How to force an URL scan of the DeploymentScanner in EAP 5?

Issue

We are trying to force an URL scan of the DeploymentScanner in EAP 5 using twiddle, as we have done previously in EAP 4.3, but this command throws an exception. I guess in jboss 5 there is a new mbean. What is the Mbean to invoke in Jboss 5 in order to force an URL scan?

./twiddle.sh -u user -p password invoke jboss.deployment:type=DeploymentScanner,flavor=URL scan
13:56:20,028 ERROR [Twiddle] Command failure
org.jboss.console.twiddle.command.CommandException: MBean has no such operation named 'scan' with signature compatible with: []
