Hibernate Transactions wont roll-back while testing

Question

I'm working with Spring 3 , and I use Hibernate3 as the O/R mapper.While testing my DAO classes I intended to declare my test classes as @Transactional, so that I could rollback the stuff in my DB. DAO classes work fine, however the rollback never happens. this is how my test class looks like:

    @BeforeTransaction
    public void createTestData() {
            // instantiate User objects
    }

    @Before
    public void insertTestData() {
        jdbcTemplate.update("INSERT INTO USER VALUES" + user1);
        jdbcTemplate.update("INSERT INTO USER VALUES" + user2);
        jdbcTemplate.update("INSERT INTO USER VALUES" + user3);
        }

    @Test
    @Rollback(true)
    public void testCheckAvailability() {
        boolean trueResult = userDao.checkAvailability("shaaadi");
        boolean falseResult = userDao.checkAvailability("elthefar");
            assertEquals("Invalid output", true, trueResult);
            assertEquals("Invalid output", false, falseResult);
    }


}

not to forget about the xml file contents:

        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
        p:dataSource-ref="dataSource">
        <property name="annotatedClasses">
        <list>
            <value>ir.cms.domain.user.User</value>
        </list>
        </property>
        <property name="hibernateProperties">
            <value>
            hibernate.format_sql=true
            hibernate.dialect=org.hibernate.dialect.MySQLDialect
            </value>
        </property>
    </bean>

        <bean id="transactionManager" 
          class="org.springframework.orm.hibernate3.HibernateTransactionManager"
          p:sessionFactory-ref="sessionFactory" />



    <bean id="userDao" 
        class="ir.cms.dao.user.impl.UserDaoImpl"
        p:sessionFactory-ref="sessionFactory" />



</beans>

Finally , I should add that DAO classes are not transactional , and are only annotated as @Repository. I appreciate any suggestion :)

My Problem is finally solved. I was using MySQL, and InnoDB mode was off.
