The jakarta.servlet.http package contains a number of classes and interfaces that describe and define the contracts between a servlet class running under the HTTP protocol and the runtime environment provided for an instance of such a class by a conforming servlet container.
Interface Summary Interface Description HttpServletMappingRepresents how the request from which this object was obtained was mapped to the associated servlet. HttpServletRequestExtends the
ServletRequestinterface to provide request information for HTTP servlets.
ServletResponseinterface to provide HTTP-specific functionality in sending a response.
HttpSessionProvides a way to identify a user across more than one page request or visit to a Web site and to store information about that user. HttpSessionActivationListenerObjects that are bound to a session may listen to container events notifying them that sessions will be passivated and that session will be activated. HttpSessionAttributeListenerThis listener interface can be implemented in order to get notifications of changes to the attribute lists of sessions within this web application. HttpSessionBindingListenerCauses an object to be notified when it is bound to or unbound from a session. HttpSessionIdListenerImplementations of this interface are notified when an

WebConnectionThe interface used by an
HttpUpgradeHandlerto interact with an upgraded HTTP connection.
Class Summary Class Description CookieCreates a cookie, a small amount of information sent by a servlet to a Web browser, saved by the browser, and later sent back to the server. HttpFilterProvides a base class that implements the Filter interface and ensures that the Request and Response are of type HttpServletRequest and HttpServletResponse respectively. HttpServletProvides an abstract class to be subclassed to create an HTTP servlet suitable for a Web site. HttpServletRequestWrapperProvides a convenient implementation of the HttpServletRequest interface that can be subclassed by developers wishing to adapt the request to a Servlet. HttpServletResponseWrapperProvides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet.
