you can set that in web.xml inside your web application.
Is there a way to set it globally? Can it be set in the standalone.xml/domain.xml? Is there a global web.xml that wars inherit from, like in most other containers?
We'd like to allow our users to set this and we discourage them from touching the war.
I am not aware of any way of doing this globally anymore (disclaimer: doesn't mean there isn't one)
