Thanks Kris. We were able to log events and now its in BIRT arena to
generate some reports.
Thanks for your help.

@Robert,
See if this helps:
TaskService taskService = new TaskService(emf,
SystemEventListenerFactory.getSystemEventListener());
MockUserInfo userInfo = new MockUserInfo(); // this of course is a mock
only if it is a TEST :)
taskService.setUserinfo(userInfo);

@Thomas,
That is exactly what I mean. Have a default "language" exception
handling mechanism, by which all unmapped exceptions would be converted to
"ProcessRuntimeException" and will go to the "Fault" with type, let's say,
UnknownProcessExceptionFault. And have an option to turn this behavio
OK, thanks for quick response, I'll try that tomorrow morning.

The environmentMode property is new on trunk.
It is not part of drools-planner (drools-solver at the time) 5.0.1 or
5.1.0.M1.
It will be part of 5.2.0.M2.
Note that a drools-core/compiler M2 snapshot is unstable at the moment
(that's why they call it trunk :).
What you can do - in theory - is co
If you add a map when starting a process, those values will be set as
process variables. For example:
[ a : "SomeString"; b : 3 ].
Simplest way to access these variables in a constraint is using a code
constraint, something like:
return "SomeOtherString".equals(a);
or
return b > 2;
So you can
This seems to indicate that the version of the drools-api (containing
ChainedProperties) that he task service is using is not the one it was
compiled with. Make sure you are using matching drools-api and
drools-process-task jars.

I'm not convinced that converting a java exception to a process fault with the
same name is a solid behaviour.
In java it is perfectly permissible and valid for a piece of code to change the

Are you working with the trunk? or with which Drools Version?

Guvnor was changed recently to add authentication when downloading packages.
The console was not yet updated for this in 5.1.0.M1, so you'll need to update
to the latest trunk. Luckily, there's now also an installation script that
should simplify things as well.
Take a look at

Java version is 1.6.0_18

Hi
Do we have a performance comparison chart between Drools 3.0 and Drools 5.0?
I see we have one between 4.0 amd 5.0 and one between 2.5 and 3.0.
But missing the 3.0 and 5.0 comparison.
We recently moved to 5.0 from 3.0 and see significant drop in performance.
Need to check if the drop is relate
Ade,
All these errors you are seeing are totally strange, as this is one of
the simplest things the rules engine does. Are you able to isolate that into
a test case that I can run myself to take a look?

I guess we'll have to see class IndividualDecision, at least everything in
connection with that loanToValue: field declaration and getter and setter.

Which version of the JVM are you using?

The main problems I see when translating a java exception to a process
exception automatically:
- the exceptions are too low level, no business user understands
NumberFormatException or ClassCastException, and the error could come from

Hi,
I'm stuck on this "simple" problem for two days now and I couldn't find the

There is a little bit of documentation about how to create a history log:
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-flow/html/ch05.html#d0e1593
... and how to do reporting:
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifac
Another alternative would be to use an activation group, that way only one rule
of that group will be able to fire.

Nol,
Process variables are local to your process instance. Rules work based on
data inserted in the session. So you should probably make sure your process
inserts the data in the session at the appropriate time (e.g. using an
action that does kcontext.getKnowledgeRuntime().insert(..).

Well, then drop the
dialect "mvel"
and write the pattern as
$d : IndividualDecision( loanToVal < 85.0 )
There's no visible need to use mvel.
Or eval: the simplest form for constraints is always best.

I cannot find an example of this in the documentation and a search on the
mailing list was fruitless.
Right now my test process works fine - the constraints in Split Nodes are
set "always true" with different priorities.
I need to access the variables inside the Map parameter sent into the

Many thanks for the response!
Yes it fires when I use 85.0 instead, but it obviously shouldn't as the
condition is false. My code now looks like this:
