Hi,
In JSP you can set the time as:
session.setMaxInactiveInterval(seconds);
After the specified seconds session will be expired automatically if no request has been made..
Thanks and regards,

I found the following in Tomcat's base web.xml file in the Tomcat-home/conf/ directory

 
  <!-- You can set the default session timeout (in minutes) for all newly   -->
  <!-- created sessions by modifying the value below.                       -->
<session-config>
    <session-timeout>30</session-timeout>
  </session-config>
 

30 minutes seems to be a commonly used number.

In the HTTP protocol, there is no explicit termination signal when a client is no
longer active. This means that the only mechanism that can be used to indicate when a client is no longer active is a timeout period.
The default timeout period for sessions is defined by the servlet container and can be obtained via the getMaxInactiveInterval method of the HttpSession interface. This timeout can be changed by the Developer using the setMaxInactiveInterval method of the HttpSession interface. The timeout periods used by these methods are defined in seconds. By definition, if the timeout period for a session is set to -1, the session will never expire.

But the default is server-dependent.
