Не создается таблица в mapping Hibernate

Почему-то не создается таблица. Прописал мэппинг, указал его в hibernate.cfg.xml. Сессию создает, а таблица не создается.

user.cfg.xml

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
        "-//Hibernate/Hibernate Mapping DTD//EN"
        "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
    <class name="User" table="users">
        <id name="id" type="int" column="id">
            <generator class="native"/> <!--autoincrement-->
        </id>
        <property name="firstname" column="first_name" type="string"/>
        <property name="lastname" column="last_name" type="string"/>
        <property name="age" column="age" type="int"/>
    </class>
</hibernate-mapping>

hibernate.cfg.xml:

<?xml version="1.0" encoding="utf-8"?>

Java класс:

public class User {
    private int id;
    private String firstname;
    private String lastname;
    private int age;
    public User() {
    }
    public User(int id) {
        this.id = id;
    }

    public void setId(int id) {
        this.id = id;
    }
    public int getId() {
        return id;
    }
    public String getFirstname() {
        return firstname;
    }
    public void setFirstname(String firstname) {
        this.firstname = firstname;
    }
    public String getLastname() {
        return lastname;
    }
    public void setLastname(String lastname) {
        this.lastname = lastname;
    }
    public int getAge() {
        return age;`введите сюда код`
    }
    public void setAge(int age) {
        this.age = age;
    }
}
