Package jakarta.servlet.http

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
HttpServletMapping	Represents how the request from which this object was obtained was mapped to the associated servlet.
HttpServletRequest	Extends the ServletRequest interface to provide request information for HTTP servlets.
HttpServletResponse	Extends the ServletResponse interface to provide HTTP-specific functionality in sending a response.
HttpSession	Provides 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.
HttpSessionActivationListener	Objects that are bound to a session may listen to container events notifying them that sessions will be passivated and that session will be activated.
HttpSessionAttributeListener	This listener interface can be implemented in order to get notifications of changes to the attribute lists of sessions within this web application.
HttpSessionBindingListener	Causes an object to be notified when it is bound to or unbound from a session.
HttpSessionContext	Deprecated. As of Java(tm) Servlet API 2.1 for security reasons, with no replacement.
HttpSessionIdListener	Implementations of this interface are notified when an HttpSession's ID changes.
HttpSessionListener	Implementations of this interface are notified of changes to the list of active sessions in a web application.
HttpUpgradeHandler	Interface between the HTTP upgrade process and the new protocol.
Part	This class represents a part as uploaded to the server as part of a multipart/form-data request body.
PushBuilder	Builds a push request based on the HttpServletRequest from which this builder was obtained.
WebConnection	The interface used by an HttpUpgradeHandler to interact with an upgraded HTTP connection.

Class Summary

Class	Description
Cookie	Creates 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.
HttpFilter	Provides a base class that implements the Filter interface and ensures that the Request and Response are of type HttpServletRequest and HttpServletResponse respectively.
HttpServlet	Provides an abstract class to be subclassed to create an HTTP servlet suitable for a Web site.
HttpServletRequestWrapper	Provides a convenient implementation of the HttpServletRequest interface that can be subclassed by developers wishing to adapt the request to a Servlet.
HttpServletResponseWrapper	Provides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet.
HttpSessionBindingEvent	Events of this type are either sent to an object that implements HttpSessionBindingListener when it is bound or unbound from a session, or to an HttpSessionAttributeListener that has been configured in the deployment descriptor when any attribute is bound, unbound or replaced in a session.
HttpSessionEvent	This is the class representing event notifications for changes to sessions within a web application.
HttpUtils	Deprecated. As of Java(tm) Servlet API 2.3.
