change-set schema location
by grimace
should it be this:
xs:schemaLocation='http://drools.org/drools-5.0/change-set
drools-change-set-5.0.xsd'
or this:
xs:schemaLocation='http://drools.org/drools-5.0/change-set.xsd'
I don't see an .xsd file at either of those locations.
and I am getting warnings trying to read a change-set file:
(null: 4, 99): schema_reference.4: Failed to read schema document
'drools-change-set-5.0.xsd', because 1) could not find the document; 2) the
document could not be read; 3) the root element of the document is not
<xsd:schema>.
(null: 4, 99): cvc-elt.1: Cannot find the declaration of element

or this:

'http://drools.org/drools-5.0/change-set.xsd' must have even number of
URI's.
(null: 4, 77): cvc-elt.1: Cannot find the declaration of element

decision tables and default rules for case when part of LHS failes for other rules
by Syargey
Hi all,
I have been asked to add default rules to a decision table.
We have a decision table with several conditions. Data from first two
columns are passed to action with binded variables. The action collects data
from all passed rules.
-------------------------------------
condition 1 | condition 2 | ... | action
-------------------------------------
AAA | AD | ... | X
-------------------------------------
BBB | AD | ... | X
-------------------------------------
BBB | AE | ... | X
-------------------------------------
BBB | CC | ... | X
-------------------------------------
CCC | AD | ... | X
-------------------------------------
DDD | AD | ... | X
-------------------------------------
BBB | AE | ... | X
-------------------------------------
... | ... | ... | X
-------------------------------------
Recently business asked me if it is possible to have default rules (rows) in
the table if there is not any rule passing condition 1.
-------------------------------------
DEFAULT | AD | ... | X
-------------------------------------
DEFAULT | AE | ... | X
-------------------------------------
Is it possible to have rules in decision table those can be fired only if a
specific part of LHS never occurs in others rules?
Thanks in advance,
Syargey

RuleSet (RuleFlowGroup)
by rchemisa
Hello,
I'm trying tp understand how does the Rule Set works and I'm experiencing
some problems. I need it to stop
when the process finds a 'rule set' and it doesn't match with the
conditions, however, the process continues even the facts do not fulfill the
conditions.
Can someone explain me how does the 'rule set' works or can u give an
example?
thank you very much

Serializing knowledgepackages - execution behaviour
by FrankVhh
Hi all,
After playing with serializing knowledgepackages a bit, I stumbled upon some
behaviour which I cannot explain at the moment. I can only hope someone can
deliver a hint of insight into this.
The situation:
Creating and executing a rule engine with the very same rules. In the first
attempt, rules are serialized first. Note that only the rules are
serialized, not the engine.
In the second attempt, the "normal" (= "as in the hello world sample")
procedure is used to feed the rules to the engine.
I noticed some performance differences at execution time, which amaze me a
bit, as I can't see a reason why execution would differ...
When loading the serialized rules, rule execution is slightly slower and,
more important, there are some glitches in the performance (execution times
over 10 times slower than average execution). Unserialized rules run much
smoother and much more consistent.
Does anyone have any explanation for this? I am very interested to find out.
Thanks a lot.
Regards,
Frank

Re: [rules-users] Rule error
by FrankVhh
Hi,
It depends upon which version of drools you are using, but if it is a
version pre 5.2.0, than your last line should be:
eval($c.getDoMin()>=$m.getDoMin())
If you are using 5.2.0, the parser allow a bit more freedom, allthough I am
not sure about this very case. You surely will have to omit the ; at the end
of your condition.
Regards,
Frank
