Hi, I have written some rules and now I want to write rule-flow. But there
are few questions.
1. I have written some rules of validation, where if not having values, they
will throw exceptions, in the flow the exception is a different task, so
should I write the rule file for these errors?
2. Also one of the rule in the rule file is a separate task in the
rule-flow. How can I do that.
Please help me on this.
Thanks,
Venkat.

Hmm I saw in a lot of customers that they are trying to write some
validation rules and they want to enforce the rules evaluation using
ruleflow-groups. If that's your case I suggest you to reevaluate your
scenario. Using ruleflow-groups you will not prevent the evaluations
of the rules, you will only enable the rules to fire when they reach
the RuleTask inside your process.
You can have multiple rules file with different rules in different
ruleflow-groups, there is no limitation about that.
Cheers

Thanks for your reply, but the problem I am facing is
The rule file that I wrote, has some rules which are divided into two
ruleflow-groups, but one of the ruleflow-group should be done inbetween the
other ruleflow-group and this is a separate task in the rule flow.
And I don't know how to do that.
Thanks,
Venkat.

If you have two RuleTasks and two ruleflow-groups you should only make
a reference from the ruleTask to the ruleflow-group that you want.
Look at the properties panel clicking in the ruleTask node. But once
again, the evaluations of all the rules will happen at the same time
when you insert information into the session, and not when your
process hits the RuleTasks nodes.
Cheers

I have seen your last point you told, now I see, but I have a question now.
If you say so, what is the Rule Flow do. I have read about it and it says
that is a engine that will process the flow.
right?
Thanks,
Venkat.

you can take a look at the official documentation here in www.jbpm.org
-> documentation:
http://docs.jboss.org/jbpm/v5.2/userguide/ch05.html#d0e1350
The documentation is in some way wrong, because the evaluation happens
when you insert information in the knowledge session.
The rule flow or business processes allows you define a set of
interactions between systems, rules and people working together to
achieve a business goal. You can build very complex interactions using
the business process metaphor. It's not just a way of evaluating and
executing rules.
If you want to evaluate two sets of rules in different moments you can
use a control fact that needs to be filtered by one these sets or you
can have two different sessions with different set of rules in each of
them.
Cheers

Thanks for the link, it is helpful.
This flow is not just about the validation, it is that starting point of the
flow. We are just starting to use this technology and we want to see how it
works for us.
is there anyway that we can call the java class directly or is it only the
rules that we have to write?
Thanks,
Venkat.

You can call external systems using the concept of work items, check
the official documentation in the section: Domain Specific Activities
