Business Rule Task

[sandhya_m]

Hi Guys,
Can any one tell why this error is coming when iam trying to run a drl…through a bpnm20.xml

error:
org.activiti.engine.ActivitiException: deployment 20601 doesn't contain any rules

Java code:
              ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
              RepositoryService repositoryService = processEngine.getRepositoryService();
         RuntimeService runtimeService = processEngine.getRuntimeService();
      repositoryService.createDeployment()
      .addClasspathResource("rulesdemo.bpmn20.xml")
      .deploy();
      runtimeService.startProcessInstanceByKey("rulesdemo");


bpnm20.xml:
  <businessRuleTask completionQuantity="1" activiti:rules="demo" id="sid-A917D25A-C3B1-4A83-BB01-FAB530A4CF1E" implementation="other" isForCompensation="false" name="businessRuleTask&#10;" startQuantity="1">

rule:

rule "demo"
when
then
System.out.println("HELLO");
end


Regards,
Sandhya

I have a same problem, I deployed the bar file containing *.drl ! The question here is where *.drl file goes?! How can I find out where it is? And How to solve this problem?

Hi,

The drl is deployed to the Activiti Engine and will be parsed in the Drools engine.
Did you copy the necessary Drools JARs to your classpath?

Thank you for your fast reply!
I have added : drools-compiler-5.3.0.Final.jar , drools-core-5.3.0.Final.jar, knowledge-api-5.3.0.Final.jar ,mvel2-2.1.0.drools4.jar ! By the way, I'm working  with Junit, I'm getting prevous exception deployment * doesn't contain any rules
And I did "almost" whatever you said in this post  > http://forums.activiti.org/en/viewtopic.php?f=6&t=1266&hilit=deployment+doesn%27t+contain+any+rules

The drl is deployed to the Activiti Engine …

Is it in some table in database ?

Hi,

Did you read the business rule chapter (chapter 12) in the Activiti in Action book?
You can look at the source code examples here:

http://code.google.com/p/activitiinaction/

Yes the DRL is stored as part of the deployment resources. You can use the RepositoryService to retrieve all the resource files of a deployment.

I'd love to read but …. Anyway , I'll check Code sample
Thanks
