Session expires even doing operations on pop up Window (Window.open)

On our Application , We have HyPer Links on our Grid .(Result Display) On click of that a new Pop Up Window is opened , using 开发者_如何学Gowindow.open pop up mechanism We can do several operations on that newly opened window like Insertion , Deletion ,Updation of data with respect to DataBase .

The issue is that , even though we are doing several operations on our Database , the session is being expired on to the Application .

Please tell me how to resolve this issue ??

Not easy to provide an answer. It highly depends on your environment. Maybe your application server does not only rely on JSESSIONID, it may use cookies provided by a certain SingleSignOn system. Those cookies may have a fixed lifetime. Trace your HTTP requests / responses using Firefox Firebug or WebKit (Chrome) developer tools and check which cookies are exchanged. If necessary define a javax.servlet.http.HttpSessionListener and track the application server's behaviour.
