yes.. sounds more like a normal java problem than Drools FLow problem. I
think that your solution is the correct one because it handle internally the
multithreaded requierements and then it continue the business process
normally.

Hi guys,
I am trying to implement multiple timers in a single ruleflow.
I am trying to achieve:
1. Multiple timers running at the same time.
2. Multiple timers running consecutively.
It seems to me that the current implementation will not allow for this kind
of behavior out of the box.
ideas?

Is there documentation on how to do this, including a full example. I saw
the pom file, but still don't know the run/compile targets?

Hi,
just starting using drools and need to use templates but having error
messages (described in comments in the code below).
I checked the meaning of the error messages but still can't figure it out.
I modified an simple rule according to the template section of the drools
manual: btw I use the e
I have a set of externally defined java beans that are utilized elsewhere in
the overarching application, and would like to declare these external
classes as events within drools. I am able declare these objects as events,
and compile a drools DRL file, and execute the rules. When the same DRL is
The idea is to run multiple independent sub flows. Each of the sub flows
requires approximately 2 minutes to complete, so parallel processing is
required. Once all the sub flows have completed their tasks is necessary to
collect all the results and process them. This implies that the workflow

Hi all,
I need to perform a test in the Drools Rule Engine. This test is intended to
discover the SLA for Rule Processing.
The scenario that I have is:
- My Knowledge Database will have almost 200 million records.
- There will be a full monthly charge and a short diary charge in this KD.
- T
Looks like an NPE in your rule.
Maybe maintenanceSlot or something is null.
You should raise an issue with drools-core (drools expert) that it
should give a better runtime error to show on which line it NPE'ed.
With kind regards,

I have everything exactly the same as you (just like in the documentation),
the only difference being the SQL for fetching the tasks. You will notice
that mine has two inner joins, and yours hasn't.
H, that makes me think, could it be something involving

Can you provide an isolated test case to reproduce this problem? If so,
please create a JIRA, attach your case and ping me plz.

Hi Bertrand,
Did you see my blog posts about Drools Grid? during this weekend I will post
one presentation that I've do in Drools Boot Camp in San Diego yesterday,
where I discuss this topic for large environments.
In the meantime you can take a look at my previous blog post about this
work:

I'm not sure if can be done right now... but it's a cool feature to add..
we are also thinking to add support for a flow based revision of each rule..
that allows the user define a set of stages required to a rule to be usable
and exported.

I'm not sure about what you want to achieve.

client.getTasksAssignedAsPotentialOwner("Joe", "en-UK", summaryHandler);
This method used the "en-UK" for i18n reasons.. you need to set the field
content (and I'm sure right now, because that I don't have the source code
here) and the field comment to "en-UK".

Have you ever thought of using maven? Your problem is no doubt with including
the transitive dependencies of the drools libraries, which maven would do for
you automatically. Here are the jars that were included automatically in a

I use drools guvnor first version 5.1.0, but now I have to use 5.0.1.

Did you see the "en-UK" parameter in the getTasksASPotentialOwner method?
are you setting that value to the content field?

As ever the answer is it depends on how you want to do it and where you want to
put the logic. I'm not convinced that necessarily need to use flow, instead
just use a stateful knowledge session (one per client session).
