Interface Summary

Interface	Description
Auditor	Defines interface of classes which implement audit functionality.
Authenticator	An Authenticator is a component (usually a Valve or Container) that provides some sort of authentication service.
CometEvent	The CometEvent interface.
Connector	A Connector is a component responsible receiving requests from, and returning responses to, a client application.
Contained	Decoupling interface which specifies that an implementing class is associated with at most one Container instance.
Container	A Container is an object that can execute requests received from a client, and return responses based on those requests.
ContainerListener	Interface defining a listener for significant Container generated events.
ContainerServlet	A ContainerServlet is a servlet that has access to Catalina internal functionality, and is loaded from the Catalina class loader instead of the web application class loader.
Context	A Context is a Container that represents a servlet context, and therefore an individual web application, in the Catalina servlet engine.
Deployer	A Deployer is a specialized Container into which web applications can be deployed and undeployed.
Engine	An Engine is a Container that represents the entire Catalina servlet engine.
Host	A Host is a Container that represents a virtual host in the Catalina servlet engine.
HttpRequest	An HttpRequest is the Catalina internal facade for an HttpServletRequest that is to be processed, in order to produce the corresponding HttpResponse.
HttpResponse	An HttpResponse is the Catalina-internal facade for an HttpServletResponse that is to be produced, based on the processing of a corresponding HttpRequest.
InstanceListener	Interface defining a listener for significant events related to a specific servlet instance, rather than to the Wrapper component that is managing that instance.
Lifecycle	Common interface for component life cycle methods.
LifecycleListener	Interface defining a listener for significant events (including "component start" and "component stop" generated by a component that implements the Lifecycle interface.
Loader	A Loader represents a Java ClassLoader implementation that can be used by a Container to load class files (within a repository associated with the Loader) that are designed to be reloaded upon request, as well as a mechanism to detect whether changes have occurred in the underlying repository.
Logger	A Logger is a generic interface for the message and exception logging methods of the ServletContext interface.
Manager	A Manager manages the pool of Sessions that are associated with a particular Container.
Pipeline	Interface describing a collection of Valves that should be executed in sequence when the invoke() method is invoked.
Realm	A Realm is a read-only facade for an underlying security realm used to authenticate individual users, and identify the security roles associated with those users.
Request	A Request is the Catalina-internal facade for a ServletRequest that is to be processed, in order to produce the corresponding Response.
Response	A Response is the Catalina-internal facade for a ServletResponse that is to be produced, based on the processing of a corresponding Request.
Server	A Server element represents the entire Catalina servlet container.
Service	A Service is a group of one or more Connectors that share a single Container to process their incoming requests.
Session	A Session is the Catalina-internal facade for an HttpSession that is used to maintain state information between requests for a particular user of a web application.
SessionListener	Interface defining a listener for significant Session generated events.
SessionLocker
Store	A Store is the abstraction of a Catalina component that provides persistent storage and loading of Sessions and their associated user data.
Valve	A Valve is a request processing component associated with a particular Container.
Wrapper	A Wrapper is a Container that represents an individual servlet definition from the deployment descriptor of the web application.

Class Summary

Class	Description
ContainerEvent	General event for notifying listeners of significant changes on a Container.
Globals	Global constants that are applicable to multiple packages within Catalina.
InstanceEvent	General event for notifying listeners of significant events related to a specific instance of a Servlet, or a specific instance of a Filter, as opposed to the Wrapper component that manages it.
LifecycleEvent	General event for notifying listeners of significant changes on a component that implements the Lifecycle interface.
LogFacade	Provides the logging facilities.
ServerFactory	ServerFactory allows the registration of the (singleton) Server instance for this JVM, so that it can be accessed independently of any existing reference to the component hierarchy.
SessionEvent	General event for notifying listeners of significant changes on a Session.

Enum Summary

Enum	Description
CometEvent.EventSubType	Event details TIMEOUT - the connection timed out (sub type of ERROR); note that this ERROR type is not fatal, and the connection will not be closed unless the servlet uses the close method of the event CLIENT_DISCONNECT - the client connection was closed (sub type of ERROR) IOEXCEPTION - an IO exception occurred, such as invalid content, for example, an invalid chunk block (sub type of ERROR) WEBAPP_RELOAD - the webapplication is being reloaded (sub type of END) SERVER_SHUTDOWN - the server is shutting down (sub type of END) SESSION_END - the servlet ended the session (sub type of END)
CometEvent.EventType	Enumeration describing the major events that the container can invoke the CometProcessors event() method with BEGIN - will be called at the beginning of the processing of the connection.
InstanceEvent.EventType

Exception Summary

Exception	Description
LifecycleException	General purpose exception that is thrown to indicate a lifecycle related problem.
