Enabling server-side includes (ssi) on

I am using the JBoss application server (really JBoss-SOA) 5.2 to run a development web project. I'm deploying a static web project, no web.xml, etc.

Two questions:

1. How do I enable sever-side includes? I have tried using includes with .shtml but the server is not processing them.

2. How do I modify the welcome file list so that index.shtml is recognized as a welcome file? (again, not using a web-xml)
