Rules migration from ILog
by Tomas Andersen
Hi.
We are thinking about using Drools instead of Ilog for a current project.
I have some ilr files containing rules/decision points. Is it possible to convert/migrate these to drl files to be used in Drools?
If not does anyone know if there is a way to import ilog rules into drools. We have excel scenario files and/or ilr files as a base.
Regards,
Tomas

FW: FW: Capitalized element names
by Tom.E.Murphy＠wellsfargo.com
Thanks, Wolfgang.
Is it possible the error is in the internal treatment of caps in the code that converts
MICompanyMarketClassification in ("2", "3")
to
MICompanyMarketClassification == "2" || MICompanyMarketClassification == "3"
Why I think this:
The only place the capitalization seems harmful is when it occurs with an in (...) clause.
If I use forced lower- casing of the first letter of a capitalized property in other types of expressions, 5.2 fails.
If I use forced lower-casing of the first letter of a capitalized property in an in(...) expression, 5.2 succeeds.
If I use natural casing of a capitalized property in other types of expressions, 5.2 succeeds.
If I use natural casing of a capitalized property in property in an in(...) expression, 5.2 fails.

Edson,
please also not JBRULES-3147: Regression: all uppercase field reference results in compile error. Some forms used to work in 5.1.1 that don't in 5.2.
I've added the gist of this thread to JIRA-3147.

>>
>> 1. I have other elements in other objects referenced within the same rule group that start with capital letters and they have no problem. Example:
>>
>> , FHAMaxBaseMortgageWithToleranceAmt < ($totalLoanAmt+$aggregateSubordinateFinancingAmt)
>>
>> Compiles just fine in the same session.
>>
>> 2. If I lower the first M to m to make it mICompanyMarketClassification, it compiles in 5.2 but does NOT compile in 5.0.1
>>
>> 3. If I leave it as the capitalized MICompanyMarketClassification, it compiles in 5.0.1 but not 5.2
>>
>> Thoughts?

>> I've seen this before and AFAIK, the javaBeans spec always transforms the first letter to lowercase when converting a get method into a property name. We can try to address this in future releases, maybe falling back to uppercase if the lower case property name lookup fails, but I don't think there is a solution to keep it as is. In 5.2. you can use the full method name instead, but not sure if that isn't event worse:

Declare new fact type - where do i put it?
by Eugenia Carcel
I want to declare a new fact type, but I don't know where to put it.
In a java file? It's not java syntax... In a drl file?
I've already went through the docs but this piece of info is missing...
Thanks again,

Unable to build constraint as '_default' is invalid
by Eugenia Carcel
Hi,
I get the following error when I try to build and deploy:
Unable to build constraint as '_default' is invalid : [Rule
name='myRuleName']
It yields this error because of this pattern in my drl file:
MyType(_default == DefaultType.YES)
In my java class MyType I have something like this:
public class MyType {
....
@XmlAttribute(name = "default")
protected DefaultType _default;
....
}
where DefaultType is an enum.
Here is the hole enum class:
@XmlType(name = "defaultType")
@XmlEnum
public enum DefaultType {
@XmlEnumValue("yes")
YES("yes");
private final String value;
DefaultType(String v) {
value = v;
}
public String value() {
return value;
}
public static DefaultType fromValue(String v) {
for (DefaultType c: DefaultType.values()) {
if (c.value.equals(v)) {
return c;
}
}
throw new IllegalArgumentException(v);
}
}
Can you help me? I don't see where the problem is...
Any suggestions are much appreciated.

Rules influencing each other ?
by Andre
during my tests i see, that when data is evaluated from other rules than the
third one, the third will not fire, even if the right combination of events
occur
and when the same events occur without any other events, then the third one
works , any idea ??
rule "Request counting Subject By Id"
when
$set: Set()
from accumulate($neu : RequestCtx() over
window:time(1m),countMatchingSubjectIdsInRequest($neu) )
java.util.Map.Entry( $id: key, $count: value > 1 ) from $set
eval(DroolsUtils.isUpToDate($count))
then
channels["AuthZBlocking"].send(new ItemCacheEntry(new Item((String)$id),
new Date(System.currentTimeMillis()+ 30000),new StringMatcher()));
end
// Implementing Use Case 2
rule "Request counting Resources By Id"
when
$set: Set()
from accumulate($neu : RequestCtx() over
window:time(1m),countMatchingResourcesInRequest($neu) )
java.util.Map.Entry( $id: key, $count: value > 1 ) from $set
eval(DroolsUtils.isUpToDate($count))
then
channels["AuthZBlocking"].send(new ItemCacheEntry(new Item((String)$id),
new Date(System.currentTimeMillis()+ 30000),new StringMatcher()));
end
// Implementing Use Case 3
rule "Request counting analysed Resources By Id"
when
$list: ArrayList()
from accumulate($neu : RequestCtx() over
window:time(1m),countMatchingAnalysedResourcesInRequest($neu) )
ResourceMatch( $id: uri, count > 1 ) from $list
then
channels["AuthZBlocking"].send(new ItemCacheEntry(new URIItem($id), new
Date(System.currentTimeMillis()+ 30000), new URIMatcher()));
end

evaluating different aspects of the same event
by Andre
i want to accumulate on different properties of my event.
i have 3 rules which all work in the same manner , accumulate on that event
and then work with that result
my rules are all like this
rule "Request counting Subject By Id"
when
$set: Set()
from accumulate($neu : RequestCtx() over
window:time(1m),countMatchingSubjectIdsInRequest($neu) )
java.util.Map.Entry( $id: key, $count: value > 1 ) from $set
then
channels["AuthZBlocking"].send(new ItemCacheEntry(new Item((String)$id),
new Date(System.currentTimeMillis()+ 20000)));
end
these rules should work concurrently, depending on the propterties.
to test this i wrote...
let us assume:
Rule1 looks for A.A and if |A.A>1| fire
Rule2 looks for A.B and if |A.B>1| fire
Rule3 looks for A.C and if |A.C>1| fire
i inserted
A.A
A.A
A.B
A.B
A.C
A.C
and instead of firing 1,2,3
the engine fires : 1,1,2,1,1,2,1,2
Do i have to influence the agenda , when working on the same eventtype ??

Processing a collection within a fact object
by kirkm
I have an application that is inserting a fact object into a session. The
object has a collection in it that is being iterated and each of the
individual children objects is being inserted into the session with a
reference back to their "parent" object. The child facts cause other rules
to fire and the children objects are updated in some situations. Is there
any way to determine if all the rules have fired due to the children
insertions? The desired result is to have a parent object with possible
updates to the children for further processing.
Can and should an accumulator be used instead of the inserting the child
objects?
