hello Sir, I have to make a web application in which i have to give session timeout .
means if screen is inactive for a particular period of time then automatically it should
redirect to login page from where user has to login again to access the resources.
I know filters are used for this but do not have the idea .
will you plz give me the example for this task .
will always be gratefull.
Hi ,
You can use filter for same and other option is try to read sessiontimeout from request scope and compare from your maximum session interval.
Right some condtion there and if its is max then session interval , redirect on login page.
First you need to write down the following piece of code in web.xml :
<session-config>
<session-timeout>15</session-timeout>
</session-config>
Here we have set the session time out = 15 minute for the web application.
Now you have to add following piece of code in all the servlets.
HttpSession session = request.getSession(false); //return only the active sessin object
if (session == null)
{
//redirect to login page
}
But this is a long way to implement the functionality.
I will suggest you to use the filter for the same.
cheers
