If I were you, I'd use something like
Global java.lang.Integer cnt;
Rule "before everything"
Salience 10
When
Eval(true)
Then
Cnt=0
End
Rule "condition A"
When
condition A
Then
cnt=cnt+1;
End
Rule "condition B"
When
condition B
Then
cnt=cnt+1;
End
Rule "condition C"
When
condition B
Then
cnt=cnt+1;
End
Rule "action 1, after everything"
Salience -10
When
eval(cnt>=2)
Then
execute action 1
End
Of course, if you change the fact, you'll probably have to think about things
like lock-on-active to increment only one time the cnt variable

Objet : [rules-users] Firing a rule if at least its two conditions are satified
Hello,
we are using Drools in our company. We have a rule with three conditions in
this format:
when
Condition A
Condition B
Condition C
then
execute Action 1
Now we have a situation, in which the rule should fire if AT LEAST two of the
three conditions are satisfied. Do you know how to implement this? Any ideas or
hints?
Many thanks and regards!
skasab2s.
