I want to query all instance of the entity Translation, which has reference to the entity Text. But, despite marking the Entity class with Serializable, hibernate complains. Why is that?
FYI I added Serializable to all of my Entity classes. The backing bean is @RequestScoped and annotated with @Named (CDI).
package com.doe.webapp.model.general.i18n;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToOne;
import javax.validation.constraints.NotNull;
import org.hibernate.validator.constraints.NotBlank;
import com.doe.webapp.model.RootEntity;
@Entity
public class Translation extends RootEntity implements Serializable {
public Translation(){
}
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
/**
* a text may have multiple translations.
*/
@ManyToOne
@JoinColumn(name = "textId")
private Text textUnit;
@OneToOne
@JoinColumn(name="localeId")
private Locale locale;
@Column
@NotNull
@NotBlank
private String translation;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public Text getTextUnit() {
return textUnit;
}
public void setTextUnit(Text textUnit) {
this.textUnit = textUnit;
}
public Locale getLocale() {
return locale;
}
public void setLocale(Locale locale) {
this.locale = locale;
}
public String getTranslation() {
return translation;
}
public void setTranslation(String translation) {
this.translation = translation;
}
}
I query this entity like this:
public List<Translation> getTranslations(Long id) {
List<Translation> translations = new LinkedList<Translation>();
CriteriaBuilder critBuilder = em.getCriteriaBuilder();
CriteriaQuery<Translation> criteriaQuery = critBuilder.createQuery(Translation.class);
Root<Translation> translation = criteriaQuery.from(Translation.class);
criteriaQuery.select(translation);
criteriaQuery.where(critBuilder.equal(translation.get(Translation_.id), id));
TypedQuery<Translation> typedQuery = em.createQuery(criteriaQuery);
translations = typedQuery.getResultList();
return translations;
}
And the error on invocation of this method is:

Does anybody have a clue why hibernate still complains?
Thanks heaps!
I Divide&Conquered by simply cutting each relationship and retried. It turned out to be a wrong relationship type definition for Locale. I removed the wrongly declared @JoinColumn defintions and changed it to a m-to-1 relationship.
@ManyToOne
private Locale locale;
Nothing more to do than that. I hope this helps another stackoverflower.
