Vaadin + JBoss 5.1

I am unable to deploy vaadin application on JBoss 5.1 AS server.
Can somenone list steps for the same.

P.S. I even tried deploying vaadin default project using making a .war file by Export option.

It shows Http error 404 - requested resource not found.
But when I keep .html file in contextPath (in war file directly), I am able to access that html file).

Kindly respond, Thanks in advance :slight_smile:
