Annexe 9 : Extraits de l’API javax.servlet.http

javax.servlet.http Class HttpServlet java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

All Implemented Interfaces: Serializable, Servlet, ServletConfig

public abstract class HttpServlet

extends GenericServlet

implements Serializable

Provides an abstract class to be subclassed to create an HTTP servlet suitable for a Web site. A subclass of HttpServlet

must override at least one method, usually one of these:

doGet, if the servlet supports HTTP GET requests

doPost, for HTTP POST requests

doPut, for HTTP PUT requests

doDelete, for HTTP DELETE requests

init and destroy, to manage resources that are held for the life of the servlet

getServletInfo, which the servlet uses to provide information about itself

Servlets typically run on multithreaded servers, so be aware that a servlet must handle concurrent requests and be careful

to synchronize access to shared resources. Shared resources include in-memory data such as instance or class variables

and external objects such as files, database connections, and network connections. See the Java Tutorial on Multithreaded

Programming for more information on handling multiple threads in a Java program.

Author: Various

Constructor Summary

HttpServlet()

Does nothing, because this is an abstract class.

Method Summary

void doTrace(HttpServletRequest req, HttpServletResponse resp)

Called by the server (via the service method) to allow a servlet to handle a TRACE request.

protected

long getLastModified(HttpServletRequest req)

Returns the time the HttpServletRequest object was last modified, in milliseconds since midnight January 1, 1970 GMT.
