trying to Configur c3p0 pooling in Hibernate using Spring WebFlow

Question

I am Configuring the built-in c3p0 pooling in Hibernate using Spring but its giving me error it does not like any of the C3P0 stuff like:

<prop name="hibernate.c3p0.min_size" value="2" />
<prop name="hibernate.c3p0.max_size" value="5" />

Can someone please tell me why?

<bean id="sessionFactory" class="org.springframework.orm.hibernate.LocalSessionFactoryBean">
    <!--suppress InjectionValueTypeInspection -->
    <property name="mappingResources" ref="hibernateMappingList" />
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">net.sf.hibernate.dialect.Oracle9Dialect</prop>
            <prop key="transaction.factory_class">
                net.sf.hibernate.transaction.JDBCTransactionFactory
            </prop>
            <prop key="hibernate.transaction.factory_class">
                net.sf.hibernate.transaction.JDBCTransactionFactory
            </prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.cglib.use_reflection_optimizer">false</prop>
            <prop key="hibernate.jdbc.batch_size">0</prop>

            <prop name="hibernate.c3p0.min_size" value="2" />
            <prop name="hibernate.c3p0.max_size" value="5" />
            <prop name="hibernate.c3p0.timeout" value="600" />
            <prop name="hibernate.c3p0.max_statements" value="0" />
            <prop name="hibernate.c3p0.idle_test_period" value="300"/>
            <prop name="hibernate.c3p0.acquire_increment" value="1" />
      </props>
    </property>
</bean>

Here is my database source information:

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
        destroy-method="close">

        <!-- these are C3P0 properties -->
        <property name="acquireIncrement" value="${database.acquireIncrement}" />
        <property name="minPoolSize" value="${database.minPoolSize}" />
        <property name="maxPoolSize" value="${database.maxPoolSize}" /> 
        <property name="maxIdleTime" value="${database.maxIdleTime}" />

        <property name="driverClass" value="${database.driver}" />
        <property name="jdbcUrl" value="${database.url}" />
        <property name="user" value="${database.user}" />
        <property name="password" value="${database.password}" />
    </bean>

The XML is wrong. In the following section

       <prop name="hibernate.c3p0.min_size" value="2" />
       <prop name="hibernate.c3p0.max_size" value="5" />
       <prop name="hibernate.c3p0.timeout" value="600" />
       <prop name="hibernate.c3p0.max_statements" value="0" />
       <prop name="hibernate.c3p0.idle_test_period" value="300"/>
       <prop name="hibernate.c3p0.acquire_increment" value="1" />

replace it using the same format as with the other properties

       <prop key="key">value</prop>

The prop element uses different attributes than the property element.
