[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

Hi,

You have to add the Drools drl or equivalent file as well to the deployment.

Firstly thanks for ur reply..

i have used

rules.drl in my deployment

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

The thing is ,im calling the rules from my bpnm file(activi:rules="demo")but its nt wrkng (error is generating)
So, how can i call it from my bpnm file /java file so that my rule will execute successfully

Hi,

You say you have the following Java code:

ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
RepositoryService repositoryService = processEngine.getRepositoryService();
RuntimeService runtimeService = processEngine.getRuntimeService();
repositoryService.createDeployment()
  .addClasspathResource("rulesdemo.bpmn20.xml")
  .deploy();
runtimeService.startProcessInstanceByKey("rulesdemo");
Just add an additional

.addClasspathResource("rules.drl")
to the createDeployment statement.

Best regards,

Hi,

You have to deploy the drl-file (the way you do) BEFORE you start the process using processService. Just adjust the order of your code-lines…

It should be in ONE deployment, not two
RepositoryService repositoryService = processEngine.getRepositoryService();
RuntimeService runtimeService = processEngine.getRuntimeService();
repositoryService.createDeployment()
.addClasspathResource("rulesdemo.bpmn20.xml")
.addClasspathResource("rules.drl")
.deploy();
