@Entity
    public class Person implements Serializable {
        private int id;
               ...........
        private Set<Languages> languages = new HashSet<Languages>();
           ...............
        @ManyToMany
        @JoinTable(name = "link_person_languages")
        public Set<Languages> getLanguages() {
           return languages;
        }
    }
    
    @Entity
    public class Languages implements Serializable {
        private int id;
        private String name;
        @Id
        @GeneratedValue
        public int getId() {
            return id;
        }
        @Column(nullable = false, length = 40, unique = true)
        public String getName() {
            return name;
        }

Lets say i have Languages Eng Germ, People who speaks Eng, people who speaks German, and people who speaks Eng and German
I want to get all of the people who speaks both English and German using Criteria.

this doesent work...

 crit.createAlias("languages", "l");
    Conjunction con = Restrictions.conjunction();
     for (int j = 0; j < o.length; j++) {
              Criterion tmp = Restrictions.eq("l.id", ((Languages)o[j]).getId());
             con.add(tmp);
     }
     crit.add(con);

   
     select
     this_.id as y0_,
        this_.lastName as y1_,
        this_.firstName as y2_,
        this_.socialNumber as y3_
    from
        Person this_ 
    inner join
        link_person_languages languages3_ 
            on this_.id=languages3_.Person_id 
    inner join
        Languages l1_ 
            on languages3_.languages_id=l1_.id 
    where
        (
            l1_.id=? 
            and l1_.id=?
