Hello, I am trying to use native MySQL's MD5 crypto func, so I defined custom insert in my mapping file.

<hibernate-mapping package="tutorial">
  <class name="com.xorty.mailclient.client.domain.User" table="user">
    <id name="login" type="string" column="login"></id>
    <property name="password">
        <column name="password" />
    </property>
    <sql-insert>INSERT INTO user (login,password) VALUES ( ?, MD5(?) )</sql-insert>
  </class>
</hibernate-mapping>

Then I create User (pretty simple POJO with just 2 Strings - login and password) and try to persist it.

session.beginTransaction();
// we have no such user in here yet
User junitUser = (User) session.load(User.class, "junit_user");
assert (null == junitUser);
// insert new user
junitUser = new User();
junitUser.setLogin("junit_user");
junitUser.setPassword("junitpass");
session.save(junitUser);
session.getTransaction().commit();

What actually happens?

User is created, but with reversed parameters order. He has login "junitpass" and "junit_user" is MD5 encrypted and stored as password.

What did I wrong? Thanks

EDIT: ADDING POJO class
