hibernate连接oracle提示Unknow entity错误

啥也不说，直接贴代码：
Record类：
package com.tjpu.nic.model;import java.math.BigDecimal;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.SEQUENCE;
import javax.persistence.Id;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;/**
 * Record entity. @author MyEclipse Persistence Tools
 */
@SequenceGenerator(name = "generator",sequenceName="USERSQ")
@Entity
@Table(name = "RECORD", schema = "FACMANAGER")
public class Record implements java.io.Serializable { // Fields /**
 * 
 */
private static final long serialVersionUID = 1L;
private BigDecimal id;
private String name; // Constructors /** default constructor */
public Record() {
} /** full constructor */
public Record(String name) {
this.name = name;
} // Property accessors

@Id
@GeneratedValue(strategy = SEQUENCE, generator = "generator")
@Column(name = "ID", unique = true, nullable = false)
public BigDecimal getId() {
return this.id;
} public void setId(BigDecimal id) {
this.id = id;
} @Column(name = "NAME", nullable = false, length = 34)
public String getName() {
return this.name;
} public void setName(String name) {
this.name = name;
}}USERSQ已经在oracle中建立，hibernate.cfg.xml如下：
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"

<mapping class="com.tjpu.nic.model.Users" />
<mapping class="com.tjpu.nic.model.Record" />
</session-factory>
</hibernate-configuration>插入数据代码：
Session session=HibernateSessionFactory.getSessionFactory().getCurrentSession();
session.beginTransaction();
try {
System.out.println(r);
System.out.println(r.getName());
session.save(r);
System.out.println(r.getId());
session.getTransaction().commit();
flag=true;
} catch (HibernateException e) {
flag=false;
// TODO Auto-generated catch block
e.printStackTrace();
}
运行提示：
