Java spring bean erreur de configuration

dans mon application web développée avec GWT, Hibernate sna Printemps, je rencontre lors de la définition de la condition préalable de haricots dans le application-context.xml fichier.

J'ai cette erreur à l'exécution :

Error 500 Error creating bean with name 'schedulerFactory' defined in class path resource [application-context.xml]:
Cannot resolve reference to bean 'cronTrigger' while setting bean property 'triggers' with key [0];

nested exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'cronTrigger' defined in class path resource [application-context.xml]:
Cannot resolve reference to bean 'exampleJob1' while setting bean property 'jobDetail';

nested exception is org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'exampleJob1' defined in class path resource [application-context.xml]:
Initialization of bean failed;

nested exception is org.springframework.beans.TypeMismatchException:
Failed to convert property value of type [fr.web.utils.ExampleJob] to required type [java.lang.Class] for property 'jobClass';

nested exception is java.lang.IllegalArgumentException:
Cannot convert value of type [fr.web.utils.ExampleJob] to required type [java.lang.Class] for property 'jobClass':
PropertyEditor [org.springframework.beans.propertyeditors.ClassEditor] returned inappropriate value

Voici ma classe Java :

public class ExampleJob extends QuartzJobBean {
    private AbsenceDao absenceDao; 
    @Override
    protected void executeInternal(JobExecutionContext context)
    throws JobExecutionException {
        List untreatedDemands = new ArrayList();
        untreatedDemands = absenceDao.getDemandsAskedNotValidated();
    }
    public AbsenceDao getAbsenceDao() {
        return absenceDao;
    }
    public void setAbsenceDao(AbsenceDao absenceDao) {
        this.absenceDao = absenceDao;
    }
}

et voici mon application-context.xml :

    <!-- variables d'environnement - fichier properties -->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" id="placeholderconfig">
