Hi,
looking at the process order example in Drools 5.0 I wonder what
workflow_rules.drl is doing? It relies on implementation details but seems not
to be used on execution.
thanks,

What error? Can you paste the server log?
Maybe it's the white space before 'brms' in your connection url? Maybe
you didn't provide the driver jar?
Cheers,

You have not clearly defined when you want to execute SQL queries.
If you want to access a DB from the LHS you can use the from keyword.
Note the results need to be time-constant i.e. not change on successive
calls.
If you want to access a DB from the RHS it is plain Java (or MVEL

Did you replace the EL jar with that available from JBOSS?
You will still need an EL jar somewhere if you are using JSF.
Do you have Java security enabled in your Tomcat instance? I've
previously had to put the EL jar in Tomcat's lib folder to fix other

You want the user to be able to define the SQL query (table, field list,

thought a rules engine might not be your best option.
The best I think you could achieve would be something like this...

$t : Tables(query == $q)
$p : Predicates(query == $q)
then
es.execute($f, $t, $p);

Yes ruleflow support wait state in the same way that jBPM does. With a
different approach maybe, but you can do exactly the same with Ruleflow.
There is also a limited support for jPDL inside ruleflow, that means, that

Not sure I understand your question. Does not matter if your rules are in

Let me try to answer the first set of questions:

can I call long-running services from it asynchronously?
Of course, there are various nodes that behave as some sort of wait

Your requirement isn't that clear however here's a few thoughts:-
Data can be inserted into the Rule Engine either externally (i.e.
WorkingMemory.insert) or internally (using from).
If you use DSL you can make DRL more human readable; although neither

Hi Michal,

if you are able to create your packages, then you do not need the guvnor,

The order example can be executed using what we call advanced execution
