Thanks for your response Marc.
I've also test this functionnality with the 5.5 version and I've got the
same error.
Do you know if this will be resolved in the next release ?
Thanks,
Didier

Hi,
I have two rule files(rule1.drl and rule2.drl) first file contains 5
rules and the second one contains 9 rules.
Each rule contain 2 or 3 patterns .Also objects used by every rules are
same. Objects contain two lists
and size of these list can vary according to the situation.

Are all of your facts of the same class? How many fact objects do you
have? How many objects are in the two lists of these facts? Please be
more precise.

A java.lang.NullPointerException was caused for unknown reason by

It will have to be fixed in most places.
And here is another one:
KieBuilderImpl.generatePomProperties uses \n for line delimiters.
That's not a problem with XML, where it only affects the readability.

Could you please open a JIRA ticket, and/or submit the DRL fragment that
causes the exception?
Sometimes NPEs are symptoms of problems that happen elsewhere and do not
manifest until much later.

Hi,
All of my facts are of the same class. One of these list contain only one
object and in the other list contain sometimes 0 objects and sometimes it
can be 5 or 6.

Then it is very likely that rules with 3 patterns referring to the
same, single class cause the excessive memory consumption.
You'll have to show us such a rule and explain why you think you need
to write the patterns the way you did - then, we should be able to
propose a solution.

You have (at least) two different fact classes: Alert and Information (not
just one, as you write).
The rule you have shown has only two patterns - I was asking for one with
three patterns (as I was thinking they had all to be of the same class).

Hi Daniel,
thanks for having reported this ... as you can imagine we don't have many

Anyway I just fixed this issue and the fix will be available starting from

Thanks again and regards,

If we create a KieBase from a Jar, all rules has to be placed in
src/main/resources (why ?).
That means, it is not possible to build a jar with maven, beacuse maven
puts all resouces in the root folder of fhe jar.
Ok, we build a zip, using the maven assembly plugin.

it's certainly easy for someone to attempt :)
I'm not sure if the JPA persistence and transactions will be a problem here or
not. If i'ts not, it's easy, if it is, it's hard.

Hi,
We are in the process of building a deployment script where-in we have to
migrate individual assets from drools guvnor to a centralized repository.
Eventually we will be using the centralized repository to generate packages
for runtime deployment.
Is it possible to download a POJO model
Use http://hostname:port/jboss-brms/rest/packages/{packageName}/source to
get the DRL file source.
I guess GDST is like an excel sheet on top of which rules are written. So if
you are migrating it from one repo to another, you have to migrate this
asset as gdst but if you just need DRL, get it
