Nested components

A nested component supports the main purpose of its container. Some key nested components for a container include the following:

• A Loader that manages a class loader that is used to load the classes needed by its container

• A Manager that manages the sessions that are associated with its container

• A Realm that provides access to a security domain for authenticating and authorizing users

• A Resources component that enables the lookup of static resources associated with its container

• A Valve component that is used to process the request and response for its container

Note

Not all of these components are applicable to all containers. For instance, a Loader is actually only used by the Context.
