Connecting to BSA from VRO

Hi,

I'm trying to connect BMC Bladelogic server automation tool from VRO(6.0.1). I need to execute a NSH script job on BSA triggering it from VRO. BSA is installed in a LINUX machine. is there any option to connect it from VRO other than using web services? what are all the available options?

Thanks,

Mano
