v is a variable that holds a reference to a Value object of type
FACT. Here you're asking Java to call toString() on it, and somehow
expecting this string to end up representing a fact in the assert
command; if you think about it, this clearly can't work.
The Jess manual includes two very detailed sections that describe two
exact solutions to what you're trying to do; I don't have a copy handy
but they're both in the "Library" chapter. One is the section on
exchanging values between Jess and Java (about store() and fetch())
and the other is the section about how to assert facts from Java
directly (i.e., without using executeCommand.) Each presents a
different, equally valid solution to your need.
