Hi again.
First of all, I'm running Drools 5.1.0.SNAPSHOT on Windows and Eclipse 3.4.
I've submitted a Jira Issue (
https://jira.jboss.org/jira/browse/JBRULES-2511):
"
I've got a system that receives transactions. I want to implement the following rules:
- raise an alarm(alarm event) when there aren't any transaction for an hour (or more);
- if there's an alarm, no more alarms should be raised;
- if there's an alarm and the system receives a transaction, that alarm should be
retracted and the system should send an recovery event.
I've implemented the rules this way:
- ***start*** rule to insert an "EngineStart" event when the rules engine starts
- ***notrx_after_start*** rule to detect absence of transactions during the first hour
- ***notrx_after_trx*** rule to detect absence of transactions (during one hour) after
last transaction
- ***rearm*** rule to detect transactions and rearm the system.
I made a Maven project with junits, which inserts transactions at specific time, in order
to raise the desired events.
Two set of tests were made:
- the rules defined in "default" entry-point: the correspondent junit gives a
NullPointerException in DefaultAgenda
- the rules defined in "incoming" entry-point: the correspondent junit
doesn't activate the ***rearm*** rule
"
The issue has an attachment with junits and rules to play with.
T.I.A.
