PropertyPlaceholderConfigurer with Hibernate.cfg.xml

Question

I have 2 files that need to be linked together: hibernate.cfg.xml and hibernate. How can I point them to each other using PropertyPlaceholderConfigurer? Is this possible without beans declaration? (I'm new to Spring). Each answer is evaluated.

Thanks in advance.

hibernate.cfg.xml:

, Factory. . , -, hibernate.cfg.xml , bean -. , bean.

, hibernate.properties, .

<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"
p:location="{location of hibernate properties files}" />

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="${db.driverClassName}"/>
    <property name="jdbcUrl" value="${db.databaseurl}"/>
    ....other properties...
</bean>

, factory

<beans:bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <beans:property name="dataSource" ref="dataSource" />
        <beans:property name="configLocation">
