Hi All,

Can we restrict the number of user logging an application from Web.xml

The Servlet specification makes no provisions for this, so you'll have to implement it yourself. It sounds pretty easy to do.

Take a look at servlet listeners to see when sessions are created/destroyed. Note that if people close the browser without logging out, you won't know until the session times out.
