Invalid Request Error with VmwareDistributedVirtualSwitch

[Dominic]

I am trying to get the UUID of a virtual machine, but keep coming up with an invalid request error. Below is my code that I am using. VmwareDistrubutedVirtualSwitch extends DistributedVirtualSwitch, and all of the DistributedVirtualSwitch methods did work for me ( like getName() and getServerConnection() ). But, methods in VmwareDistributed like (getUUID) are not working for me and throwing the error.

Code:

ManagedObjectReference mor = new ManagedObjectReference();

mor.setType( "VirtualMachine" );
mor.set_value( "Test" );

VmwareDistributedVirtualSwitch vd = new VmwareDistributedVirtualSwitch( si.getServerConnection(), mor );

System.out.println( vd.getUuid() );
System.out.println( vms[3].getName() );

Hello Dominic,

InvalidRequest comes into picture when:
either missing some required parameters, or giving inappropriate values.

To get UUID of virtual distributed switch, please use below code.

ManagedEntity[] DVSwitch = new InventoryNavigator(vc.si.getRootFolder()).searchManagedEntities("DistributedVirtualSwitch");
for(ManagedEntity swi : DVSwitch)
{
String name = swi.getName();
if(name.equalsIgnoreCase(dvs)) // dvs is the string form of distributed virtual switch whom u //want to find UUID
{
DistributedVirtualSwitch DVS = (DistributedVirtualSwitch) swi;
UUID = DVS.getUuid();
break;
}
}

PLease revert if need further clarification.

Thanks,
