@Benjamin:
Esteban just confirms what I was trying to explain in my previous answer.
Ruleflow decisions aren't made on a per-fact basis - all facts in
Working Memory participate in their evaluation.

If the entirety of what you're making a decision on can be expressed in a
handful of facts then it may be reasonable to use a stateless session, as
you will need to insert them for every request.

As for the function, there's a minor known bug. The packagebuilder is

Drools Flow (aka JBPM5) will look for all the Persons and Dogs you have in

Since the conditions in an XOR gateway are evaluated in order, the first
one being true is going to be selected.
In your case, after you insert the Persons, both rules are activated, but

I would say to have a Map where the keys are "AndroGel",

that apply to that particular product.

Instead of grouping your rules using agenda-group maybe you could partition
your kbase to only have the rules for a particular Product (?)

Add a fact User with field group, set appropriately, and extend the

I don't think that using agenda groups would be a good approach.

I have a requirement which says that only few rules should be fired based on
the user group. How am I suppose to do that.
Only thing I think of is that I have to setFocus in the rules on either
Agenda-group or Activation-group.
please let me know.
Thanks.

Ok, for my rule files, the facts for all the rules are same. That is the

So can a rule have multiple agenda Group, something like this.

or

I mean to say is that, control does not come back to
workingMemory.fireUntillHalt(). It just hangs in the rule file itself. Does
not do anything at all.
What is the use of that.
If I write like halt in the rule then it should stop the rule firing and
control should be sent back to workingMemory.f
In the simplest case, just add the drl files as classpath resources.
For example:
src/main/resources/org/domain/myRules.drl
get copied to
target/classes/org/domain/myRules.drl
get copied to
target/myWar.war!WEB-INF/classes/org/domain/myRules.drl

Hi all,
We are using rules in our java based project that connects to jboss for jms.
To implement rules, we include drools specific jar files in the code itself.
When this code is executed, rules also get executed and our purpose is
