Take a look at the VRP example too: it's basically the TSP example, but with
multiple vehicles.
1) It depends, but I would add a hard constraint for this. Once 5.5.0.Final
is out, you might use move Filtering instead, so it doesn't even evaluate
those solutions (but that also blocks it from

A numeric comparison of the the event timestamps did the trick.
Now I am wondering, whether using simple arithmetic operators

I designed process in drools with human tasks included, add the variables,

Hello,
I'm trying to upgrade from 5.3 to 5.4 and i guess i must have configured 5.3
to not authenticate when accessing the resources in guvnor like the
binaries, etc using the REST api because when i try to access them under 5.4
i'm getting the 401 response.
I read that security is configured in
The issue seems to be your assignment mapping of the task data outputs.
Please note the To and From columns in the data assignments editor:
** When you are mapping DATA INPUTS:
From columns should have the object you are mapping from, so like
process variables, globals, etc

Thanks,
Actually I followed the pattern of assigning variables -- input and
variables -- output.
But, it is clear i.e. variables -- input and output -- variables.
Last question, when I build the package in drools, everything is Ok. But it

Hi all,
I've run into a memory issue when using Drools, and I was hoping someone
could help out.
I have a project that uses StatefulKnowledgeSession's, and every couple of
weeks I get OutOfMemory from the JVM. I've done heap dumps and analyzed the
dominator_tree, etc. No luck yet in

I am creating a web service in java using eclipse and axis2 which has some

Look at your server logs when you first click on the Processes tab in
console after a server start...this should give you some indication of
what could have went wrong.
If you have any fact models uploaded into Guvnor (like .jar files),
console is not able to look them up, so you need to also

Dear Tihomir,
Your reply is always helpful. Actually, I didn't add any fact model or Jar
files to Drools. I didn't reach to this level yet :P What I did on Guvnor is
simply design the process with variables and forms and build it. But
suddenly I found the processes in JBPM console and I started
This may not necessarily apply to you but it's worth mentioning - both
Designer, jBPM Console, and Guvnor assume by default they run on
localhost:8080. If you have configured one or all to run on a different
host/port you will have to make configuration changes.
You can find how to do that for
Is there a way to log what rules have interacted with a fact -- and keep the
logging with the fact? What are the best practices for that?
For example, facts are unmarshalled from an XML stream:

Then my rules interact with it:

Thanks! Issues with jBPM Designer should be reported in the jBPM project

Create an AgendaEventListener and let it listen to

reference to an Activation object, from which you getObjects all
