I have a same problem. My exploded war resides outside jboss's deploy directory and is linked to be deployed in jboss-service.xml
<mbean code="org.jboss.deployment.scanner.URLDeploymentScanner" name="jboss.deployment:type=DeploymentScanner,flavor=URL"> ... <attribute name="URLs"> deploy/,file:/ws/default/SCB_US/Engineering/selenium-test.war </attribute>
I have tried also to put / character at the end (.../selenium-test.war/). Exception disappeared, but war was not deployed.
mailinator, you should have created a new post, not appended to an existing one.
But to answer your question, set URLs to:
The key is that any URLs entry ending in '/' is trated as a direcotry and that directory is scanned for things to deploy (both files and exploded directories). Anything that does not end in a '/' must be a file, which means that the war would have to be packaged.
