How to rewrite an URL on a JBoss server?

I would like to redirect/rewrite this two kinds of URLs:

• mydomain.com -> newdomain.com
• mydomain.com/specificPage -> newdomain.com/newSpecificPage
• mydomain.com/anyOtherPage -> mydomain.com/anyOtherPage (no redirect here)

So I just want to redirect the root domain to a new domain, and some pages from my domain to some pages on a new domain...

How can I do that on a JBoss server ?
