How can I fix an ORMException ?

[13年前 に Carole Béatrice DEMGNE KAMDEM によって更新されました。]

Hi all,

I write an service.xml like this

<!--?xml version="1.0" encoding="UTF-8"?-->


<service-builder package-path="com.mypackage">
    <namespace>ns</namespace>
    <entity name="personnes" local-service="true" remote-service="false">
        <!-- PK fields -->
        <column name="idPersonne" type="Integer" primary="true" id-type="class" id-param="com.liferay.counter.service.persistence.IDGenerator" />
        <!-- Other fields -->
        <column name="nom" type="String" />
        <column name="prenom" type="String" />
    </entity>
</service-builder>

I run ant task build-service, when I deploy I see the table "ns_personnes" in mysql database
But when I add a row in the table ns_personnes with code (JspPortlet.java)

personnes personne = personnesLocalServiceUtil.addInvoices("nom", "prenom");

I get this error on tomcat's log

com.liferay.portal.SystemException:com.liferay.portal.kernel.dao.orm.ORMException :
