Hibernate cascade deletes but does not save

UserprojectEntity has a OnetoMany relation with LinereferenceEntity. My cascade works for delete but not save.

UserprojectEntity:

  @XmlElementWrapper(name = "linereferencelist")
  @OneToMany(fetch = FetchType.LAZY,  mappedBy = "upl")
    @Cascade(CascadeType.ALL)
    @OrderBy("id ASC")
    public Collection<LinereferenceEntity> getLinereference() {
        return linereference;
    }

    public void setLinereference(Collection<LinereferenceEntity> linreference) {
        this.linereference = linreference;
    }

LinereferenceEntity:

 private UserprojectEntity upl;
    @XmlTransient
    @ManyToOne
    @JoinColumns({@JoinColumn(name = "user", referencedColumnName = "user", nullable = false,insertable = false,updatable = false), @JoinColumn(name = "project", referencedColumnName = "project", nullable = false,insertable = false,updatable = false)})
    public UserprojectEntity getUpl() {
        return upl;
    }

    public void setUpl(UserprojectEntity upl) {
        this.upl = upl;
    }
}

Calling program:


    private void deleteRecords(String sConfig, String sDelstring){
        SessionFactory sessionFactory = commonFuncs.getSessionFactory(sConfig) ;

        Session session = sessionFactory.openSession();
        Transaction transaction;

        transaction = session.beginTransaction();

        Query q = session.createQuery(sDelstring);

        Object upe = q.list().get(0);
        session.delete(upe);
        transaction.commit();
        session.close();

    }


 private void saveRecords(String sConfig, Object obj){
        SessionFactory sessionFactory = commonFuncs.getSessionFactory(sConfig) ;

        Session session = sessionFactory.openSession();
        Transaction transaction;
        transaction = session.beginTransaction();


        session.save(obj);

        transaction.commit();
        session.close();

    }
