JESS: Retrieving slot and multislot values

/* I need to retrieve slot and multislot values. */

Value v1 = fact.getSlotValue(slotName).toString());
/* Assuming above is ok */
Value v2 =  fact.getSlotValue(multiSlotName);
ValueVector vv = v2.listValue(context);

where or how do I construct an appropriate "context"?

Do I need to do this for v1 also or is toString() good enough?
