BusinessRuleTask question

[user8p]

Hi,

I was hoping to plug in external rules engine using the way I read in Activiti user guide -
if you want to plug in your implementation of the rule task, e.g. because you want to use Drools differently or you want to use a completly different rule engine, then you can use the class or expression attribute on the BusinessRuleTask and it will behave exactly like a ServiceTask

However with as simple implementation as below, I am getting org.activiti.engine.ActivitiException: deployment 5 doesn't contain any rules error -

<businessRuleTask id="businessRuleTask" activiti:class="${MyRuleServiceDelegate}" />
‍‍‍

Stacktrace -
org.activiti.engine.ActivitiException: deployment 5 doesn't contain any rules
org.activiti.engine.impl.rules.RulesHelper.findKnowledgeBaseByDeploymentId(RulesHelper.java:51)
org.activiti.engine.impl.bpmn.behavior.BusinessRuleTaskActivityBehavior.execute(BusinessRuleTaskActivityBehavior.java:48)

I looked at the classes in stack-trace (RulesHelper.java and BusinessRuleTaskActivityBehavior.java),  activiti process engine still tries to find KnowledgeBase. Is this expected when we are trying use an external drools engine? Please advise.

Which version of Activiti are you using? Because in Activiti 5.14 this usage of the business rule task is not supported anymore. You can use a service task to implement your custom rule execution logic instead of using a business rule task.

Hi,
I am not sure whether this issue is connected to business rules.
It seems more like a problem not connected with activiti. I did not find any org.activiti.* package in the stacktrace. (Resource bundle not found).
