Re: [rules-users] facts comparison
Sure: $p1 : Person(...) $p2 : Person( this == $p1, ... ) this is a special self reference field. You can use any operator, obviously: ==, !=, memberOf, contains, etc, as appropriate.

[rules-users] NPE on DecisionTable rule
Hey, gang!
I have a decision table that generated the following rule:
{other rules removed}
#From row number: 19
rule postponePart_19
when
PoolInfo(courtLocation == 101)
PoolInfo(statusCode = 0, statusCode = 2)
PoolInfo(numberFta 1)
PoolInfo(numberOfDeferralsPosted 2)
PoolInfo(daysBeforeSummons= 2, daysBeforeSummons= 999)
then
answer.setAnswer(true);
end
I call these rules with the following code (I build the ruleBase at the
beginning in the factory method to be used by everything:
StatelessSession session =
participantRuleBase.newStatelessSession();
//now create some test data
PoolInfo pool = part.getActivePool();
BooleanAnswer answer = new BooleanAnswer();
Object[] rules = new Object[]{pool, answer};
session.execute(rules);
return answer.isTrue();
BooleanAnswer is simply a convenience object I created to store the answer
from the rules. (If anyone has a better way to do this, please let me know.)
I got the following stack trace:
java.lang.NullPointerException

you can use something like this. Properties p = new Properties(); p.setProperty(url, your url) ...
