<div>Hi,</div>
<div> </div>
<div>Has any one used Rule FLow with 4.0.0. I am looking for some help on how to use rule flow, where to mention the drl file name. How to use it in the java invoker classes.</div>
<div> </div>
<div>I have tried something, created a TestRuleFlow.rf, then added a rule group, gave it a group name as drl file name. When i use the PackageBuilder to add the rule flow, it throws the following exception </div>
<div> </div>
