If you open javaranch.com or gmail.com you can see "Log me automatically on each request" or "Remeber me on this computer" respectively. How can one implement that. I am using Web container based authentication and authoriazation. (web.xml based security). I did find a thread on this in the JSP form but the link pointed there is broken and the implementation is not clear on how to implement the above functionality.
You can use a cookie to enable when a user selects this option. Now when a page loads, put a check to identify that cookie, if that cookie is null or not there then just load the login page or if it contains value then fetch username/password from that cookie and load a logged in page.
