Yes HTTP is stateless, meaning every request is
being treated as a new one and
state (data) will not be
shared between two http requests, but Servlet
API
provide the some mechanisms address this issue. Below
are Servlet
state management techniques.
i) Use POST/GET variables to pass info from page to
page. (Hidden Variables)
<input
type='hidden'
name='userName'>
request.getParameter
('userName');
ii) Use the
session to store information.
session.setAttribute("userName",
"testUser");
value =
session.getAttribute("userName");
iii) Use cookies to store information.
Cookie
cookie = new Cookie("CName","Cookie
Value");
cookie.setMaxAge(100);
response.addCookie(cookie);
