TableView not showing values when using two Objects JAVAFX with Hibernate

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

Persisting a table with foreign keys using EJB and JPA

I am new to JavaEE and I am having a problem with persisting a table that has foreign keys pointing to the primary key of another table using entity classes and ejb's entity manager. I am using Netbeans.
I have an entity called 'property' and have another entity called 'offer' which holds the foreign key pointing to the primary key of the property. So basically, the logic is that one property can have many offers. Therefore, I am trying to add new offers in the 'offer' table using the entity manager but I am not being able to do it. You can look at the code and see what I maybe missing.

Servlet that connects the JSP with the EJB:
String action = request.getParameter("action");
String currencyType = request.getParameter("ddlCurrencyType");
String amount = request.getParameter("offerAmount");
String propertyIdStr = request.getParameter("hdnbt");
if ("Offer".equalsIgnoreCase(action))
{
if ("".equals(action) & !"".equals(currencyType) & !"".equals(amount) & !"".equals(propertyIdStr))

Date currentTime = new Date();
int propertyId = Integer.parseInt(propertyIdStr);
try {

currentTime = df1.parse(df1.format(currentTime));
} catch (ParseException e) {
}
Buyer buyer = buyerDAO.GetBuyer(1);
Property property = propertyDAO.GetProperty(propertyId);
Offer offer = new Offer("Pending", amount, amount, currentDate, currentTime, buyer, property);
offerDAO.Add(offer);
}
else
{
}
}
request.setAttribute("allProperty", propertyDAO.GetAllProperty());
request.getRequestDispatcher("AdministerProperty.jsp").forward(request, response);
Am I missing something here? I have followed a tutorial which didn't have a foreign key guidance but tried to use my own logic to go around it but it didn't work. I cannot find a reliable source that uses the method similar to me. Most of the resources I find are for Hibernate but I am using EJB.

It seems that the method which retrieves the Property and the method that persists the Offer are run in a separate transactions (DAOs being the Stateless session beans).
That would mean that the Offer is populated and persisted with a detached Property, so the persistence provider is not aware of it.
Not sure why an exception is not raised but you would have to merge the Property first or do the query in the same transaction as you persist the Offer:
#Override
public void Add(Offer offer, int peropertyId) {
Property property = em.find(Property.class, propertyId);
offer.setPeropertyId(property);
em.persist(offer);
}
or
#Override
public void Add(Offer offer, Property peroperty) {
Property managedProperty = em.merge(property);
offer.setPeropertyId(managedProperty);
em.persist(offer);
}

I fixed it. If you look at the code for servlet, it was the problem with my if condition that checks the action parameter. It was meant to be if action is not empty but it checks if action is empty. I found this issue by creating an integer that increments itself when it reaches certain stages within the code.
I think you were right on the fact that I had to do the getting property id and buyer id on the same transaction. Otherwise that would have been the next issue for me. Thank you.

hibernate onetomany annotation fetch = FetchType.LAZY didn't work

I have three tables A,B and C. Table B has a foreign key a_id reference to table A, Table B has a foreign key a_id reference to table A. And my hibernate entity files are as following:
A.java
#Entity
#Table(name = "A")
public class A {
private long id;
private String contentA;
private List<B> bList;
private List<C> cList;
#OneToMany(fetch = FetchType.EAGER , mappedBy = "b")
public List<B> getbList() {
return bList;
}
public void setbList(List<B> bList) {
this.bList = bList;
}
#OneToMany(fetch = FetchType.EAGER , mappedBy = "b")
public List<C> getcList() {
return cList;
}
public void setcList(List<C> cList) {
this.cList = cList;
}
#Id
#Column(name = "id", nullable = false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
#Basic
#Column(name = "content_a", nullable = false, length = 1000)
public String getContentA() {
return contentA;
}
public void setContentA(String contentA) {
this.contentA = contentA;
}
}
B.java
#Entity
#Table(name = "B")
public class B {
private long id;
private String contentB;
private A a;
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "a_id", nullable = false)
public A getA() {
return a;
}
public void setA(A a) {
this.a = a;
}
#Id
#Column(name = "id", nullable = false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
#Basic
#Column(name = "content_b", nullable = false, length = 1000)
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 String contentC;
private A a;
#ManyToOne(fetch = FetchType.EAGER)
#JoinColumn(name = "a_id", nullable = false)
public A getA() {
return a;
}
public void setA(A a) {
this.a = a;
}
#Id
#Column(name = "id", nullable = false)
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
#Basic
#Column(name = "content_c", nullable = false, length = 1000)
public String getContentC() {
return contentC;
}
public void setContentC(String contentC) {
this.contentC = 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?

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.

Jpa + Spring Data : cascading of a collection with compound key

I'm currently working on a small shop application for my School.
I have 2 objects I want to save :

}
public void setMailingAddress(MailingAddress mailingAddressByShippingAdrId) {
this.mailingAddress = mailingAddressByShippingAdrId;
}
#ManyToOne(fetch = FetchType.LAZY)
#JoinColumn(name = "USER_ID", referencedColumnName = "LOGIN")
public User getUser() {
return user;
}
public void setUser(User userByUserId) {
this.user = userByUserId;
}
#OneToMany(mappedBy = "order", fetch = FetchType.EAGER, cascade = CascadeType.ALL)
public Collection<OrderLine> getOrderLines() {

}
public void setOrderLines(Collection<OrderLine> orderLinesesById) {
this.orderLines = orderLinesesById;
}
}
OrderLine.java

}
An order contains a collection of order lines.
I'm trying to save the order + the order lines in one call to OrderRepository.
But when I do that, I get the error
org.hibernate.PropertyAccessException: Null value was assigned to a property of primitive type setter of edu.flst.bookstore.domaine.bo.OrderLinesPK.orderId
which is pretty logic (I know the Id of the order is unknow at this stage, because the primary key of order is auto-incremented (I use MySQL)).
I don't know how to make this work with one call to orderService (without saving orderLines with orderLinesRepository first). Is it even possible ?
Regards

An Order can contain many Books and a Book can appear in many Order(s). So the many-to-many relation is your OrderLine object essentially. I would set an id (autogenerated) and two many-to-one relations in OrderLine. Then you discard the OrderLinesPK class, you save the Order, Book and OrderLine objects in this order in the same transaction.In this way, your model is simpler and you only need to save an extra id (with no physical meaning) in the database (the id of the OrderLine object)

persisting a many to many relationship using hibernate and seam

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:

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.
