Hi List.

I've got a error on a jsp. I can't retrieve a oneToMany collection. GroupeNote have a list of ItemNote. I've just modified the generated form of GroupeNote (from groupeNoteform.jsp) and had a list of ItemNote (from itemNotes.html) lazyLoadingFilter is activated in web.xml.

my model code : ----------------------------- @Entity public class GroupeNote implements java.io.Serializable { ... @OneToMany @JoinColumn(name="GROUPENOTE_ID") public Set<ItemNote> getNotes() { return notes; } ... }

@Entity public class ItemNote implements java.io.Serializable { ... @ManyToOne @JoinColumn(name="GROUPENOTE_ID", insertable=false, updatable=false) public GroupeNote getGroupeNote() { return groupeNote; } ... } -----------------------------

the error : ----------------------------- org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: model.GroupeNote.notes, no session or session was closed at
