[jboss-as7-dev] how to increase session timeout for application deployed on jboss as 7.1.1

Hi, I have not set any <session-timeout> in my application. It is set only to default I guess and after some 1 hour or less time it expires. I tried to set it into web.xml of my application but it does not work for me. Here I request you to please guide me how can I set a session timeout to any specified time in my application. My understanding is that whatever be the session timeout would be set in any server configuration file, web.xml of the application is the file that finally override all configuration and set the time put in its <session-timeout> tag, as in the below example it shall set a session timeout of 2 minutes. <session-config> <session-timeout>2</session-timeout> </session-config> But it is not working in my case, it still remains about 1 hour. Looking forward, Rishi
