Vaadin JPAContainer: ManytoOne relation with EmbeddedID

Vaadin JPAContainer: ManytoOne relation with EmbeddedID - java

There are questions similar but not quite. In those cases (and in the JPAContainer examples) the Entity part of the ManyToOne relationship has a single key. In my case it is an embedded id.
My code is based on the Address Book example.
Here are the three entities:
#Entity
#Table(name = "tutorial")
#XmlRootElement
#NamedQueries({
#NamedQuery(name = "Tutorial.findAll", query = "SELECT t FROM Tutorial t"),
#NamedQuery(name = "Tutorial.findById", query = "SELECT t FROM Tutorial t WHERE t.tutorialPK.id = :id"),
#NamedQuery(name = "Tutorial.findByTutorialTypeId", query = "SELECT t FROM Tutorial t WHERE t.tutorialPK.tutorialTypeId = :tutorialTypeId"),
#NamedQuery(name = "Tutorial.findByMessage", query = "SELECT t FROM Tutorial t WHERE t.message = :message")})
public class Tutorial implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
protected TutorialPK tutorialPK;
#Basic(optional = false)
#NotNull
#Size(min = 1, max = 245)
#Column(name = "message")
private String message;
#JoinColumn(name = "tutorial_type_id", referencedColumnName = "id", insertable = false, updatable = false)
#ManyToOne(optional = false)
private TutorialType tutorialType;
public Tutorial() {
}
public Tutorial(TutorialPK tutorialPK) {
this.tutorialPK = tutorialPK;
}
public Tutorial(TutorialPK tutorialPK, String message) {
this.tutorialPK = tutorialPK;
this.message = message;
}
public Tutorial(int id, int tutorialTypeId) {
this.tutorialPK = new TutorialPK(id, tutorialTypeId);
}
public TutorialPK getTutorialPK() {
return tutorialPK;
}
public void setTutorialPK(TutorialPK tutorialPK) {
this.tutorialPK = tutorialPK;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public TutorialType getTutorialType() {
return tutorialType;
}
public void setTutorialType(TutorialType tutorialType) {
this.tutorialType = tutorialType;
}
#Override
public int hashCode() {
int hash = 0;
hash += (tutorialPK != null ? tutorialPK.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 Tutorial)) {
return false;
}
Tutorial other = (Tutorial) object;
if ((this.tutorialPK == null && other.tutorialPK != null) || (this.tutorialPK != null && !this.tutorialPK.equals(other.tutorialPK))) {
return false;
}
return true;
}
#Override
public String toString() {
return "games.jwrestling.server.game.db.persistence.Tutorial[ tutorialPK=" + tutorialPK + " ]";
}
}
And the EmbeddedId class:
#Embeddable
public class TutorialPK implements Serializable {
#Basic(optional = false)
#NotNull
#Column(name = "id")
private int id;
#Basic(optional = false)
#NotNull
#Column(name = "tutorial_type_id")
private int tutorialTypeId;
public TutorialPK() {
}
public TutorialPK(int id, int tutorialTypeId) {
this.id = id;
this.tutorialTypeId = tutorialTypeId;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public int getTutorialTypeId() {
return tutorialTypeId;
}
public void setTutorialTypeId(int tutorialTypeId) {
this.tutorialTypeId = tutorialTypeId;
}
#Override
public int hashCode() {
int hash = 0;
hash += (int) id;
hash += (int) tutorialTypeId;
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 TutorialPK)) {
return false;
}
TutorialPK other = (TutorialPK) object;
if (this.id != other.id) {
return false;
}
if (this.tutorialTypeId != other.tutorialTypeId) {
return false;
}
return true;
}
#Override
public String toString() {
return "games.jwrestling.server.game.db.persistence.TutorialPK[ id=" + id + ", tutorialTypeId=" + tutorialTypeId + " ]";
}
}
And another one:

}
return true;
}
#Override

}
}
I got the form set up and it works fine when I edit the items, but creating I get errors because the TutorialPK is null:

}
public Item getSavedItem() {
return savedItem;
}
}
public interface EditorSavedListener extends Serializable {

And another one:

private void setTutorialType(TutorialType type) {
this.type.setValue(type != null ? type.getId() : null);
}
#Override
public Class<? extends TutorialType> getType() {
return TutorialType.class;
}
}
Any idea on how to populate this field?
Update:
Error after using #MapsId
Exception [EclipseLink-46] (Eclipse Persistence Services - 2.6.2.v20151217-774c696): org.eclipse.persistence.exceptions.DescriptorException
Exception Description: There should be one non-read-only mapping defined for the primary key field [tutorial.tutorial_type_id].
Descriptor: RelationalDescriptor(games.jwrestling.server.game.db.persistence.Tutorial --> [DatabaseTable(tutorial)])

Two ways. If using JPA 1.0, you will need to pull the value from the referenced tutorialType and manually add it to the tutorial.tutorialPK.tutorialTypeId. You didn't include the tutorialType entity, but if it's ID value is generated, you may need to persist it and flush before the value is assigned.
If using JPA 2.0, you can specify the #MapsId annotation in your entity, allowing JPA to set the tuturial.tutorialPK.tutorialTypeId value from the tutorial.tutorialType reference for you:
public class Tutorial implements Serializable {
private static final long serialVersionUID = 1L;
#EmbeddedId
protected TutorialPK tutorialPK;
#Basic(optional = false)
#NotNull
#Size(min = 1, max = 245)
#Column(name = "message")
private String message;
#MapsId("tutorialTypeId")
#ManyToOne(optional = false)
private TutorialType tutorialType;
You will not be able to change the TutorialType associated to a tutorial once it is created though - the only option is to delete the existing one and create a new one with the new values.

JPQL Subquery - Exception this expression has an invalid table in this context

I have a (inneficient, but working) T-SQL (sub)query
SELECT * FROM DIAGE.ade.UorPos WHERE Prefixo IN
(SELECT PrefixoJurisdicionada FROM DIAGE.ade.Jurisdicionadas WHERE Prefixo =
(SELECT Prefixo FROM DIAGE.ade.Jurisdicionadas WHERE PrefixoJurisdicionada = 8922))
AND CodComissao IN (4345, 4346, 4347)
which I've build the correspondent JPQL
SELECT u FROM UorPos u WHERE u.prefixo IN

(SELECT j.prefixo FROM Jurisdicionadas j WHERE j.prefixoJurisdicionada = :prefixo))

Despite compiling, when running launches the Exception:

I've made some research and, in my understanding, my JPQL query is ok.
Can anyone help me to resolve this?
Some links I've researched:

How do I do a JPQL SubQuery?

Using IN with a subquery
I'm using EclipseLink version 2.5.2 (integrated with Netbeans 8.0.2), Glassfish 4.1, Java 1.7.0_71.

Thanks in advance.

After the great hint posted by htshame, I've researched about Eclipselink Native SQL Queries and workarounded the problem as below:
public List<UorPos> findUorPosExecutivosByPrefixo(Prefixos prefixo) {
return (List<UorPos>) getEntityManager().createNativeQuery("SELECT * FROM DIAGE.ade.UorPos WHERE prefixo IN (SELECT prefixoJurisdicionada FROM DIAGE.ade.Jurisdicionadas WHERE prefixo = (SELECT prefixo FROM DIAGE.ade.Jurisdicionadas WHERE prefixoJurisdicionada = ?)) AND codComissao IN (4345, 4346, 4347) ORDER BY nome, matricula", UorPos.class).setParameter(1, prefixo.getPrefixo()).getResultList();
}
But, if someone could resolve the JPQL named query issue, it will be better.

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);
}
}

Wrong SQL update query generated on merge

When using EntityManager's merge method on WebSphere Application Server 7 with MS SQL Server 2008 to update entity in database, wrong SQL query being generated (no update parameters after SET keyword (see stacktrace below)).
Most likely this issue occurs when I'm trying to merge entity with no changes regarding DB, but this aint gettin me closer to solution.
Does anybody has a solution/workaround for this?

I think you use the unstable 1.2.4-SNAPSHOT version of OpenJPA. I would downgrade it to 1.2.3 and see if the problem still occurs.
On the other side, I suppose the error occurs (please test that) only if OpenJPA does not have any fields to update. In this case, I would simply surround the code with an try-catch block, and ignore the error (you asked for a workaround).

JPA : Count with predicate on MapJoin

I have a problem with a criteria count query with a MapJoin !
In fact it doesn't work !
Here is my code :
public long countItems(final String title, final String url) {
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<CmsItem> query = builder.createQuery(entityClass);
Root<CmsItem> page = query.from(entityClass);
query.select(page);
MapJoin<Map<Lang, CmsItemLang>, Lang, CmsItemLang> mapJoin = page
.joinMap("cmsItemLang");
List<Predicate> predicateList = new ArrayList<Predicate>();
Predicate titlePredicate, urlPredicate;
if ((title != null) && (!(title.isEmpty()))) {
titlePredicate = builder.like(
builder.upper(mapJoin.value().<String> get("metaTitle")),
"%" + title.toUpperCase() + "%");
predicateList.add(titlePredicate);
}
if ((url != null) && (!(url.isEmpty()))) {
urlPredicate = builder.like(
builder.upper(mapJoin.value().<String> get("linkRewrite")),
"%" + url.toUpperCase() + "%");
predicateList.add(urlPredicate);
}
Predicate[] predicates = new Predicate[predicateList.size()];
predicateList.toArray(predicates);
query.where(predicates).distinct(true);
CriteriaQuery<Long> cq = builder.createQuery(Long.class);
cq.select(builder.count(cq.from(entityClass)));
entityManager.createQuery(cq);
cq.where(predicates);
Long count = entityManager.createQuery(cq).getSingleResult();
return count;
}
and I have this error when I call the method url param or title param is not null :
org.hibernate.QueryException: could not resolve property: linkRewrite of: com.demkocompany.models.CmsItem [select count(*) from com.demkocompany.models.CmsItem as generatedAlias0 where upper(generatedAlias0.linkRewrite) like :param0]

I don't understand why I have this error when I try to do that ...
Because without the count (in an other method to find the items) it works well ...
But to count all the result of the search ...the request is false ...
Is someone can help me to correct this ?
Thanks a lot

That error is likely due to the class com.demkocompany.models.CmsItem does not have linkRewrite property. Double check you do have it and the accessibility has to be public (I think)
public String getLinkRewrite() {
// ...
}
public void setLinkRewrite(String linkRewrite) {
// ...
}

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!
