RiftSaw on JBoss AS 7 is part of the SwitchYard project (http://www.jboss.org/switchyard/) which is basically the new ESB.
Here's a guide how to use BPEL: https://docs.jboss.org/author/display/SWITCHYARD/User+Guide#UserGuide-BPELServices.
I hope this helps.
I see. That confirms what I thought and gives a path to the solution.
