我在使用hibernate时遇到以下错误。你能找出这个错误的原因吗。

org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition.

我在applicationcontext.xml文件中定义了如下会话工厂bean，并从单独的文件database.properties获取数据库连接值。

<bean id="SessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
    <property name="dataSource" ref="JobDataSource" />
    <property name="mappingResources">
        <list>

            <value>Entry.hbm.xml</value>
            <value>AccountMapping.hbm.xml</value>

        </list>
    </property>
    <property name="hibernateProperties">
         <props>
            <prop key="hibernate.show_sql">true</prop>
            <prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
         </props>
    </property>
</bean>

请帮助我解决这个错误和这个错误的原因。谢谢你的帮助
