Hibernate学习第一步

今天我在网上查的Hibernate学习的基础的第一个简单例子。

实体类代码如下：

package domain;

public class News {
	
	//news members
	private Integer userID;
	private String userName;
	private String rname;
	private String pwd;
	private String sex;
	public Integer getUserID() {
		return userID;
	}
	public void setUserID(Integer userID) {
		this.userID = userID;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getRname() {
		return rname;
	}
	public void setRname(String rname) {
		this.rname = rname;
	}
	public String getPwd() {
		return pwd;
	}
	public void setPwd(String pwd) {
		this.pwd = pwd;
	}
	public String getSex() {
		return sex;
	}
	public void setSex(String sex) {
		this.sex = sex;
	}
	public String getEmail() {
		return email;
	}
	public void setEmail(String email) {
		this.email = email;
	}
	private String email;
	

}

main方法类代码如下：

package lee;

import org.hibernate.*;
import org.hibernate.cfg.*;
import domain.*;

public class NewsManager {
	
	
	public static void main(String[] args)throws Exception
	{
		//实例化Configuration；configure（）方法会负责加载hibernate.cfg.xml文件
		Configuration cOnf= new Configuration().configure("hibernate.cfg.xml");
		
		//create SessionFactory
		
		@SuppressWarnings("deprecation")
		SessionFactory sf = conf.buildSessionFactory();
		
		//create Session
		Session sess = sf.openSession();
		
		//create transaction
		Transaction tx = sess.beginTransaction();
		
		//To insert data in db by the method
		News n = new News();
		n.setEmail("af");
		n.setPwd("124");
		n.setRname("a");
		n.setSex("male");
		n.setUserID(1314321);
		n.setUserName("fasfdas");
		
		//save,execute save() insert data into db, commit()
		sess.save(n);
		tx.commit();
		
		//close Session
		sess.close();
		sf.close();
	}

}

XXX.cfg.xml的配置：

		"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
		"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

    
        com.microsoft.jdbc.sqlserver.SQLServerDriver
        123456as
        jdbc:sqlserver://localhost:1433;DatabaseName=login
        sa
        true
        update
        org.hibernate.dialect.SQLServerDialect
        
    

XXX.hbm.xml的配置

可是在写完代码时，出现以下错误：
我导入的jar包为：
以上是通过build path导入的。
现在还在寻求解决办法。
