You are right, I need to re-think what I am doing. Perhaps there is no need
for me to do the update() calls. I will post back. Thanks.

I have /update()/ on consequence/action part of rules, which I can't void. I
guess there is no way and rule engine is doing the right thing then.

Makes sense, pretty good explanation.
Is there a way to turn this behaviour off? I don't want the rule engine to
re-calculate the rules when I update a fact inside the rule engine. Is that
possible? The reason I ask is that in my application it makes sense based on
the way I have structured the ru

I have the same question. I see this happening, and I don't know why.

This issue I have been facing has been resolved. I have been informed of a
better way to see the errors (another thread). Some of the domain objects
were returning def (i.e. Object) instead of Boolean. This was working in 5.2
but failing in 5.3. I changed the code. It is working now.

Just to be clear, some of the methods from my domain objects I was using "def
isListed()" etc, because it is groovy. I had to change it to "boolean
isListed()". So I had to update some of the rules in 5.3. This was fine in
5.2.

Hi laune,
Thank you so much! My problem is solved. I copied a portion of your code
that prints the error messages into my RulesService.groovy. It prints
accurate error messages now!
Thanks,

This is the dependency that I have in my grails/drools application after
upgrading to 5.3. This eliminates all the ClassNotFoundErrors. I think I
resolved the dependency issue.

Hi,
I am using Drools 5.2 (direclty, not via grails plugins) in a grails
2.0.0.M2 web application. I use IntelliJ IDEA for development which does not
support Drools inherently. (I know eclipse has better support) I am
struggling with the compilations, syntax erros of .DRL file I have in my
app. Ar
Yes locally in machine just to make sure i have only drools upgrade
happening. My issues are because of this upgrade guaranteed.
The error message drools is giving me is misleading:

No stacktrace, nothing :o

Hi manstis,
I will look into incorporating knowledge-api jar and try. Thanks.
Anywhere these dependencies are documented clearly?
The issue is clearly drools related, i have isolated this already in another
git branch meant only for drools upgrade.

Hi,
I was using drools 5.2.0 in my grails 2.0.0.M2 application. I use Drools

HI,
There was one bad rule, when I removed that memory leak is gone and the
performance improved drastically!!! (from 60 sec for 1000 records to 10
seconds, satisfies our requirements) I am not sure what is wrong with the
rule, I will check that tomorrow, I am a happy man now.

Hi Edson,
Yes I am calling displose().
No I have not tried 5.3 it, I will give it a shot. What was the issue with
jbpm being in the class path, is it related to memory leak over time?
AS for MBeans, thanks, I will try that also.
What I am doing now is removed all rules, putting one rule at a ti
Hi,
Are there any instructions on how to enable JMX Beans and monitor Drools
using JConsole or JVisualVM anywhere?

Hi,
I am not much of an expert on Drools. I got a DRL file (very small rule set
of less than 10 rules, that checks few conditions, also includes DB calls).
I use Drools 5.2 inside a grails application. I am using stateful session. I
call this rules 100,000 times for each for each of the 100,000 re
Is there a way to log / monitor the time taken for rule in a Drools rule set?
Is there a way to make sure that one rule is not executed more than once(It
seems to be happening in my case)
What are the general guidelines on improving Drools performance?
Currently I am using a one single DRL file
