I am trying to create a TableView in JavaFX, but after many attempts values are not showing without giving any Errors.
If i create a TableView with only one Object declared (TableView) it works properly.
I already tried to create a "helper" class, which contained both objects as it's attributes, but still the same problem no errors just TableView not working.
Any suggestions how to fix this?
Here is what i am trying to do:
public TableColumn<CarEntity, String> HistoryBrand;
public TableColumn<CarEntity, String> HistoryColor;
public TableColumn<CarEntity, Date> HistoryDate;
public TableColumn<CarEntity,String> HistoryCategory;
public TableColumn<CarEntity,Double> HistoryPrice;
public TableColumn<OrdersArchiveEntity, Integer> HistoryCarScore;
public TableColumn<OrdersArchiveEntity, Integer> HistoryOrderScore;
public TableColumn<OrdersArchiveEntity, Date> HistoryRentalDate;
public TableColumn<OrdersArchiveEntity, Date> HistoryReturnDate;
public TableView HistoryTable;
HistoryBrand.setCellValueFactory(new PropertyValueFactory<CarEntity, String>("mark"));
HistoryColor.setCellValueFactory(new PropertyValueFactory<CarEntity,String>("color"));
HistoryDate.setCellValueFactory(new PropertyValueFactory<CarEntity, Date>("productionDate"));
HistoryCategory.setCellValueFactory(new PropertyValueFactory<CarEntity, String>("category"));
HistoryPrice.setCellValueFactory(new PropertyValueFactory<CarEntity, Double>("price"));
HistoryCarScore.setCellValueFactory(new PropertyValueFactory<OrdersArchiveEntity,Integer>("carScore"));
HistoryOrderScore.setCellValueFactory(new PropertyValueFactory<OrdersArchiveEntity,Integer>("orderScore"));
HistoryRentalDate.setCellValueFactory(new PropertyValueFactory<OrdersArchiveEntity,Date>("rentalDate"));
HistoryReturnDate.setCellValueFactory(new PropertyValueFactory<OrdersArchiveEntity,Date>("returnDate"));
Query queryHist = session.createQuery("select c, o from OrdersArchiveEntity o, CarEntity c where c.id=o.carByCarId.id");
List HistoryList = queryHist.list();
ObservableList Historia = FXCollections.observableArrayList(HistoryList);
HistoryTable.setItems(Historia);
And here are my Classes

For the previous week or so, I have been fruitlessly trying to get this JPA library to work.
I can perform simple queries, e.g. find entity by id, or get a collection of entities, etc, however, when I try to perform more complex queries, I always seem to be encounter an error. Can someone please help with debugging this COUNT statement which produces the following stack trace of errors:
Caused by: org.hibernate.query.sqm.InterpretationException: Error interpreting query [SELECT COUNT(a.id) FROM AgreementEntity a]; this may indicate a semantic (user query) problem or a bug in the parser
Caused by: java.lang.NullPointerException
Here is the code which causes the error:
EntityManager em = getFirstEntityManager();
Session session = em.unwrap(Session.class);
// The following line of code causes an error
session.createQuery("SELECT COUNT(a.id) FROM AgreementEntity a");
And here is the entire AgreementEntity class:

You can try count(a) instead of a.id
EntityManager em = getFirstEntityManager();
Session session = em.unwrap(Session.class);
// The following line of code causes an error
session.createQuery("select count(a) from AgreementEntity a ");
Same problem here with count function and group by. I downgraded to 5.4.10.Final version to make it work.
The issue was that I was using an alpha build of the hibernate library instead of a stable build.
I connected my MySql database to my Java project (using Spring-MVC) with Entities.
When I try to run the application, I get this error:

Ordersitems connects between Orders and Products - it contains the products of each order, so productId and orderId both foreign keys in Orderitems.
I think I understand the error, if I'm not wrong, the reapeted column error refers to:
#Id
#Column(name = "orderId", nullable = false, insertable = false, updatable = false)
public String getOrderId() {
return orderId;
}
and:
#ManyToOne
#JoinColumn(name = "orderId", referencedColumnName = "orderId", nullable = false)
public OrdersEntity getOrdersByOrderId() {
return ordersByOrderId;
}
public void setOrdersByOrderId(OrdersEntity ordersByOrderId) {
this.ordersByOrderId = ordersByOrderId;
}
But whatever I tried to do didn't solve the problem or even added other errors.
Can you please help me to solve this problem?
Thanks!
I know this might be a common problem but so far I couldn't find any solution.
I have the following 2 entities: Mission and Representation. Both entities have composed primary keys, respectively:
MissionId [idImpXml, code, categorie]
RepresentationId [idImpXml, codeRepresentation]
There's a one-to-many relationship between Representation and Mission, meaning that each mission has a single representation and each representation can be used in different missions.
I use JPA repositories to persist the entities in my database:
public interface RepresentationDao extends JpaRepository <Representation, RepresentationId>
public interface MissionDao extends JpaRepository <Mission, MissionId>
I need to save first a set of representations, and THEN a set of missions.
The representations work correctly, but when I try to save a mission the foreign key to the representation remains empty.
This is my code:
// here representations are already persisted (in a separate transaction)..
RepresentationId representationId = new RepresentationId(idImpXml, codeRepresentation);
Representation representation = representationDao.findOne(representationId);
// representation is retrieved correctly
MissionId missionId = new MissionId(idImpXml, code, categorie);
Mission mission = new Mission(missionId, representation, label);
// I try to save the mission
missionDao.saveAndFlush(mission);
// THE FOREIGN KEY THAT SHOULD REFERENCE THE REPRESENTATION (CODE_REPRESENTATION) REMAINS NULL
Mission

}
public void setContentA(String contentA) {

}

#Entity
#Table(name = "B")

}
#Basic

public String getContentB() {
return contentB;
}
public void setContentB(String contentB) {
this.contentB = contentB;
}
}
C.java
#Entity
#Table(name = "C")
public class C {
private long id;

private A a;
#ManyToOne(fetch = FetchType.EAGER)

}
public void setContentC(String contentC) {

}
the problem is sometimes I just want to get A with List<B>, in another time I want to get A with List<C>. Is there any way I can do this by hibernate?

Each time when I query the chapter list, I get all the sub list. Even when I set a breakpoint in the end of method chapterEntityList() of my service layer, I also get all the sub list. I also tried query a list use hql, but it still didn't work.
Change FetchType.EAGER to FetchType.LAZY in your #OneToMany annotations. This will casue Hibernate to load a collection only when you directly refer to it.
i have a program that communicates with an existing database. There is a composite table that has an employee and a vehicle as its composite key. On the edit or add employee page, their is a dropdown box to select which vehicles the employee prefers and then stores the vehicle list in a hashtable in the employee class. However, the list will not persist, or store, in the composite table. I am new to seam and have spent all day trying to figure this out. Any help would be appreciated.
Here are some of my classes:

If any more info is needed please let me know. Any help will be greatly appreciated. thank you
First of all, check your code, you have a lot of buggy instructions: in Java you compare Strings with the equals() method, not like this: ssn != "".
The root of your problem is not Seam itself but Hibernate. First of all, add elements to the vehicle set via n.getFlowerStoreVehicles().add(...), don't reassign the entire set with n.setFlowerStoreVehicles(...) (this is probably not a problem during entity creation but becomes a problem when modifying the set after the entities are persisted.
The reason for the relationship not being correctly persisted is that FlowerStoreEmployee is the "weak" side of the relationship (the one with the "mappedBy" attribute in the annotation). Move the #JoinTable annotation to the FlowerStoreEmployee class and remove it from FlowerStoreVehicle, remove the mappedBy from FlowerStoreEmployee and put it in the FlowerStoreVehicle (mappedBy="flowerStoreVehicles"). Since the relationship is bi-directional, assign to both sides of the relationship:
FlowerStoreVehicle veh = entityManager.find(FlowerStoreVehicle.class, vehId);
veh.getFlowerStoreEmployees().add(n); // one direction: vehicle -> employee
n.getFlowerStoreVehicles().add(veh); // the other direction: employee -> vehicle
There is no entityManager.persist at the end of your code, apart from persisting the ZipCode no Object is persisted.
