  - setInvokingTrail

public static void setInvokingTrail(Trail trail)
```
    Provides set access to the InvokingTrail. Normally this should not need to be invoked by service or RA code.
    
    In some rare cases, where interacting with not yet SAS enabled code it may be necessary to manually set a real trail, as the code creating the activity has not attached a trail.
    
    Parameters:
    
    trail - to set as the invoking trail
  - remove
```
public static void remove()
```
    Removes the trail object from the current Thread. After the call to remove, the NULL_TRAIL will be returned by subsequent gets This is called internally by Rhino, and should never need to be called by deployed code.
