Dynamic lookup method

[loobiecore]

Hi,
I've got a factory object that uses lookup method injection to create instances.

<bean id="CONNECTION" class="ConnectionImpl" singleton="false">
...
</bean>	
<bean id="CONNECTION_FACTORY" class="ConnectionFactoryImpl" singleton="true">
<lookup-method name="createConnection"  bean="CONNECTION"/>
</bean>

I'd like to reuse the ConnectionFactoryImpl object in a new project but in this new context, ConnectionFactoryImpl can't be a singleton anymore and I'd like to switch between several implementations of Connection in the lookup method. Since the bean name is hard-coded in the lookup method, I wonder if there is a workarround to set this property dynamically without implementing ApplicationContextAware.

<bean id="CONNECTION" class="ConnectionImpl" singleton="false">
...
</bean>	
<bean id="ANOTHER_CONNECTION" class="AnotherConnectionImpl" singleton="false">
...
</bean>	
<bean id="CONNECTION_FACTORY" class="ConnectionFactoryImpl" singleton="false">
<lookup-method name="createConnection"  bean="??property_of_CONNECTION_FACTORY??"/>
</bean>

Thanks for help
