Question

I get the session MaxInactiveInterval time using the following query. I am developing web application using JSF Framework

var sessionMaxInactiveTime = ${pageContext.session.maxInactiveInterval};

I need to set maxInactiveInterval.
how to set maxInactiveInterval using JavaScript, JQuery, or to write Servlet.
But i want to control to main template jsp Page.

Is available any links, notes or samples?

Help me. Thanks in advance.

Solution

In doPost or doGet method in your servlet, first get Session object and call setMaxInactiveInterval() method on Session. You can similarly get session object & set max inactive interval (by calling setMaxInactiveInterval() method) from your JSP page.

Below is servlet example:

    // Get the current session object, create one if necessary
    HttpSession session = req.getSession();
    // Set the timeout
    session.setMaxInactiveInterval(2*60*60);  // two hours
