Full error message:
org.hibernate.PropertyValueException:
not-null property references a null or
transient value:
Entities.Transaction1.transactionDateorg.hibernate.PropertyValueException:
not-null property references a null or
transient value:
Entities.Transaction1.transactionDate
I debugged it and it seemed like there is a value property of not null is null, which i dont seem to understand this error message. I thought I dont need to persist transactionID, as it is set to autoincrement, and transactionDate to timestamp oncurrentupdate. Can anyone please kindly help to fix?

The transactionDate field has been marked with #Basic(optional = false). Ensure that the value for this field is not null while persisting the Transaction.
If the transactionData can be genuinely null (I guess not), you can remove the optional option from #Basic.

could not resolve property hibernate with native SQL query

I have an issue with creating a query with hibernate template. I've take a look at many tutorial and i create my query that look like this
List fids = getHibernateTemplate().execute(new HibernateCallback<List>() {
#Override
public List doInHibernate(Session session) throws HibernateException {
Query query = session.createQuery(
"SELECT DISTINCT m.fournisseurs_id FROM Medicamentfournisseur as m, Composantcommandeclient as c WHERE c.medicamentsFournisseurs_id= m.id AND c.commandeclients_id = :id"
);
query.setParameter(":id", id);
return query.list();
}
});
I try query in SQL console and it works but in my apps i got this error :
error :could not resolve property: fournisseurs_id of: com.project.caritas.model.Medicamentfournisseur [SELECT DISTINCT m.fournisseurs_id FROM com.project.caritas.model.Medicamentfournisseur as m, com.project.caritas.model.Composantcommandeclient as c WHERE c.medicamentsFournisseurs_id= m.id AND c.commandeclients_id = :id]; nested exception is org.hibernate.QueryException: could not resolve property: fournisseurs_id of: com.project.caritas.model.Medicamentfournisseur [SELECT DISTINCT m.fournisseurs_id FROM com.project.caritas.model.Medicamentfournisseur as m, com.project.caritas.model.Composantcommandeclient as c WHERE c.medicamentsFournisseurs_id= m.id AND c.commandeclients_id = :id]

}
If someone can explain me how to solve this.
PS: Sorry for my bad english
you should use:
SELECT DISTINCT m.fournisseurs FROM Medicamentfournisseur as m ...
Because this is not a sql actually, it is a HQL of hibernate like sql. You should use the member name in java but not table column name.

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"),

public class Kategoriler implements Serializable {

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!
