How do you update an entity in jpa using the put method ?
I am updating using the following JSON:
{
"acceptedGender":"both",
"price":123123.00,
"type":"apartment",
"vacantNum":13,
"hadID":4
}
I used the put method below for updating is it correct?
Can someone pls help me
Here is my code:

try{
em.getTransaction().begin();
em.persist(entity);
em.getTransaction().commit();
}finally{
em.close();
}
}**
#PUT

update = entity;
em.persist(update);
em.getTransaction().commit();
}finally{
em.close();
}
}

Java Persistence: Cannot add or update a child row: a foreign key constraint fails

Basically I'm implementing a PDS (Personal Data Sheet) so I have tables such as Client (employee), Personalinfo, Otherinfo.
Client table structure:
idClients, name, institute, username, password, usertype
Personalinfo table structure:
idPersonalInfo, agencyno, bloodtype, status, citizenship, address, idClients
I can add client successfully but when I'm trying to add/update personalinfo, I get
MySQLIntegrityConstraintViolationException: Cannot add or update a child row: a foreign key constraint fails
In personalinfo class I have this line also:
#JoinColumn(name = "idClients", referencedColumnName = "idClients", insertable = false, updatable = false)
In Clients class I also included:
#OneToOne(cascade = CascadeType.ALL, mappedBy = "clients")
private Personalinfo personalinfo;
But I can't figure out why I'm getting constraint violations.
Error Code: 1452
Call: INSERT INTO personalinfo (...) VALUES (...)
bind => [7parameters bound]
Query: InsertObjectQuery(com.profiling.database.Personalinfo[ idPersonalInfo=null ])
EDIT:
if (personal != null) {
.....
personal.setClients(client);
personal.setIdPersonalInfo(client.getIdClients());
EntityManager em = emanager.getEntityManager();
em.getTransaction().begin();
em.persist(personal);
em.getTransaction().commit();
JOptionPane.showMessageDialog(rootPane, "Personal Info Updated Successfully");
} else {
personal = new Personalinfo();
....
personal.setClients(client);
client.setPersonalinfo(personal);
EntityManager em = emanager.getEntityManager();
em.getTransaction().begin();
em.persist(personal);
em.getTransaction().commit();
JOptionPane.showMessageDialog(rootPane, "New Personal Info Save");

Since findAll is not static, you need to create an instance of your PropertyFaçade. You can't just call PropertyFacade.findAll(). In spring, you would get this instance from the ApplicationContext, not sure how it is being created in ejb.
Note: mind the naming convention in java: the variables start with lowercase letter and the classes start with an uppercase letter. So, you should change PropertyList to propertyList.

In your servlet, do following:
#EJB
PropertyFacade propertyFacade;
#Override
public void init() throws ServletException {
List<Property> PropertyList= propertyFacade.findAll();
getServletContext().setAttribute("property", PropertyList);
}
And add #Stateless annotation in your PropertyFacade.class
#Stateless
public class PropertyFacade extends AbstractFacade<Property> {
#PersistenceContext(unitName = "testRealPU")
private EntityManager em;
#Override
protected EntityManager getEntityManager() {
return em;
}
public PropertyFacade() {
super(Property.class);
}

Hibernate ManyToOne Mapping

I have a class named Urunler and another class named Kategoriler.
Urunler table has foreign key which is primary key of Kategoriler table.
A Kategoriler object can have multiple Urunler object.
I need to have ManyToOne mapping from Urunler class to Kategoriler class.
But I could not achieve it.
Error tells me that I have not set katid foreign key of Urunler table.
Here is my code:
#Entity
#Table(name = "urunler")
#XmlRootElement
#NamedQueries({
#NamedQuery(name = "Urunler.findAll", query = "SELECT u FROM Urunler u"),
#NamedQuery(name = "Urunler.findById", query = "SELECT u FROM Urunler u WHERE u.id = :id"),

return false;

#Override

And this Kategoriler class:

#NamedQuery(name = "Kategoriler.findById", query = "SELECT k FROM Kategoriler k WHERE k.id = :id"),

public class Kategoriler implements Serializable {
private static final long serialVersionUID = 1L;
#Id
#GeneratedValue
#Basic(optional = false)
#Column(name = "id")
private Integer id;
#Column(name = "ad")

private String aciklama;
public Kategoriler() {
}
public Kategoriler(Integer id) {
this.id = id;
}
public Integer getId() {
return id;

public void setId(Integer id) {
this.id = id;
}
public String getAd() {
return ad;
}
public void setAd(String ad) {

public String getAciklama() {

public void setAciklama(String aciklama) {

#Override

return hash;
}
#Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Kategoriler)) {

}
Kategoriler other = (Kategoriler) object;
if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
return false;
}
return true;
}
#Override
public String toString() {
return "HibClasses.Kategoriler[ id=" + id + " ]";
}
}
And this is where I call them:
btnDuzenle.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent ae) {
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
Urunler urunler = new Urunler();
Kategoriler kategoriler = new Kategoriler();
kategoriler.setAd("Gıda");
kategoriler.setAciklama("Yenir la bunlar");
urunler.setAd("Bisküvi");
urunler.setAciklama("Biskrem");
urunler.setAlis("4");
urunler.setSatis("5");
urunler.setKategori(kategoriler);
urunler.setStok("4");
session.save(urunler);
session.getTransaction().commit();
}
});

I found a solution.
I have changed
...
#ManyToOne(cascade = CascadeType.ALL)
private Kategoriler kategori;
public Kategoriler getKategori() {
return kategori;
}
...
to that:
...
#ManyToOne(cascade = CascadeType.ALL)
#JoinColumn(name = "katid")
private Kategoriler kategori;
public Kategoriler getKategori() {
return kategori;
}
...
AND
...
#Column(name = "katid")
private Integer katid;
public Integer getKatid() {
return katid;
}
...
to that:
...
#Column(name = "katid", insertable = false , updatable = false)
private Integer katid;
public Integer getKatid() {
return katid;
}
...

Kategoriler should have a list of mapped by Kategoriler objects with proper anotations:
#OneToMany(mappedBy="kategoriler",cascade=CascadeType.ALL)
private List<Urunler> employees = new ArrayList<Urunler >();

Persisting OneToMany relationship only persists first object in set?

Been messing around with Hibernate and PostgreSQL trying to get it to work as expected.
But for some reason when I try to persist an object with a #OneToMany relationship with more than one item in the set all but the first item seem to be ignored. I've tried this via local and remote interfaces but get the same results each time. No exceptions are thrown, it looks like hibernate just stops persisting after the first unit has been persisted.
Any help much appreciated this one has been eluding me for days now.
I'm using Hibernate 3.5 and PostgreSQL 8.4.4 with Glassfish v3. All the annotations in the source are from the package javax.persistence - had to remove imports because of the character limit.
The FacadeManager is simply a utility to take the hassle out of jndi lookups, it simplifies accessing remote facades.
Here is the test method
#Test
public void testOneToManyCascade() throws Exception {
/*
* Set up entities requred to perform the test
*/
UnitFacadeRemote unitfr = FacadeManager
.getFacade(UnitFacadeRemote.class);
UserFacadeRemote userfr = FacadeManager
.getFacade(UserFacadeRemote.class);
User user = new User("P", "P", "000000", true, new Date(), "ypy#ypy",
"wordof mout", "slacker", "password");
Address address = new Address("yo", "go", "YOKO", "4123");
address.setCountry(FacadeManager.getFacade(CountryFacadeRemote.class)
.find(2));
user.setAddress(address);
Unit unit1 = new Unit(1, "Test Unit1", new Date(), "DisService",
"MyNation");
Unit unit2 = new Unit(2, "Test Unit2", new Date(), "DisService",
"TheirNation");
Unit unit3 = new Unit(3, "Test Unit3", new Date(), "DisService",
"TheirNation");
// Check no game exists
assertThat(FacadeManager.getFacade(GameFacadeRemote.class).findAll()
.size(), is(0));
Game game = new Game("blabla", 3333, "A game!", true);
// Create game and return reference to persisted game instance
game = FacadeManager.getFacade(GameFacadeRemote.class).registerGame(
game);
unit1.setGame(game);
unit2.setGame(game);
unit3.setGame(game);
// Find a virtue
Virtue v = FacadeManager.getFacade(VirtueFacadeRemote.class).find(1);
unit1.setVirtue(v);
unit2.setVirtue(v);
unit3.setVirtue(v);
// check that none of the above exist already
assertThat(userfr.findAll().size(), is(0));
assertThat(unitfr.findAll().size(), is(0));
/*
* Try persisting the by cascading from the user
*/
Set<Unit> unitSet = new HashSet<Unit>();
unitSet.add(unit2);
unitSet.add(unit1);
unitSet.add(unit3);
user.setUnitSet(unitSet);
unit1.setUser(user);
unit2.setUser(user);
unit3.setUser(user);
// Persist
userfr.create(user);
/*
* The result of the preceding persist is that the game, user, address
* and one unit are persisted, in this case unit2 but it seems whichever
* unit is first added to unitSet is the one that is persisted.

You have a problem with the identity of the Unit objects. You're using in your code a HashSet which relies on equals and hashCode methods which are overridden in your code.
If you run the main method in the code below, you will see that after adding the Unit objects there is only one of them in the set (I reused your original code but I simplified it a bit):
import java.util.Date;
import java.util.HashSet;
import java.util.Set;
public class Unit {
private Integer id;
private Integer unitId;
private String name;
private Date registrationDate;
private String service;
private String nation;
public Unit() {
}
public Unit(Integer id) {
this.id = id;
}
public Unit(Integer unitId, String name, Date registrationDate, String service, String nation) {
this.unitId = unitId;
this.name = name;
this.registrationDate = registrationDate;
this.service = service;
this.nation = nation;
}
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public Integer getUnitId() {
return unitId;
}
public void setUnitId(Integer unitId) {
this.unitId = unitId;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public Date getRegistrationDate() {
return registrationDate;
}
public void setRegistrationDate(Date registrationDate) {
this.registrationDate = registrationDate;
}
public String getService() {
return service;
}
public void setService(String service) {
this.service = service;
}
public String getNation() {
return nation;
}
public void setNation(String nation) {
this.nation = nation;
}
#Override
public int hashCode() {
int hash = 0;
hash += (id != null ? id.hashCode() : 0);
return hash;
}
#Override
public boolean equals(Object object) {
// TODO: Warning - this method won't work in the case the id fields are not set
if (!(object instanceof Unit)) {
return false;
}
Unit other = (Unit) object;
if ((this.id == null && other.id != null) || (this.id != null && !this.id.equals(other.id))) {
return false;
}
return true;
}
#Override
public String toString() {
return "com.game.database.entity.Unit[id=" + id + "]";
}
public static void main(String... args) {
Unit unit1 = new Unit(1, "Test Unit1", new Date(), "DisService", "MyNation");
Unit unit2 = new Unit(2, "Test Unit2", new Date(), "DisService", "TheirNation");
Unit unit3 = new Unit(3, "Test Unit3", new Date(), "DisService", "TheirNation");
Set unitSet = new HashSet();
unitSet.add(unit2);
unitSet.add(unit1);
unitSet.add(unit3);
System.out.println(unitSet.size());
}
If you comment out the equals() and hashCode() and run the code again you will see three objects in the set.
Your equals() method is based on the id property which is set by hibernate at time the object is being persisted and not at the time of adding to the set. It means that the Unit has always a null id and hashCode = 0 when added to the set. I recommend reading this article: http://community.jboss.org/wiki/EqualsandHashCode
Hope it helps!
