Package javax.servlet

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.

          Description

Interface Summary
AsyncContext Class representing the execution context for an asynchronous operation that was initiated on a ServletRequest.
AsyncListener Listener that will be notified in the event that an asynchronous operation initiated on a ServletRequest to which the listener had been added has completed, timed out, or resulted in an error.
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 allows a library/runtime to be notified of a web application's startup phase and perform any required programmatic registration of servlets, filters, and listeners in response to it.
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 the asynchronous operation initiated on a ServletRequest (via a call to ServletRequest#startAsync or ServletRequest#startAsync(ServletRequest, ServletResponse)) has completed, timed out, or produced an error.
GenericServlet Defines a generic, protocol-independent servlet.
HttpConstraintElement Java Class representation of an HttpConstraint annotation value.
HttpMethodConstraintElement Java Class represntation of an HttpMethodConstraint annotation value.
MultipartConfigElement Java Class represntation of an MultipartConfig annotation value.
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.
ServletSecurityElement Java Class represntation of a ServletSecurity annotation value.
 

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.
