I'm using some JavaFX properties in my app:

#NamedQuery(name = "Klanten.findAll", query = "select k from Klanten k")
})
public class Klant implements Serializable {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
private int klantId;
#Transient
private final SimpleStringProperty naam = new SimpleStringProperty();
//private String naam;
//private String straat;
#Transient
private final SimpleStringProperty straat = new SimpleStringProperty();
private String telefoon;
private String huisnummer;
private String gsm;
private String woonplaats;
private String email;
private String postcode;
#OneToMany(mappedBy = "Klant", cascade = CascadeType.REMOVE)
private List<Raam> ramen;
public Klant() {
}
public Klant(String naam) {
this.naam.set(naam);
}
#Override
public String toString() {
return this.naam.get();
}
#Access(AccessType.PROPERTY)
#Column(name="naam")
public String getNaam() {
return this.naam.get();
}
public void setNaam(String naam){
this.naam.set(naam);
}
public List<Raam> getRamen() {
return this.ramen;
}
#Id
public int getKlantId() {

public void setKlantId(int klantId) {
this.klantId = klantId;
}
#Access(AccessType.PROPERTY)

public String getStraat() {
return straat.get();
}
public void setStraat(String straat) {
this.straat.set(straat);
}
public String getTelefoon() {
return telefoon;
}
public void setTelefoon(String telefoon) {
this.telefoon = telefoon;
}
public String getHuisnummer() {

}
public void setHuisnummer(String huisnummer) {
this.huisnummer = huisnummer;
}
public String getGsm() {
return gsm;
}
public void setGsm(String gsm) {
this.gsm = gsm;
}
public String getWoonplaats() {
return woonplaats;
}
public void setWoonplaats(String woonplaats) {
this.woonplaats = woonplaats;
}
public String getEmail() {

}
public void setPostcode(String postcode) {

}
public StringProperty naamProperty() {
return naam;
}
public StringProperty straatProperty() {
return straat;
}
}
However when I let JPA generate my database, the column "naam" and "straat" aren't generated. I get no error. How can I resolve this?
I tried all the things listed here:
Possible solution 1
Possible solution 2
These didn't work.
You can try to use regular properties and then have another get method which returns a new SimpleStringProperty, i.e.:
public StringProperty naamProperty() {
return new SimpleStringProperty(naam);
}
public StringProperty straatProperty() {
return new SimpleStringProperty(straat);
}

options.setQuestion(question);
options.setQuestionOptionNumber(option.getQuestionOptionNumber());
optionList.add(options);

You are creating only one object of QuestionOption
QuestionOption options = new QuestionOption();
Create this object inside for each.
i have a rellationship between 2 classes Document and Medecin

public Date getDateVisite() {

public void setDateVisite(Date dateVisite) {

and the medecin entity is
#Entity
public class Medecin implements Serializable {

private long id;
private String nom;
private String secteur;
private int telephone;
private int specialite;

}
public int getSpecialite() {

}

}
}
the problem is that after i generate the database i want if i delete the document record from the database i want the medecin record will be deleted also but in my case if i delete the document record the medecin record dont be deleted
Based on your configuration, Hibernate will generate Document table with foreign key pointing to Medicine table.
To achieve your requirement, it should be like:
public class Document {
#OneToOne(mappedBy = "document", cascade = CascadeType.REMOVE)
private Medicine medicine;
}
public class Medicine {
#OneToOne
private Document document;
}
Updated
public void delete(int id){
Document document = entityManager.find(Document.class, id);
entityManager.remove(document);
entityManager.flush();
}
I have three entities, Trader, Portfolio and Member. Each Trader has a Portfolio and a Portfolio can have many Members. I have set up the following relationships. I'm not sure how to use the Jointable that is created, i.e. Portfolio_PORTFOLIOID and members_MEMBERID. Obviously I'd like to associate each portfolid with member id's, however I'm not sure how to go about this. How is the jointable data persisted?

i'm starting with Rest and don't have no idea how to implement it properly. I got an exercise: i must implement a Rest-Client with the RestClient-API from javax.ws.rs standard library and i tried by using the code below, but i'm getting a null pointer exception. But the resource are there and when i try directly from the browser (http://localhost:8080/sep/rest/customers/112). Now my question how can i do it properly. Some constraints, i must use XML (not JSON) for the Data-support.
Hier my client-code:
public Response createCustomer(Customer customer){
log.info("Starting: Rest Create a Customer with Name: " + Customer.class.getName());
this.customerWebTarget = this.client.target(URL);
Response response = this.customerWebTarget.request().
buildPost(Entity.entity(customer, MediaType.APPLICATION_XML)).invoke();
log.info("Ending: Rest Create a Customer with Name: " + response.getEntity().getClass().getName());
return response;
}
CustomerResource-Code:
#Path("customers")
public class CustomerResource implements IAllowedMethods<Customer> {
private static final long serialVersionUID = -6367055402693237329L;
private Logger logger = Logger.getLogger(CustomerResource.class.getName());
#Inject

logger.info("create of instance " + this.getClass().getName());
}
#Override
#GET
#Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
public Response get() {
List<Customer> list = service.loadAll(Customer.FINDALL, Customer.class);
if (list != null && !list.isEmpty()) {
ResponseCustomerList responseList = new ResponseCustomerList();
responseList.setList(list);
return Response.ok(responseList).build();

Instead of response.getEntity(), use response.readEntity(String.class) to get the data as a String. If you want to deserialize it to a POJO, then just pass that class to the readEntity.
Also you should make sure to check the status code (response.getStatus()) to make sure it's a success status.
