∟Methods Supported by the "session" Object

This section describes methods supported by the 'session' implicit object provided by the JSP container.

session: An implicit object provided by the JSP container to hold information and methods common to all JSP pages running under one session. The session object is an instance of a class that implements the javax.servlet.http.HttpSession interface defined by the J2EE specification.

Here are some methods provided by the 'session' object:

getAttribute(): Returns the object that is associated to the specified key string previously saved in the session.
getAttributeNames(): Returns an Enumeration object that contains all the key strings saved in the session.
getCreationTime(): Returns the time when this session was created, measured in milliseconds since midnight January 1, 1970 GMT.
getId(): Returns the session ID as a string.
setAttribute(): Save an object with the specified key string in the session so that it can be used by the same or another request later in the same session.
getServletContext(): Returns the ServletContext to which this session belongs.
getMaxInactiveInterval(): Returns the maximum time interval, in seconds, that the servlet container will keep this session open between client accesses.
invalidate(): Invalidates this session then unbinds any objects bound to it.
