yes, scanning for updates is possible in SwitchYard. You can achieve that by:
<rules:container releaseId="org.acme:myartifact:1.0-SNAPSHOT" scan="true" scanInterval="10000" sessionName="my-session"/>
in your rules component declaration in the switchyard.xml. You can configure that by the tooling: Implementation -> Resources -> Knowledge Container.
Thanks! That's exactly what I'm looking for.
