Uses of Package
javax.servlet

Packages that use javax.servlet

Package	Description
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.
javax.servlet.annotation	The javax.servlet.annotation package contains a number of annotations that allow users to use annotations to declare servlets, filters, listeners and specify the metadata for the declared component.
javax.servlet.http	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.

Classes in javax.servlet used by javax.servlet

Class	Description
AsyncContext	Class representing the execution context for an asynchronous operation that was initiated on a ServletRequest.
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.
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.
DispatcherType	Enumeration of filter dispatcher types.
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.
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.
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.
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.
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.
ServletException	Defines a general exception a servlet can throw when it encounters difficulty.
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.
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.
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.
ServletResponse	Defines an object to assist a servlet in sending a response to the client.
ServletSecurityElement	Java Class represntation of a ServletSecurity annotation value.
SessionCookieConfig	Class that may be used to configure various properties of cookies used for session tracking purposes.
SessionTrackingMode	Enumeration of session tracking modes.
WriteListener	Callback notification mechanism that signals to the developer it's possible to write content without blocking.

ServletResponse	Defines an object to assist a servlet in sending a response to the client.
ServletResponseWrapper	Provides a convenient implementation of the ServletResponse interface that can be subclassed by developers wishing to adapt the response from a Servlet.
