i know that the problem i get is because of this line but i don't know what to do to fix it

SalaireId id = new SalaireId(e.getSalaire().getPersonnel().getCin(),e.getSalaire().getMois().getMois());

This is an Hibernate problem. The entity has fields declared to be lazy loaded but the entity is not attached to a valid Hibernate Session to fire the proxies to retrieve the data lazily. From the stacktrace, I cannot be sure if this error is thrown by e.getSalaire().getPersonnel().getCin() or .getSalaire().getMois().getMois() (or maybe both).

I don't know how you configured the session management, probably Spring is handling it. To solve this, you should re attach the entity to a valid Hibernate Session. You can do this by using HibernateTemplate#refresh method from the Spring Hibernate integration classes.

i don't know how to use hibernate template, can you explain more how i could do this. For this question i solved it using getEmission().getSalaire().getPersonnel().getCin() but i get the same problem again in another bean and it don't get fixed even if i do that.@Luiggi Mendoza
Please post how yiu define you dao classes.
