: I'm using Vaadin 7.5.2 running on Apache Tomcat v7.0.
For some magic reason (and I don't really understand what's the difference between my usual code) the addItem function on a vaadin table gives me an exception ("Error during cache update"). There is an inner exception aswell as follows:

Some code for you
OrderListComponent.java:83
private void updateInformation() {
Table orderTable = getOrderTable();
orderTable.setCacheRate(0.0);
orderTable.select(null);
orderTable.setValue(null);
orderTable.removeAllItems();
orderTable.clear();
for (Order order : getOrders()) {
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
Product product = order.getProduct();
Object[] cells = new Object[] { product.getName(), simpleDateFormat.format(order.getCreationDate()),
simpleDateFormat.format(order.getUpdateDate()), order.getOrderStatus().toString(),
order.getPrice() };
orderTable.addItem(cells, new Integer(orderTable.size()));
}
if (getOrders().size() > 8) {
orderTable.setPageLength(8);
}
}
CustomerInfoComponent.java:121
orderStatusSelection = new OrderStatusSelectionComponent(getController(), new OrderStatusChangedListener() {
#Override
public void orderStatusChanged(OrderStatus status) {
if (getSelectedOrder().getProduct().getName().startsWith("happy") && status == OrderStatus.ACTIVE
&& getController().checkForEquivalentProduct("happy")) {
Notification.show(
"Sie haben bereits eine Bestellung dieser Art. Deaktivieren Sie diese, bevor Sie fortfahren.");
orderStatusSelection.setValue(OrderStatus.CANCELED.getValue());
} else {
getSelectedOrder().setOrderStatus(status);
getController().updateOrder(getSelectedOrder());
getController().updateCustomerInfoOrders();
}
}
}, getSelectedOrder().getProduct().getName().startsWith("happy"));
My orders table is initialized like this
orderTable = new Table("Bestellungen");
orderTable.addContainerProperty(COLUMN_NAME, String.class, "");
orderTable.addContainerProperty(COLUMN_CREATION_DATE, String.class, "");
orderTable.addContainerProperty(COLUMN_LAST_MODIFIED_DATE, String.class, "");
orderTable.addContainerProperty(COLUMN_STATUS, String.class, "");
orderTable.addContainerProperty(COLUMN_PRICE, Float.class, "");
orderTable.setPageLength(4);
orderTable.setSizeFull();
orderTable.setColumnReorderingAllowed(true);
orderTable.setColumnCollapsingAllowed(true);
orderTable.setColumnReorderingAllowed(true);
orderTable.setSelectable(true);
orderTable.setMultiSelect(false);
orderTable.setNullSelectionItemId(null);
I really hope someone can help me with this;
I'm totally stuck..
You have invalid default value for price column - it should be the same type as the column type, not String. Try:
orderTable.addContainerProperty(COLUMN_PRICE, Float.class, null);
or
orderTable.addContainerProperty(COLUMN_PRICE, Float.class, 0f);
I have Java Spring MVC application. I am trying to do CRUD on one table, say Employee.
When I am trying to create a new Employee, it saves and adds a new entry in database. But when I am trying to update an Employee, I am updating that row, and I am trying to add a new row, with the old values of the same employee and setting one field to false.
Here is my ServiceImpl
public class EmployeeServiceImpl extends
GenericManagerImpl<Employee, Long> implements
EmployeeService {
#Override
public void save(Employee employee) {
Employee newEmpl = employee;
Date date = new Date();
Long empKey = employee.getEmpKey();
if (empKey) != null) {
oldEmp = (Employee) employeeDao.get();
oldEmp.setActive(false);
oldEmp.setEmpKey(null);
employeeDao.save(oldEmp);
} else {
employee.setCreated(date);
}
employee.setUpdated(date);
employee.setActive(true);
employeeDao.save(employee);
}
}
When I am creating a new entry, it is working fine. But when I am trying to update one entry, then it showing the exception
org.springframework.orm.hibernate4.HibernateSystemException: identifier of an instance of com.table.model.Employee was altered from 4 to null; nested exception is org.hibernate.HibernateException: identifier of an instance of com.table.model.Employee was altered from 4 to null

I have checked this SO question, but they are using Query. My logic is in the Service Impl and not in DAO.
How can I alter the id and save as a new entry in database?
Thanks.
You shouldn't do that - it's in the JPA spec somewhere that one must not change a primary key.
What you could do is add a clone/copy method to your Employee class and use that to copy everything but the ID and then persist that new object.
Cheers,
This code below throws IllegalStateException: Cannot forward after response has been committed :
private void doRequest(HttpServletRequest request) throws IOException, ServletException {

ResultSet rs = null;
String someString;
try {
this.connectDB();

stmt.setLong(1, someFunc());
rs = stmt.executeQuery();
while (rs.next()) {
if (rs.getInt(1)==someOtherFunc()) {
someString = rs.getString(2);
break;
}
}
stmt = conn.prepareCall("{call sp_someSP(?, ?)}");
stmt.setLong(1, someFunc());
stmt.setTimestamp(2, new Timestamp(getFrom().getTime()));
rs = stmt.executeQuery();
if (rs.next()) {

LOGGER.error("Database connection closing failed", e);
}
}
In the JSP page there is this code so the page will refresh:
<meta http-equiv="Refresh" content="10">
The catch is that, the error does not happen most of the time, only when I access the Servlet that forward to the JSP, in multiple browser or tabs, and still not always, there is just a time that the error will hit.
What could be the problem?

doGet:
#Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
super.doGet(request, response);
doRequest(request);
}
Your doGet() is broken. You should remove the super.doGet(request, response); line. It's namely by default returning a "HTTP 405 Method Not Allowed" error page which effectively commits your response.
#Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doRequest(request);
}
Do not call the super.doXxx() method in servlets. They return by default a HTTP 405 error indicating that the method is not available (as per the Template Method pattern).
