In the Apache ODE project, the HTTP binding is provided by the Axis2 integration layer.
RiftSaw uses jbossws for its integration, supporting jbossws-native and cxf web service stacks. jbossws does not provide REST support.
In terms of the JBoss software stack, we have the RESTeasy project to provide REST support - but currently we don't have integration between RESTeasy and RiftSaw. Therefore it may be best to raise a feature request in the riftsaw jira.
