Re: [rules-users] Inserting Different Objects Of Same Class !
Yet another way would be to insert each List into a different entry point so that you might write List( ... ) from entry-point ListA AFAIK, you don't have a way of matching any List, though. -W On 27/11/2012, Esteban Aliverti esteban.alive...@gmail.com wrote: Well, there could be another way using one global for each of your lists (the lists should be inserted as fact just like you are doing) and then doing something like List( this == globalListA), but I never tried something like that. I think Wolfgang's recommendation (which is the same you have proposed) is the most elegant solution.

Entry points are partitions of Working Memory. See the Fusion manual and Drools' javadoc. List? listA = ... WorkingMemoryEntryPoint epListA = kSession.getWorkingMemoryEntryPoint( listA ); epListA.insert( listA ); rule matchListA when List(...) from entry-point listA then That's about all there is to it. -W On 27/11/2012, abhinay_agarwal abhinay_agar...@infosys.com wrote: entry point ?? can yu throw me some light on entry points ? -- View this message in context: http://drools.46999.n3.nabble.com/Inserting-Different-Objects-Of-Same-Class-tp4020971p4020980.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Drools Planner: Planning variable gets assigned value out of valueRange
Hey,
I have a planning entity, which has one planning variable called startDate.
This variable has a defined discrete value range which is a list of numbers
of the type long. Every number represents a timestamp, which is in between
the number firstPossibleStartDate and lastPossibleStartDate.
During the planning process, the number 0 is sometimes assigned to the
planning variable which is definitely not part of the valueRange. I’ve
printed the list to the console, but all values in the list are fine.
Because every planning entity has its own valueRange, the range is defined
in the entity itself.
At the moment I’ve implemented my own mover, but the problem occurs also
with pre-configured mover.
During my research I’ve stumbled upon the following note in the Planner
Documentation:
ValueRange from planning entity is currently not yet supported by the new
MoveSelectors.
Does this has something to do with my problem?
Enclosed you will find the code of the planning entity.
@PlanningEntity
public class DroolTask {
private ListLong startDateList;
private int id;
private String name;
private long duration;
private long firstPossibleStartDate;
private long lastPossibleStartDate;
private String nextTask = ;
private String previousTask = ;
// Planning variables: changes during planning, between score
calculations.
private long startDate;
@PlanningVariable
@ValueRange(type = ValueRangeType.FROM_PLANNING_ENTITY_PROPERTY,
planningEntityProperty = startDateList)
public long getStartDate(){
return startDate;
}
public void setStartDate(long startDate){
this.startDate = startDate;
}
public ListLong getStartDateList(){
return this.startDateList;
}
public void setStartDateList(){
startDateList = getPossibleStartDate();
}
public ListLong getPossibleStartDate(){
startDateList = new ArrayListLong();
for(long i = firstPossibleStartDate; i=lastPossibleStartDate;
i = i +
60){
startDateList.add(i);
}
return startDateList;
}
public Long getFirstPossibleStartDate(){
return firstPossibleStartDate;
}
public void setFirstPossibleStartDate(long firstPossibleStartDate){
this.firstPossibleStartDate = firstPossibleStartDate;
}
public Long getLastPossibleStartDate(){
return lastPossibleStartDate;
}
public void setLastPossibleStartDate(long lastPossibleEndDate){
this.lastPossibleStartDate = lastPossibleEndDate;
}
[...]
public DroolTask clone(){
DroolTask clone = new DroolTask();
clone.name = name;
clone.duration = duration;
clone.firstPossibleStartDate = firstPossibleStartDate;
clone.lastPossibleStartDate = lastPossibleStartDate;
clone.startDate = startDate;
clone.nextTask = nextTask;
clone.previousTask = previousTask;
clone.startDateList = startDateList;
return clone;
}
[...]
}
It would be great, if someone could give me a hint.
Many thanks,
Moe

[rules-users] Question about drools-spring in a multi-treaded container (like tomcat).
Hello all,
I've been reading up about drool-spring integration and have put together a
simple project that wires together a KnowledgeBase and KnowledgeSession as
follows :
drools:resource id=GroupUnit type=DRL
source=file:/Users/drools/drools-spring-test/src/Rules/drls/GroupUnit.drl /
drools:resource id=GradeUnit type=DRL
source=file:/Users/drools/drools-spring-test/src/Rules/drls/GradeUnit.drl /
drools:resource id=EvaluateUnit type=DRL
source=file:/Users/drools/drools-spring-test/src/Rules/drls/EvaluateUnit.drl
/
drools:grid-node id=node1 /
drools:kbase id=kbase1 node=node1
drools:resources
drools:resource ref=GroupUnit /
drools:resource ref=GradeUnit /
drools:resource ref=EvaluateUnit /
/drools:resources
/drools:kbase
drools:ksession id=ksession type=stateful kbase=kbase1
node=node1 /
Then in my Controller call, I 'AutoWire' in the StatefulKnowledgeSession as
follows :
@Controller
@RequestMapping( value = foo )
final class FooController{
@Autowired
StatefulKnowledgeSession ksession;
@RequestMapping( method = RequestMethod.GET )
@ResponseBody
public String evaluateUnit() {
Unit unit = new Unit(030, 502, C, 9484, 45, new String[] {},
null);
if (ksession != null) {
ksession.fireAllRules();
ksession.insert(unit);
ksession.fireAllRules();
return UnitCategory + unit.getUnitCategory() + /UnitCategory;
}
else
return message stateful session is null/message;
}
The main question that I have is that – is this solution thread-safe ? From
what I understand of spring is that beans configured without any additional
qualifiers are inherently singletons. And when deployed in a multi-theaded
container like tomcat, Spring assumes that the beans being severed up a
thread-safe. So from I have read is that KnowledeSessions are inherently not
thread safe. So putting the 2 together, I leaning towards the assessment that
this above solution is NOT thread safe and that if I do want it to be thread
safe I should set the StatefulKnowledgeSession to 'prototype' and not leave it
as a singleton.
Please let me know if I'm missing anything in my assessment here !
Thanks in advance,
Gurvinder

[rules-users] Drools response time
Dear all, I need to develop an Expert System for a new project and I want to use Drools, butI have some restrictions. The most important restriction: response time of the application must be less than one second. Also, the application access to one data base to retrieve some information and send it to the expert systetm. With this information, can anyone tell me, approximately, the response time of Drools? It is very important to can use Drools in this project. And we like very much to use it. (We use in other projects without these restrictions). Thank in advance.

Hi Jesus, Well do you want us to include the response time for your Database? The Drools Rule engine will keep all your facts inside the main memory (RAM) so it will be fast, but if you need to retrieve data from your database, you will need to take that into account. Depending on how you are doing that and how much data do you want to bring will be the response times.

Re: [rules-users] Question about drools-spring in a multi-treaded container (like tomcat).
Hi Gurvinder, knowledge sessions are not thread-safe so I believe your assumptions are correct. To be on the safe side you should change the ksession bean to have scope prototype.

Re: [rules-users] Inserting Different Objects Of Same Class !
Are the values in the list ever tested? (With rules conditionally firing if the contents of a list changes.) In the rules you've provided so far they are not. If this is the case then there's no need to match them in the conditions and the use of globals is just fine. The only reason to match a list in the rule conditions is if changing the list could result in that rule firing.

I was initially using two lists making them global, and it was working for me, but then i read Globals are not designed to share data between rules and they should never be used for that purpose. Rules always reason and react to the working memory state, so if you want to pass data from rule to rule, assert the data as facts into the working memory. So, thought might be somewhere, an issue can arise and changed the global facts.
