This section of the manual has both a jess and java version of iterating through the query results - scroll down a bit, if necessary, to see the java code.

Subject: JESS: Very simple defquery question
I have batch file as follow:
(deftemplate lesson
(slot ordinalNumber (type INTEGER))
(slot ID (type INTEGER))
(slot difficultyLevel (type INTEGER))
(slot belongs-to-concept (type INTEGER)))
(defquery find-lessons
(declare (variables ?currConc ?diffLevel))
(lesson (difficultyLevel ?p&: (eq ?p ?diffLevel)) ( belongs-to-concept ?s&: (eq ?s ?currConc))))
and I need to run query from Java and read values of lesson's slots for all choosen lessons. I have tried to write something like this:
public void runQueryFindLessons(int currConc, int diffLev) {
try {
ValueVector vv = new ValueVector();
vv.add(new Value(currConc, RU.INTEGER));
vv.add(new Value(diffLev, RU.INTEGER));
Iterator it = engine.runQuery("find-lessons", vv);
System.out.println("Funkcija runQueryFindLessons klase DiscoursePlanner");
try {
while (it.hasNext()) {
System.out.println(" in this part I need to read lesson slots");
}
} catch (NoSuchElementException ex) {
}
}
catch (JessException je) {
}
}
