Hello,

I work with spring MVC 3.2.6, Hibernate 4, Eclipse Juno.

I have the following entities PlantillaEncuesta and PlantillaEncuestaPK

PlantillaEncuesta

Code:
/**
* The persistent class for the PLANTILLA_ENCUESTA database table.
*
*/
@Entity
@Table(name="PLANTILLA_ENCUESTA")
public class PlantillaEncuesta implements Serializable {
   private static final long serialVersionUID = 1L;

   @EmbeddedId
   private PlantillaEncuestaPK id;
   
   

   @Lob
   private String contenido;

   //bi-directional many-to-one association to EncuestaSem
   @ManyToOne
   @JoinColumns({
      @JoinColumn(name="ID_ENCUESTA_SEM", referencedColumnName="ENCUESTA_SEM_ID"),
      @JoinColumn(name="SURVEY_ID", referencedColumnName="SURVEY_ID")
      })
   

   private EncuestaSem encuestaSem;

   public PlantillaEncuesta() {
   }

   public PlantillaEncuestaPK getId() {
      return this.id;
   }

   public void setId(PlantillaEncuestaPK id) {
      this.id = id;
   }

   public String getContenido() {
      return this.contenido;
   }

   public void setContenido(String contenido) {
      this.contenido = contenido;
   }

   public EncuestaSem getEncuestaSem() {
      return this.encuestaSem;
   }

   public void setEncuestaSem(EncuestaSem encuestaSem) {
      this.encuestaSem = encuestaSem;
   }

}


PlantillaEncuestaPK

Code:
/**
* The primary key class for the PLANTILLA_ENCUESTA database table.
*
*/
@Embeddable
public class PlantillaEncuestaPK implements Serializable {
   //default serial version id, required for serializable classes.
   private static final long serialVersionUID = 1L;

   @Column(name="ID_ENCUESTA_SEM")
   private long idEncuestaSem;

   @Column(name="PLANTILLA_ENCUESTA_ID")
   private long plantillaEncuestaId;

   @Column(name="SURVEY_ID")
   private long surveyId;

   public PlantillaEncuestaPK() {
   }
   public long getIdEncuestaSem() {
      return this.idEncuestaSem;
   }
   public void setIdEncuestaSem(long idEncuestaSem) {
      this.idEncuestaSem = idEncuestaSem;
   }
   public long getPlantillaEncuestaId() {
      return this.plantillaEncuestaId;
   }
   public void setPlantillaEncuestaId(long plantillaEncuestaId) {
      this.plantillaEncuestaId = plantillaEncuestaId;
   }
   public long getSurveyId() {
      return this.surveyId;
   }
   public void setSurveyId(long surveyId) {
      this.surveyId = surveyId;
   }

   public boolean equals(Object other) {
      if (this == other) {
         return true;
      }
      if (!(other instanceof PlantillaEncuestaPK)) {
         return false;
      }
      PlantillaEncuestaPK castOther = (PlantillaEncuestaPK)other;
      return
         (this.idEncuestaSem == castOther.idEncuestaSem)
         && (this.plantillaEncuestaId == castOther.plantillaEncuestaId)
         && (this.surveyId == castOther.surveyId);
   }

   public int hashCode() {
      final int prime = 31;
      int hash = 17;
      hash = hash * prime + ((int) (this.idEncuestaSem ^ (this.idEncuestaSem >>> 32)));
      hash = hash * prime + ((int) (this.plantillaEncuestaId ^ (this.plantillaEncuestaId >>> 32)));
      hash = hash * prime + ((int) (this.surveyId ^ (this.surveyId >>> 32)));
      
      return hash;
   }
}


When I deploy my project, I get the following error

Code:

Where do I have to add insert="false" update="false"?

Thanks in advance

The error message is pretty clear, so you should change the mapping to this:

Code:
@ManyToOne
@JoinColumns({
  @JoinColumn(name="ID_ENCUESTA_SEM", referencedColumnName="ENCUESTA_SEM_ID", insert=false update=false),
  @JoinColumn(name="SURVEY_ID", referencedColumnName="SURVEY_ID", insert=false update=false)
})
