StandardService

The default implementation of the org.apache.catalina.Service interface that is used, if no class name override is specified in the server.xml file, is org.apache.catalina.core.StandardService. This instance does nothing more than provide an organizational mechanism to hook multiple Connector instances to a single Engine instance. It is also responsible for the lifecycle invocations on its contained children. For instance, its start() method invokes start() on its single Engine instance, on all of its Executor instances, as well as on all of its Connector instances.

Similarly, it supports methods that support the registration and removal of its children from its containment structure. For example, the addConnector(), removeConnector(), and findConnectors() methods let you manage the Connector instances that are associated with a given Service.

By default, no listeners are registered with a given Service instance.
