JBoss Modular Service Container (JBoss MSC)

JBoss MSC is a lightweight highly concurrent dependency injection container for Java. It is built on three key abstractions: "Service", "Service controller" and "Service container".Every service has two lifecycle phases - "start phase" and "stop phase". Services can start and stop either "synchronously" or "asynchronously".Every service once successfully installed into service container has associated service controller with it. Service controllers are useful for adding / removing lifecycle listeners to / from services at runtimeor can be used to retrieve some information about service such as its name, mode, state or unavailable dependencies.Service container provides information about installed services and provides methods for retrieving service controllers associated with those services.
