I would like You to ask what is the best way to download the file from server (Rest Spring Service) to the GWT Client?
As far I know I can use 2 options:
Window.open(have tested)iframe(haven't tested)
For Rest asynchronous ajax calls I use RestyGWT, but I did not find a word about it.
I've tried Window.open, it worked, but when my session expires it didn't redirect to login page.
Please help.
