First, a word of advice: if you have one short Jess statement to
execute from Jess code, by all means use executeCommand(). But if you
have a great deal of code, it's a terrible mess to read, write and
maintain this way -- it makes much more sense to use a batch
file.
On the other hand, there are alternatives to executeCommand() in
Jess's Java API, and again, using the alternatives will generally lead
to cleaner code; in particular, the query-processing loop above, which
just deals with an Iterator and some Java objects, would be much
easier to write natively in Java -- and then the problem of extracting
results goes away, as the results are already in Java! So, for
example,
Iterator it = (Iterator)
jess.executeCommand("(run-query q_problemtypefinal ?w ?y ?z)").
externalAddressValue(null);
while (it.hasNext()) {
Token t = (Token) it.next();
Fact f = t.fact(1);
int prod_ident = f.getSlotValue("prod-ident").intValue(null);
System.out.println("prod-ident: " + prod_ident);
...
}
