Common.cfc has to be managed by ColdSpring for the dependency
injection to take place. I.e., you need:
<bean id="common" class="model.Common"> ... etc ... </bean>
And you need to get the "common" bean from ColdSpring wherever you use it.
Your XML has the bean named userGateway which doesn't seem right
(since you have a property injector method in Common.cfc for
userGateway)?
