drl file location

[rhiremat]

Hello Folks,

I am new to activiti as well as drools and we are evaluating the tool as an orchestration engine for one of our products.
After some struggle today I could deploy the activiti jars and in activiti-explorer\WEB-INF\lib and my ServiceTask and POJO class deployed in ctiviti-explorer\WEB-INF\classes.


Here is the code snip :

try {
            // load up the knowledge base
           KieServices ks = KieServices.Factory.get();
               KieContainer kContainer = ks.getKieClasspathContainer();
           KieSession kSession = kContainer.newKieSession("ksession-rules");
           
           ApporveReject approveReject = new ApporveReject();
           approveReject.setStatus(0);
           kSession.insert(approveReject);
           kSession.fireAllRules();
           
    }catch (Throwable t) {
            t.printStackTrace();
        }
      
Now, it seems that the drl file is not to be found. Check below :

04:49:43,078 [http-8080-1] INFO  org.drools.compiler.kie.builder.impl.ClasspathKieProject  - Found kmodule: file:/C:/Program%20Files/Apache%20Software%20Foundation/Tomcat6.0/webapps/activiti-explorer/WEB-INF/classes/META-INF/kmodule.xml

I have tried putting my drl file in following locations without success, any suggestions, pls?

activiti-explorer\WEB-INF\classes
activiti-explorer\WEB-INF\lib
activiti-explorer\WEB-INF\classes\mypkg\

Appreciate any help on this.

Hi,

It seems more like drools question from my point of view.
Did you try drools support in the activiti?

Thanks for the reply Martin,

I could resolve this by putting the rule under proper package in the classpath.

Side Question - activiti supports drool - What do we mean by that?
What is OOB provided in activiti for that?

Well, see http://activiti.org/userguide/index.html#bpmnBusinessRuleTask

Basically you can put drools rules together with your process and those will be handled by the drools engine.

Thank you for continued feedback on this.

I am able to create a service task and call drools rules and pass parameters to drools and get them back.
I am still not able to get the feel of Business Rule task - the documentation is good, but not in this case.

Is drools workbench UI like editor available in activiti UI OR the two are essentially separated?
Does activiti carry drools engine run time?

Sorry for bugging all, but I need to clear this up, I think I understand activiti and drools separately,
need to understand better integration (I do understand their integration from use case preservative but not technical know how aspects here).

Hi Raj,

I think that the best example how the integration is implemented could be to follow jUnit test and it's spring configuration.
