my hibernate configuration is:

<session-factory>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="connection.url">jdbc:mysql://localhost:3306/test</property>
<property name="connection.username">root</property>
<property name="connection.password">root</property>

<mapping class="com.mytest.db.mapping.Test1"/>
</session-factory>


my POJO Test1 is:

package com.mytest.db.mapping;

import javax.persistence.*;

@Entity
@Table(name="test1")
public class Test1 {
@Id
private String test_id;

private String test_name;

private String test_description;

public String getTest_description() {
return test_description;
}

public void setTest_description(String test_description) {
this.test_description = test_description;
}

public String getTest_id() {
return test_id;
}

public void setTest_id(String test_id) {
this.test_id = test_id;
}

public String getTest_name() {
return test_name;
}

public void setTest_name(String test_name) {
this.test_name = test_name;
}
}


now I run the following code:

public class TestBA {

/**
* @param args
*/
public static void main(String[] args) {
Test1 test1 = new Test1();
test1.setTest_id("001");
test1.setTest_name("a");
test1.setTest_description("des1");

AnnotationConfiguration config = new AnnotationConfiguration();
sessionFactory = config.configure("hibernate.cfg.xml").buildSessionFactory();
Session session = sessionFactory.openSession();
Transaction tx = session.beginTransaction();
session.save(test1);
tx.commit();
}

}


but the I given the error:

Exception in thread "main" java.lang.NoClassDefFoundError: javax/persistence/InheritanceJoinColumns
at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:324)

at com.mytest.db.HibernateUtil.<clinit>(HibernateUtil.java:15)

why? where could I get the class javax/persistence/InheritanceJoinColumns?
