Erro hibernate

Oii pessoal estou com um problema com hibernate, o qual não consigo ver o erro...

tenho a entidade enquete;

import java.io.Serializable;
import java.util.List;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;

@Entity
public class Enquete implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    private int status;
    @Column(columnDefinition = "Text")
    private String pergunta;
    @Column(columnDefinition = "Text")
    private String questao1;
    private int questao1_votos;
    @Column(columnDefinition = "Text")
    private String questao2;
    private int questao2_votos;
    @Column(columnDefinition = "Text")
    private String questao3;
    private int questao3_votos;
    @Column(columnDefinition = "Text")
    private String questao4;
    private int questao4_votos;
    @OneToMany(mappedBy = "enquete")
    private List<ComentarioEnquete> comentarioEnquetes;

//gets e sets

e tenho outra que se chama ComentarioEnquete

import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.ManyToOne;

@Entity
public class ComentarioEnquete implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Integer id;
    private String nome;
    private String email;
    @Column(columnDefinition = "Text")
    private String comentario;
    @ManyToOne
    private Enquete enquete;

//gets e sets

e estou testando dessa forma...

public static void main(String args[]) {
        Enquete enquete = new Enquete();
        enquete.setPergunta("Oque você achou do site dukatitec?");
        enquete.setStatus(0);
        enquete.setQuestao1("Otimo");
        enquete.setQuestao1_votos(10);
        enquete.setQuestao2("Bom");
        enquete.setQuestao2_votos(23);
        enquete.setQuestao3("Regular");
        enquete.setQuestao3_votos(3);
        enquete.setQuestao4("Ruim");
        enquete.setQuestao4_votos(0);
        EnqueteDAO enqueteDAO = new EnqueteDAO();
        enqueteDAO.insertEnquete(enquete);

    }

só na hora que executo gera o seguinte erro...

metodo pra inserir

import br.com.dukatitec.enquete.entity.Enquete;
import br.com.dukatitec.utils.PrincipalDAO;
import javax.persistence.EntityTransaction;

import java.util.List;
import javax.persistence.Query;

public class EnqueteDAO extends PrincipalDAO {

    public void insertEnquete(Enquete enquete) {

        EntityTransaction t = getEm().getTransaction();
        t.begin();
        try {
            getEm().persist(enquete);
            t.commit();
        } catch (Exception e) {
            e.printStackTrace();
            t.rollback();
        }

    }
