You can use <code>cookies</code> for this purpose.

In your servlet response handler (doPost, doGet etc.) create a cookie in the following way - 

<pre><code>if(remember_me_is_checked)
{
 Cookie c = new Cookie("userid", userId.toString());
 c.setMaxAge(24*60*60);
 response.addCookie(c); // response is an instance of type HttpServletReponse
}
</code></pre>

To read them, you can use something like this - 

<pre><code>Cookie[] cookies = request.getCookies(); // request is an instance of type 
 //HttpServletRequest
boolean foundCookie = false;

for(int i = 0; i &lt; cookies.length; i++)
{ 
 Cookie c = cookies[i];
 if (c.getName().equals("userid"))
 {
 string userId= c.getValue();
 foundCookie = true;
 }
} 
</code></pre>

<a href="http://docs.oracle.com/javaee/1.4/api/javax/servlet/http/Cookie.html" rel="nofollow">Here</a> is the official documentation for the <code>Cookie</code> class.

You can use cookies to help with your implementation. Something like this . 

<pre><code>String userIdendificationKey="UserName";

 Cookie cookie = new Cookie ("userIdendificationKey",userIdendificationKey);
// Set the age of the cokkie
 cookie.setMaxAge(365 * 24 * 60 * 60);
//Then add the cookies to the response
 response.addCookie(cookie);
</code></pre>

and then check against the particular value later .

I don't know whether it is secure or not,but this is what i did.

In login.jsp head tag

<pre><code>&lt;script type="text/javascript"&gt;
var isLoggedIn = "${isLoggedIn}";
if(isLoggedIn === true)
 window.location.href="Home.jsp";
&lt;/script&gt;
</code></pre>

in body tag i added a check box for Remember Me as below

<pre><code>&lt;input type="checkbox" id="RememberMe" name="rememberMe"&gt;
&lt;label for="RememberMe"&gt;Remember Me&lt;/label&gt;
</code></pre>

In servlet doPost method i added the code below

<pre><code>if(userdetails are verified)
 { 
 if(request.getParameter("rememberMe")!=null){
 request.getSession().setAttribute("isLoggedIn", true);
 }
 RequestDispatcher rs = request.getRequestDispatcher("Home.jsp");
 rs.forward(request, response); 
 }
 else
 {
 RequestDispatcher rs = request.getRequestDispatcher("fail.jsp");
 rs.include(request, response);
 }
</code></pre>

using this it will ask for the credentials at first time login,and it will store the login info in session parameters,if you try to access the site second time it will automatically goes to "Home.jsp" instead of "login.jsp"

please comment whether this method is good practice,any other modifications can be done.
Suggestions are welcome.

I have a <code>login screen</code> and i am authenticating users by checking credentials from database. But how can i implement <code>Remember me check box</code>? Like in gmail <code>remember me(stay signed in)</code> is present. I am using <code>sign.jsp</code> and <code>Auth servlet (doPost)</code> and <code>oracle 10g ee</code> for authentication.

Remember me in jsp login page
