Interface Summary

Interface	Description
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.
ReadListener	This class represents a call-back mechanism that will notify implementations as HTTP request data becomes available to be read without blocking.
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.
WriteListener	Callback notification mechanism that signals to the developer it's possible to write content without blocking.

Class Summary

Class	Description
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.
GenericFilter	Defines a generic, protocol-independent filter.
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 representation of a ServletSecurity annotation value.

Enum Summary

Enum	Description

Exception Summary

Exception	Description
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.
