How to set a process to use drl rule just by using the drools-guvnor, web editor, and jbpm console?

[thomas.setiabudi]

Hi,

I am using JBPM5.3 Full installer.

Is it possible to create a process with a Business Process Task node that execute a drools rule (drl) without using the eclipse but just by using the drools-guvnor, web editor, and jbpm console?

I refer to a discussion here:

https://community.jboss.org/thread/167350

It says we have to execute this script on a node prior to executing any rule

kcontext.getKnowledgeRuntime().insert(kcontext.getProcessInstance());

then on the rule itself looks to be something like this:

import com.sample.User;

import org.drools.runtime.process.WorkflowProcessInstance

rule "AgeCheck3"

ruleflow-group "AgeCheck"

    when

        processInstance : WorkflowProcessInstance()

        age: Integer() from (Integer)((WorkflowProcessInstance)processInstance).getVariable("Age");

        eval(age < 18);

    then

        processInstance.setVariable("Name", new String("Denied"));

        System.out.println(age);

end

The problem is I cannot figure out on how to specify import when I create a rule via drools guvnor. Is it even possible?

And how do we trigger the fireAllRules or fireUntilHalt if we are not using eclipse?

Any help is appreciated.

Best Regards,

Seems like I have to create a Technical Rule (DRL) inside the drools-guvnor,

by doing it this way, i can specify my import line.

And I manage to get my rule works without calling fireAllRules, maybe this is caused by my architecture where I use JBPM as service by managing the process via jbpm-console REST service instead of embedding the JBPM engine in my own application.

my test rule that finally works looks like this:

import org.drools.runtime.process.WorkflowProcessInstance

rule "AlterName"
ruleflow-group "ChangeName"

when
processInstance : WorkflowProcessInstance()
eval(1 < 18);
then
processInstance.setVariable("name", "NewName");
end
