We have an application with struts frame work.In which we have used JSP, EJB's and the application session out we have kept it as 30 mins.
We got a requirement like below :
For Example the student was filling an college form which contains some 5 JSP'S to fill the details and the student has filled 3JSP's and he was doing some other work and when he come backs after 45 mins to enter the details the session got expired. The requirement was after 25mins it should pop up a message in the screen "the application session is going to expire in 5 min" (as a remainder). I have no idea how to do proceed. Can you guys please help me on this.
