The javax.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.
ClassDescriptionCreates 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.Provides a base class that implements the Filter interface and ensures that the Request and Response are of type HttpServletRequest and HttpServletResponse respectively.Provides an abstract class to be subclassed to create an HTTP servlet suitable for a Web site.Represents how the request from which this object was obtained was mapped to the associated servlet.Extends the
ServletRequestinterface to provide request information for HTTP servlets.Provides a convenient implementation of the HttpServletRequest interface that can be subclassed by developers wishing to adapt the request to a Servlet.Extends the
ServletResponseinterface to provide HTTP-specific functionality in sending a response.Provides a convenient implementation of the HttpServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet.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.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.This listener interface can be implemented in order to get notifications of changes to the attribute lists of sessions within this web application.Causes an object to be notified when it is bound to or unbound from a session.Deprecated.As of Java(tm) Servlet API 2.1 for security reasons, with no replacement.This is the class representing event notifications for changes to sessions within a web application.Implementations of this interface are notified when an
HttpSession's ID changes.Implementations of this interface are notified of changes to the list of active sessions in a web application.Interface between the HTTP upgrade process and the new protocol.Deprecated.As of Java(tm) Servlet API 2.3.Represents the ways that a request can be mapped to a servletThis class represents a part as uploaded to the server as part of a
multipart/form-datarequest body.Builds a push request based on the
HttpServletRequestfrom which this builder was obtained.The interface used by an
HttpUpgradeHandlerto interact with an upgraded HTTP connection.
