If you point JBoss to a folder like "file://c:/.../test.war" to deploy a web application, then the web services in this web app are not deployed and there is a ClassCastException, complaining the servlet class is not a servlet.

In my jboss-service.xml file:

<attribute name="URLs">
deploy/,file:/c:/Dev/DevRoot/fcd-web-console/src/WebRoot.war
</attribute>

The web application works using this deployment, except for the web services.
