how to pass vm as input param to execute workflow

Hi,

i am trying to execute an workflow through webservices development API for vCenter Orchestrator.

could you please advise me how can i pass a virtualy machine of typ VC:VirtualMachine as an input param through API.

right now i am doing it in this way and its giving error on workflow side "invalid vm parameter"

please advise

FinderResult finderResult =

vmo.findForId("VC:VirtualMachine", "aspvc.ap.vspp/vm-199",username, password);

WorkflowTokenAttribute[] inputParameters =

new WorkflowTokenAttribute[workflow.getInParameters().length];

// in our workflow, we only have one parameter.

inputParameters[0] =

new WorkflowTokenAttribute();

inputParameters[0].setName(workflow.getInParameters()[0].getName());

inputParameters[0].setType(workflow.getInParameters()[0].getType());

// and put our serialized Virtual Machines values

// #{#finderResult.getType() +#+finderResult.getDunesUri()+#}#

inputParameters[0].setValue("

#{#VC:VirtualMachine#dunes://service.dunes.ch/CustomSDKObject?id='aspvc.ap.vspp/vm-199'&dunesName='VC:VirtualMachine'#}#")

// Now, start the workflow. Here, we don't need to wait the workflow ends

, inputParameters);
