Hi,

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

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();

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?

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.
