JBoss AS 7 with two webapps on different http ports?

To replace a legacy service I am interested in having two different webapps on two different HTTP port numbers, e.g., 8080 -> webapp1 (browser service), 8200 -> webapp2 (REST, new version uses RESTEasy). Each will be the "root context" on that port number.

The "standard" answer on this site relates to JBoss 5, which is two major versions back in history and has a zillion configuration format changes.

I'm using JBoss AS 7.0.2.Final and the "standalone" deployment. Anybody done this and can share the configuration used? Thanks.
