Hi,
I mean,
change your first blueprint like
< service id="containerManagerId" ref="containerManager"
interface="de.kisters.project.domain.api.session.container.IContainerManager">
</service>
<bean id="containerManager"
class="de.kisters.project.domain.impl.session.container.ContainerManager"
/>
and in the second blueprint file refer the bean id but not the service id.
something like
<bean
class="de.kisters.project.domain.impl.session.repository.RepositoryFactory"
init-method="activate" destroy-method="deactivate">
<property name="containerManager" ref="containerManager"
/>
</bean>
this should be good.
