[rules-users] Using Rule Flow

[Natraj Gudla]

Hi,

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.

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
