JPA hibernate validator and richfaces a4J

[barcha]

Hi,

I'm trying to combine jpa 2.0 entity, hibernate validator 4.0 (with annotation) and richfaces validation messages.

My problem : javax ConstraintViolationException is raised instead of displaying error message in <rich:message/> tag. this happen when a left some field empty while this field contain a notEmpty annotation.

I know i can do it more simple with required attribute of the inputText but i think it's more easy and clear to handle this constraint directly from the entities.

Here is part of the serveur log.

Caused by: javax.validation.ConstraintViolationException: validation failed for classes [metier.entity.Vehicule] during persist time for groups [javax.validation.groups.Default, ]

     at org.hibernate.cfg.beanvalidation.BeanValidationEventListener.validate(BeanValidationEventListener.java:155) [:3.6.0.Final]

     at org.hibernate.cfg.beanvalidation.BeanValidationEventListener.onPreInsert(BeanValidationEventListener.java:94) [:3.6.0.Final]

     at org.hibernate.action.EntityIdentityInsertAction.preInsert(EntityIdentityInsertAction.java:160) [:3.6.0.Final]

Here is my entity :

@javax.persistence.Entity

@Table(name="VEHICULE", uniqueConstraints=@UniqueConstraint(columnNames="VEHICULE_IMMATRICULATION"))

public class Vehicule implements Entity, Serializable{

          /**

           *

           */

          private static final long serialVersionUID = 1L;

          @Id

          @GeneratedValue(strategy=GenerationType.AUTO)

          private int vehicule_id;

          @Column

          @NotEmpty(message="ce champ est obligatoire")

          private String vehicule_immatriculation;

          @Column

          @NotEmpty(message="ce champ est obligatoire")

          private String vehicule_marque;

and here is a part of my JSF managedBean :

public class VehiculeManagedBean implements Serializable{

          private static final long serialVersionUID = -2421214031111814582L;

          private static final Logger logger = Logger.getLogger(VehiculeManagedBean.class);

    private UIDataTable dataTable = new UIDataTable();

    private HtmlInputHidden dataItemId = new HtmlInputHidden();

     // handle all of persistency actions (CRUD) with DAO classes

    private IVehiculeService vehiculeService;

    private Vehicule vehiculeEntity;

And here is my xhtml part which should display error message when the fields are empty (it's inside a PopupPanel) :

                    <h:form>

                                                            <h:panelGrid id="editDiv" columns="4">

                                                                                <h:outputText value="marque" />

                                                                                <h:inputText

                                                                                          value="#{vehiculeManagedBean.vehiculeEntity.marque}"

                                                                                          id="marqueId">

                                                                                </h:inputText>

                                                                                <h:outputText value="*" />

                                                                                <rich:message for="marqueId" />

                                                                                <h:outputText value="immatriculation" />

                                                                                <h:inputText

                                                                                          value="#{vehiculeManagedBean.vehiculeEntity.immatriculation}"

                                                                                          id="immatriculationId">

                                                                                </h:inputText>

                                                                                <h:outputText value="*" />

                                                                                <rich:message for="immatriculationId" />

                                                                      <h:outputText value="description" />

                                                                      <h:inputTextarea

                                                                                value="#{vehiculeManagedBean.vehiculeEntity.description}" />

                                                            </h:panelGrid>

                                                                      <h:outputText value="(*) : Champs obligatoires" />

                                                                      <a4j:commandButton value="valider"

                                                                                action="#{vehiculeManagedBean.updateDataItem}"

                                                                                oncomplete="if (#{facesContext.maximumSeverity==null}) {#{rich:component('editDivPop')}.hide();}"

                                                                                render="dt" id="submitButton" execute="@form" />

                                                                      <a4j:commandButton value="annuler" id="cancelButton" render="dt"

                                                                                execute="editDivPop"

                                                                                onclick="#{rich:component('editDivPop')}.hide(); return false;" />

               </h:form>

I'm waiting for your suggestions, i can't find an issue how to validate my fields directly from my jpa entity.

Thank you so match in advance.

HI,

Please try with javax.validation annotations.

[barcha]

thank you for your reply

It's works now but not by using javax.validation annotations. It was because rich:message tag doesn't display error message in a rich:popuppanel. But rich:messages works fine.

Do you have any idea about that???

finally i found the solution but i don't know how. i use rich:message tag with for attribute inside a a4j:outputpanel to be rendered. i put my form inside rich:graphvalidator  with myEntity as the entity to be validated by the hibernate validator annotations.
