I am not 100% sure about this because I haven't tried this yet. Let me
know if this worked out for you. Probably two things need to be done.
1) set GeneralContainer's ServiceManager as SpecialContainer's
ServiceManager's parent.
2) set GeneralContainer's child Context as SpecialContainer's Context's
parent.
<snippet>
FortressConfig config = new FortressConfig();
// general configuration...
config.setContextDirectory( generalContextDirectory );
config.setContainerConfiguration( "./general.xconf" );
ContextManager contextManager = new ContextManager( config.getContext()
);
ContainerUtil.initialize( contextManager );
DefaultContainerManager containerManager = new DefaultContainerManager(
contextManager );
ContainerUtil.initialize( containerManager );
final DefaultContainer generalContainer =
containerManager.getContainer();
// see 2)
config = new FortressConfig( contextManager.getChildContext() );
// see 1)
config.setServiceManager( generalContainer.getServiceManager() );
// special configuration ...
config.setContextDirectory( specialContextDirectory );
config.setContainerConfiguration( "./special.xconf" );
containerManager = new DefaultContainerManager( config.getContext() );
ContainerUtil.initialize( containerManager );
final DefaultContainer specialContainer =
containerManager.getContainer();
</snipped>
