color:#1F497D'>I've got a system that receives transactions. I want to
implement the following rules: <br>
- raise an alarm(alarm event) when there aren't any transaction for an hour (or
more); <br>
- if there's an alarm, no more alarms should be raised; <br>
- if there's an alarm and the system receives a transaction, that alarm should
be retracted and the system should send an recovery event. <br>
<br>
I've implemented the rules this way: <br>
- ***start*** rule to insert an &quot;EngineStart&quot; event when the rules
engine starts <br>
- ***notrx_after_start*** rule to detect absence of transactions during the
first hour <br>
- ***notrx_after_trx*** rule to detect absence of transactions (during one
hour) after last transaction <br>
- ***rearm*** rule to detect transactions and rearm the system. <br>
<br>
I made a Maven project with junits, which inserts transactions at specific
time, in order to raise the desired events. <br>
<br>
Two set of tests were made: <br>
- the rules defined in &quot;default&quot; entry-point: the correspondent junit
gives a NullPointerException in DefaultAgenda <br>
- the rules defined in &quot;incoming&quot; entry-point: the correspondent
junit doesn't activate the ***rearm*** rule<o:p></o:p></span></p>
