Advice on primefaces ajax and long running task

[obinna]

hi, there is a part of my application with a procedure that takes about 20-35mins to complete. i am developing this application with primefaces 2.2-final.
if i call this procedure via ajax through a p:commandbutton, will the session not time-out?
because of this concern of session timing out, i am currently developing a desktop app for only this activity of the application.
but if the session would still be active for that long while the ajax request is going on?, i would really love to use a web front-end for that part of the
entire application.

what do you think, i really need some advice?

thanks

I'd assign this to another thread in your application. For example spring has thread pooling so you separate that task from the web request.

hi optimus, thanks, but i think i will prefer quartz scheduler framework than spring, cos m not so used to spring. then i can modify the procedure to update some table with the progress of the procedure (Running, Completed Normal, Completed With Erros, etc ) , then using primefaces ajax poll i can then check this table periodically and display the status on the page.

is this idea okay?
