If I understand your question, remember the servlet runs on the server box.
You can't get to the client's console. You can only get to the client's browser.
I think what you want to do is show process status while servlet is running.
You can do this but you need to implement a redirect methodology.
Please check the archive. Archives:

The redirect subject has been discussed many
times in the past. You should be able to glean information.
Sans adieu,
