unable to execute rule engine

trivedi

Hi All,

I have been trying to integrate Activiti with Drools, followed the approach what has been described in sample applications. But I couldn't get succeed, the rule is supposed to be fired for my test case, which is not happening. Can someone have quick glance and help me on this? I have spent almost a day on this.

Thanks,
Trivedi

Hi,

I've tried to run your unittest (testDroolsPath) and it runs fine, console output:

Hi ,

The test case runs well without any errors. But, it is supposed to execute the rule file, which is not happening. Just in case if it executes, then flow should end up with "MMA Referral Task" instead it is going to "Reject Document" node. One thing for sure is that the rule is not getting fired .

Thanks,
Trivedi

Hi,

Aha, normally unit-tests we get fail to show what's wrong

I see the rules-deployer kicking in, so the rules are picked up and the rule is present in the KnowledgeBase… But I think you should specify a rules-input if I'm not mistaken, you can't just use the variables of the executions by name.

trivedi

I don't think unit tests are capable of giving enough details about what is going wrong here. Is there a way i can increase the log level and see if something comes out? Also could you please elaborate on "specifying rules-input", I couldn't followed you that suggestion. I am a beginner in working on BPM tools.

Thanks,
Trivedi

A unit-test could at least show me what output should be (like you said in the post after "flow should end up with "MMA Referral Task").

Everything you use in your in your business-rule task should be passed as input-variable (eg. order):
<br><businessRuleTask id="ruleTask" activiti:ruleVariablesInput="${order}" activiti:resultVariable="rulesOutput"/><br>

<br>package org.activiti.rules.deploytest;<br> <br>import org.activiti.standalone.rules.Order<br> <br>rule "OrderItemCountZeroOrLess"<br>&nbsp;&nbsp;&nbsp;&nbsp; when<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; order : Order( itemCount <= 0)<br>&nbsp;&nbsp;&nbsp;&nbsp; then<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; order.setValid(false);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>end<br> <br>rule "OrderItemCountGreaterThanZero"<br>&nbsp;&nbsp;&nbsp;&nbsp; when<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; order : Order( itemCount > 0)<br>&nbsp;&nbsp;&nbsp;&nbsp; then<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; order.setValid(true);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <br>end<br>

I really appreciate for your quick responses here. However, I tried your option in my example, it didn't worked. Were you able to get it working in sample that I attached? if so, please upload that sample that would helps me.

Thanks,
Trivedi

Hi,

Could someone help me on this? or provide me some guidance on this?

Hi,

Just change the businessRuleTask definition to:

<businessRuleTask id="businessruletask1" name="Eligible Service" activiti:ruleVariablesInput="${patientDto}"></businessRuleTask>

Then the rules are executed.

Best regards,
