Hi
If u maintain the data along with the many request ,then we need to maintain the session. if u want to maintain the session,first u can create session given below
HttpSessio session=ServletContext.getSession();
if u want to put the data in session,Then
session.setAttribute("key","value");//here key and values are same
if u want to get the data from session,then
session.getAttribute("key");
Like that u can maintain the session
