Description
Interface Summary | |
---|---|
AsyncContext | Class representing the execution context for an asynchronous operation that was started on a ServletRequest. |
AsyncListener | Listener that will be notified when an asynchronous operation that was
started on a ServletRequest by a call to ServletRequest#startAsync
or ServletRequest#startAsync(ServletRequest, ServletResponse)
completes or times out. |
Filter | A filter is an object that performs filtering tasks on either the request to a resource (a servlet or static content), or on the response from a resource, or both. |
FilterChain | A FilterChain is an object provided by the servlet container to the developer giving a view into the invocation chain of a filtered request for a resource. |
FilterConfig | A filter configuration object used by a servlet container to pass information to a filter during initialization. |
FilterRegistration | Interface through which a Filter may be further configured. |
FilterRegistration.Dynamic | Interface through which a Filter registered via one of the
addFilter methods on ServletContext may be further
configured. |
Registration | Interface through which a Servlet or Filter may be
further configured. |
Registration.Dynamic | Interface through which a Servlet or Filter registered
via one of the addServlet or addFilter methods,
respectively, on ServletContext may be further configured. |
RequestDispatcher | Defines an object that receives requests from the client and sends them to any resource (such as a servlet, HTML file, or JSP file) on the server. |
Servlet | Defines methods that all servlets must implement. |
ServletConfig | A servlet configuration object used by a servlet container to pass information to a servlet during initialization. |
ServletContainerInitializer | Interface which may be implemented by a library/runtime in order
to be notified by the container of any of the classes/interfaces
in which it has expressed interest via the
HandlesTypes annotation. |
ServletContext | Defines a set of methods that a servlet uses to communicate with its servlet container, for example, to get the MIME type of a file, dispatch requests, or write to a log file. |
ServletContextAttributeListener | Interface for receiving notification events about ServletContext attribute changes. |
ServletContextListener | Interface for receiving notification events about ServletContext lifecycle changes. |
ServletRegistration | Interface through which a Servlet may be further configured. |
ServletRegistration.Dynamic | Interface through which a Servlet registered via one of the
addServlet methods on ServletContext may be further
configured. |
ServletRequest | Defines an object to provide client request information to a servlet. |
ServletRequestAttributeListener | Interface for receiving notification events about ServletRequest attribute changes. |
ServletRequestListener | Interface for receiving notification events about requests coming into and going out of scope of a web application. |
ServletResponse | Defines an object to assist a servlet in sending a response to the client. |
SessionCookieConfig | Class that may be used to configure various properties of cookies used for session tracking purposes. |
SingleThreadModel | Deprecated. As of Java Servlet API 2.4, with no direct replacement. |
Class Summary | |
---|---|
AsyncEvent | Event that gets fired when a ServletRequest on which asynchronous
processing was started has finished processing through a call to
AsyncContext#complete or has timed out. |
GenericServlet | Defines a generic, protocol-independent servlet. |
ServletContextAttributeEvent | Event class for notifications about changes to the attributes of the ServletContext of a web application. |
ServletContextEvent | This is the event class for notifications about changes to the servlet context of a web application. |
ServletInputStream | Provides an input stream for reading binary data from a client
request, including an efficient readLine method
for reading data one line at a time. |
ServletOutputStream | Provides an output stream for sending binary data to the client. |
ServletRequestAttributeEvent | This is the event class for notifications of changes to the attributes of the servlet request in an application. |
ServletRequestEvent | Events of this kind indicate lifecycle events for a ServletRequest. |
ServletRequestWrapper | Provides a convenient implementation of the ServletRequest interface that can be subclassed by developers wishing to adapt the request to a Servlet. |
ServletResponseWrapper | Provides a convenient implementation of the ServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet. |
Enum Summary | |
---|---|
DispatcherType | Enumeration of filter dispatcher types. |
SessionTrackingMode | Enumeration of session tracking modes. |
Exception Summary | |
---|---|
ServletException | Defines a general exception a servlet can throw when it encounters difficulty. |
UnavailableException | Defines an exception that a servlet or filter throws to indicate that it is permanently or temporarily unavailable. |
The javax.servlet package contains a number of classes and interfaces that describe and define the contracts between a servlet class and the runtime environment provided for an instance of such a class by a conforming servlet container.
