使用JPA和hibernate在数据库中插入数据..但插入数据时出现问题

Question

我正在使用JPA和Hibernate，无法插入数据.. serviceImpl类：

package home;

import java.sql.Timestamp;
import java.text.SimpleDateFormat;


import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.EntityTransaction;
import javax.persistence.Persistence;

import com.order.OrderBook;

public class OrderServiceImpl implements OrderService {
@Override
public void add(OrderBook orderbook) {


    EntityManagerFactory emf=Persistence.createEntityManagerFactory("PU");
    System.out.println("in Get Users");
    EntityManager em=emf.createEntityManager();
    EntityTransaction et=em.getTransaction();
    et.begin();
    String timeStamp = 
            new SimpleDateFormat("dd-MM-yyyy:HH.mm.ss").
            format(new Timestamp(System.currentTimeMillis()));
    orderbook.setOrder_date(timeStamp);

    em.persist(orderbook);
    System.out.println("after persist");
        et.commit();
        System.out.println("Inserted");
    }
}

OrderBook.java

package com.order;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

import javax.persistence.Table;

@Entity
@Table(name = "order_book")

public class OrderBook {
    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private int order_id;
    private int client_id;
    private int broker_id;
    private String order_date;
    private int stock_id;
    private int price_per_share;
    private int no_of_share;
    private int total_amount;
    private String trade_type;

    public int getOrder_id() {
        return order_id;
    }
    public void setOrder_id(int order_id) {
        this.order_id = order_id;
    }


    public int getClient_id() {
        return client_id;
    }
    public void setClient_id(int client_id) {
        this.client_id = client_id;
    }
    public int getBroker_id() {
        return broker_id;
    }
    public void setBroker_id(int broker_id) {
        this.broker_id = broker_id;
    }

    public String getOrder_date() {
        return order_date;
    }
    public void setOrder_date(String order_date) {
        this.order_date =order_date;
    }

    public int getStock_id() {
        return stock_id;
    }
    public void setStock_id(int stock_id) {
        this.stock_id = stock_id;
    }
    public int getPrice_per_share() {
        return price_per_share;
    }
    public void setPrice_per_share(int price_per_share) {
        this.price_per_share = price_per_share;
    }
    public int getNo_of_share() {
        return no_of_share;
    }
    public void setNo_of_share(int no_of_share) {
        this.no_of_share = no_of_share;
    }
    public int getTotal_amount() {
        return total_amount;
    }
    public void setTotal_amount(int total_amount) {
        this.total_amount = total_amount;
    }
    public String getTrade_type() {
        return trade_type;
    }
    public void setTrade_type(String trade_type) {
        this.trade_type = trade_type;
    }
}

但在运行时我收到此错误。 upto persist（）方法正在执行但它没有执行commit（）方法。
