The initial request starts a thread running and puts a reference to the thread, or to some proxy for the thread, into the user's session.
Subsequent requests get the thread from the session. If it is still alive, the response says "Still running", otherwise the response says "Finished".
Of course you can expand on this basic structure to return the result of the long-running process, or to return the percentage complete if the long-running process can produce that information.

it is not possible to get the view from the servlet in the middle of the execution and once again go back to the execution point, all container generates the view after complete execution of the servlet.
