Persistence et Relation @ManyToMany

**Fr@ncky** · 08/02/2018, 19h08

Bonjour,

J'aimerais faire une relation many to many avec cette entité et ça me pose un problème lorsque j'essaye de deployer mon projet:

Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.6.1.v20150605-31e8258): org.eclipse.persistence.exceptions.EntityManagerSetupException Exception Description: Predeployment of PersistenceUnit [databasePU] failed. Internal Exception: Exception [EclipseLink-7174] (Eclipse Persistence Services - 2.6.1.v20150605-31e8258): org.eclipse.persistence.exceptions.ValidationException Exception Description: The getter method [method getEleves] on entity class [class ch.myapp.entity.bean.Cours] does not have a corresponding setter method defined.. Please see server.log for more details.
