update:

domainecompetence.java

@entity @table(name = "domainecompetence", catalog = "test", schema = "") @xmlrootelement @namedqueries({ @namedquery(name = "domainecompetence.findall", query = "select d domainecompetence d"), @namedquery(name = "domainecompetence.findbydomaine", query = "select d domainecompetence d d.domaine = :domaine")}) public class domainecompetence implements serializable { private static final long serialversionuid = 1l; @id @basic(optional = false) @notnull @size(min = 1, max = 200) @column(name = "domaine", nullable = false, length = 200) private string domaine; @onetomany(cascade = cascadetype.persist, mappedby = "domaine") //and have tried cascadtype.all private collection<personne> personnecollection; //getters , setters 

}

regarding second error:

you try persist entity (personne) has entity (domaincompetence) attached through relation in entity class. did not set relation cascade=persist or cascade=all. entitymanager doesn't know entity. here example how cascade attribute can set:

@onetomany(cascade = cascadetype.all, mappedby = "...") private list<personne> personnelist; 

look domaincompetence entity class , change accordingly. hope helps bit further.
