You're constructing the fact incorrectly. The first argument to Fact's
contstructor is just the "head" or name of the fact -- in your case,
"R." The slot data has to be added after the construction. See manual
section 4.7. To construct an ordered fact, note that you put the data
into the slot named __data as an RU.LIST:
Fact f = new Fact("R", r);
ValueVector slot = new ValueVector();
slot.add(new Value("e", RU.ATOM));
slot.add(new Value("w", RU.ATOM));
slot.add(new Value("q", RU.ATOM));
f.setSlotValue("__data", new Value(slot, RU.LIST));
