有人可以告诉我为什么出现以下错误吗？

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file:  java.naming.factory.initial

我得到期望的结果，并用数据填充 人员 表，但出现此错误。

这是我正在使用的代码： Person.java

@Entity
public class Person implements Serializable {
    private Integer id;
    private Address homeAddress;

    @Id
    @GeneratedValue
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }

    public Address getHomeAddress() {
        return homeAddress;
    }
    public void setHomeAddress(Address homeAddress) {
        this.homeAddress = homeAddress;
    }
}

地址.java

@Embeddable
public class Address implements Serializable {
    private String city;
    private String Country;

    public Address() {} 
    public Address(String city, String country) {
        super();
        this.city = city;
        Country = country;
    }

    public String getCity() {
        return city;
    }
    public void setCity(String city) {
        this.city = city;
    }
    public String getCountry() {
        return Country;
    }
    public void setCountry(String country) {
        Country = country;
    }
}

hibernate.cfg.xml

<hibernate-configuration>
 <session-factory name="">
  <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
  <property name="hibernate.connection.password">password</property>
  <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/mydb</property>

  <property name="hibernate.show_sql">true</property>
  <property name="hibernate.format_sql">true</property>

  <mapping class="com.transbinary.domain.Person"/>

 </session-factory>
</hibernate-configuration>

客户端程序

public class Client {
    public static void main(String[] args) {        
        SessionFactory sessionFactory =  new AnnotationConfiguration().configure().buildSessionFactory();
        Session session = sessionFactory.openSession();
        Transaction txn = session.beginTransaction();

        Person person = new Person();
        Address homeAddress = new Address("Mumbai", "India");
        person.setHomeAddress(homeAddress);

        session.save(person);

        txn.commit();
        session.close();            
    }
}

有人可以帮助我了解我为什么会收到该错误吗？

谢谢。
