Note that you could build and assert the facts directly from Java,
combining steps 1 and 2, in about half as many lines of code.
Fact f = new Fact("information", rete);
f.setSlotValue("name", new Value((String) x.elementAt(0), RU.ATOM));
...
rete.assertFact(f);

Indeed, if the ONLY purpose of the family facts is so that you can
then extract the data and pass it back to java, it would be more
sensible to simply pass it back directly.

This is the kind of thing we can easily work out together here.
