You could create a root context with a page that redirects to your designated area.
You could also have a front-end Apache with URL rewriting to achieve the same result.
However, normally I would guess that you would move your whole application to the root context. See the FAQ for JBoss 3.2.0 changes for information on mapping web applications to the root context.
I have maked a small war with one page index.html that's run as root context and does a redirect
anyway thanks for the tips
