|
ContainerListener |
Interface defining a listener for significant Container generated events.
|

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.
|

|
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.
