我将模型类保存在com.anand.model.Employee.java中，并且正确地在sdnext-
servlet.xml中提到了annotatedClasses。但是我仍然遇到错误。请帮我解决这个问题。

sdnext-servlet.xml

<bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="annotatedClasses">
            <list>
                <value>com.anand.model.Employee</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">${hibernate.dialect}</prop>
                <prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
                <prop key="hibernate.hbm2ddl.auto">${hibernate.hbm2ddl.auto}</prop>             
            </props>
        </property>
    </bean>
