Question

        private String id;

         //other getters setters
    }


    @Entity

    public class Student {
        @Id
        @Column(name = "sid")
        @GeneratedValue(generator = "uuid")
        private String id;
    @ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
        @JoinTable(name = "stu_cou", joinColumns = {@JoinColumn(name = "sid", nullable = false)}, inverseJoinColumns = { @JoinColumn(name = "cid", nullable = true) })

You could use a NamedQuery in your Courses Entity with a join.
