[rules-users] Eclipse validator error
Hi, I am using drool IDE 3.0.6 on eclipse and saw bunch of errors on Eclipse Problem/ validator. The .drl file compiled and worked fine. But eclipse validators might not like the drl syntax and throw errors. Here are some errors: - The import (class) cannot be resolved - (declaration) cannot be resolved - Unable to resolve ObjectType I don't want to turn off all my Eclipse validator. Any body has any idea why I get those errors? Thanks, Tim ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Can't upload model in BRMS
I can't seem to upload a model into the BRMS. I also tried downloading and uploading the model in the insurance example and it failed. (I tried both the .war on tomcat 6.0.13 and the standalone version on tomcat 5.5.20). Can somebody help? Thanks, Mat ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] org.mvel.PropertyAccessException
Actions in RuleFlow are interpreted at runtime using MVEL. This error seems to
indicate that there is a problem in the syntax of your MVEL expression.
However, looking at your example, I do not see any problem,
System.out.println("Your text here"); as action property should work (I just
tested it with the 4.0.1 release). Could you open a JIRA and provide a
self-contained test that shows the problem?
That said, we still need to add syntax checking for actions during ruleflow
validation, to ensure that this error is encountered when checking the ruleflow
(at compile time) and not during execution.

RE: [rules-users] Adding constraints to facts in DSL
Hi Vincent,
Thanks for your answer but I would really like to use my synthax.
I need to write "or" between 2 constraints and not in a single
complex constraint.
If someone else could help me ...

Hello Stephane,
I think it's difficult to do that. Could you try this :
There is a Cheese with
- age is less than 42 or age is more than 60
- type is 'stilton'
with in your DSL
[condition][]There is a Cheese with=Cheese()
[condition][]- age is less than {low} or age is more than
{high}=age
< {low} || age > {high}
[condition][]- type is '{type}'=type == "{type}"
I don't see other solution...

Hello,
I'm using JBossDrools in my company and I have some problems with
DSL.
Actually, I would like to write something like this :
There is a Cheese with
( - age is less
than 42
or
- age is more than 60 )
- type is
'stilton'
Unfortunately, It's the drools parser which manage "-" char.
Also this previous synthax don't work in the LHS.
Anyone could help me to do an equivalent condition in my DSL ? If
possible with "-" sugar char.
Stephane.

[rules-users] Can't access binary rules package in application
Using BRMS, I created a rule binary package and downloaded it and am
trying to access it but I'm getting a NullPointerException. My code
looks like this -
public void main(Policy inputPolicy) throws Exception
{
RuleBase ruleBase = loadRuleBase();
StatefulSession session = ruleBase.newStatefulSession();
session.insert(inputPolicy);
session.fireAllRules();
}
private RuleBase loadRuleBase() throws IOException, Exception
{
BinaryRuleBaseLoader loader = new BinaryRuleBaseLoader();
loader.addPackage( this.getClass().getResourceAsStream(
"/underwriting.pkg" ) );
RuleBase ruleBase = loader.getRuleBase();
return ruleBase;
}
I'm getting the following error. Can someone tell me what I'm doing
wrong? Do I have something coded incorrectly?

Re: [rules-users] probliem in using "in" and "not in" operator in drool file.
Inside eval() you must use code in the chosen semantic dialect (either
Java or MVEL). None of them have "not in" operator that is a DRL syntax
sugar.
So, you need to either properly write Java or MVEL code inside the eval,
or use a regular DRL constraint.
In this specific case, if you are asserting the Map into the working
memory, you can do something like:
rule XXX
when
Map( this['name'] not in ("amit","siddhartha") )
then
// do something
end

[rules-users] Using DSL and accumulate in Drools BRMS leads to unexpected results
Hi,
I'm using the following DSL:
[when]There are at least {N} objects in the domain=Number(intValue>={N})
from accumulate ( i : Object(), count( i ) )
[when]- category is {Category}=category== "{Category}"
Using the above DSL from Drools BRMS leads to the following result (rule
source code):
Number(intValue>=10) from accumulate ( i : Object(), count( i,
category=="CATEGORY") )
Of course this is not the expected behavior. This should lead to something
like:
Number(intValue>=10) from accumulate ( i : Object(category=="CATEGORY"),
count( i) )
I have no such a problem when using the same approach with a collect
statement, i.e. the following source code is generated:
ArrayList() from collect ( Object(category=="CATEGORY") )
Is it a bug?
Regards,
CG

where validatorMap is a map of id and value inserted in global memory.
it is giving following error:

of drool.
Thanks.
