We are in the process of automating end-to-end scenarios wherein different system components are involved. The initial steps are to be done in a VRU component and the client prefers to perform these steps using Hammer from empirix. The other remaining steps are proposed to be performed using QTP and the entire test execution has to be done / controlled using Test Director. Regarding these, we need certain inputs regarding design

-- Is it possible to call Hammer scripts from QTP scripts ? If yes, then what is the recommended approach.
-- If in case it is not possible to call Hammer from QTP, then is it possible to invoke Hammer scripts from Test Director directly using open test architecture API of TD.
