How to get a ManagedObject from ManagedObjectReference

I am using vijava.  I have MOR object.  How do I get HostSystem for example from the MOR?


I was hoping using the following will work:

HostSystem hs = (HostSystem) new InventoryNavigator(si.getRootFolder()).searchManagedEntity("HostSystem", mor.getVal());

where "mor" is the ManagedObjectReference of the HostSystem.

Thanks in advance
