Martin, are you using the simple mapping (w/o AJ) or the advanced AspectJ mapping?
I assume the simple mapping: There are several ways of persisting a RelationshipEntity() * (template or repository).createRelationshipBetween() * (template or repository).save(new Role(movie, actor, rolenName)); * node-entity with @Fetch @RelatedToVia Set<Role> roles=new HashSet<Role>(); actor = (template or repository).findOne(actorId); // or other loading mechanisms actor.roles.add(new Role(movie, actor, rolenName)); (template or repository).save(actor) if you are not using the first approach, you have to provide a RelationshipType for Role * as part of the @RelationshipEntity(type="TYPE") annotation * or as a @RelationshipType String type; field We can also have a skype call if you want to clarify things.
