There's no special trick; you just need to identify the set of rules
that need to be removed, then undefine them one at a time. If you want
to later undefine all the rules defined in an arbitrary CLP file, you
could use a JessEvent listener to watch for DEFRULE events, store the
names of the rules in a list, and then remove the rules named in the
list later.

Hello to all jess users,
I want to apply a set of rules in the Working Memory and later to
delete them.
But I didn't find a way to do this for a set of rules. I found
useful the
unDefRule method but it can be used only for one rule.
The main problem is that when we have a lot of rules (which maybe in
different clp files) it is desirable to apply a set of rules and
later in
different situations to apply a set of some other rules and delete the
first ones. The reset method don't give me the solution because the
rules remain defined so when I tried it all rules
were fired (old and new ones which have true LHS, but this is not my
goal)
Any ideas?
Thanks in advance.
