Drools Fusion in JEE environment
by IK81
Hi all,
i am planning to use the Drools engine in the stream mode within an JEE
application server. I have to process events of different users which can
define their own rules. So I plan to instantiate a stateful session for each
user and populate them with the user's rules. However, I am concerned how to
manage the firing of the rules - which might be delayed by some time because
of some rule statements (fire rule after having event A and no event B
within 3 minutes). Spawning a thread for each session and calling
fireUntilHalt is not an option in my opinion.
I've found a solution where somebody uses a scheduler within the container
to call fireAllRules at certain domain-specific intervals (e.g., every 10
seconds). I am wondering if there is a more clever approach. I am thinking
of providing a callback that can be used by Drools to notify when it has to
be "waked-up" again to fire the delayed rule.
Best regards,
Ingo

Iterating string objects inside Arraylist
by Ganesh R.
I am a novice in Drools, sorry if this question is trivial and has already been discussed. I couldn't find the direct method for implementing the below behavior.
I have a class like this.
public class Account {
public int balance;
public String id;
public List<String> types;
// getter setters
}
I am trying to check the following:
Accounts having balance greater than $100 and types containing both Savings and Checking.
// Creating sample Facts in Java main
Account account = new Account();
account.setBalance(100);
account.setId("A1");
List<String> temp = new ArrayList<String>();
temp.add("Savings");
temp.add("Checking");
account.setTypes(temp);
// Creating rules
rule "Sample"
when
bat : Account(balance == 100)
then
if (bat.getTypes().contains("Savings") && bat.getTypes().contains("Checking")){
System.out.println("I got this");
}
end
Is there more proficient ways to do this?? like checking the contents of the arraylist (types as per the above example) in rule i.e. in "when" instead of doing it in "then" ??
Much appreciate your answers.
Thank you!

VRP with multi-stream and heterogeneous fleet?
by Colin Sheppard
Hello all, I'm totally new to optaplanner / drools and would like to know
if the following is possible within the framework (I'd mostly likely use
version 6).
I have a VRP where we'd like to consider multiple waste streams
simultaneously (i.e. trash, recycling, food waste, and yard waste). We'd
also like to consider a fleet of split bin trucks (capable of collecting 2
streams at a time but with reduced capacity), single bin trucks, or a
mixture of split and single bin.
So the model would need to allow for a mixture of vehicle types, for nodes
to be visited more than once, and for simultaneous collection to occur in
the case of split bin trucks.
Does this sound like a feasible problem to implement? Would you anticipate
any major or intractable challenges?
Thanks for your advice, I hope I get the chance to start using optaplanner!

Internet Explorer Compatibility
by rjr201
Hi,
I'm working for a client who wishes to use Guvnor with Internet Explorer.
I've tried Guvnor 5.5.0.Final with IE8 and IE9. However, I get an error when
trying to access a rule in the guided editor.
I read in another post
(http://drools.46999.n3.nabble.com/guvnor-5-5-problems-on-Internet-Explore...)
that there are problems with 5.5.0 in IE, that may have been fixed in the
current 5.5.x branch.
I have built the latest code on the branch, but seem to have even more
problems (it doesn't even let me get to the initial Guvnor landing page).
Does anyone have any experience/insight in getting Guvnor working in IE? Or
at least know what version of Guvnor does work in IE? Or just any advice on
this issue at all I would be grateful..
Thanks in advance,
Rich.

Have you tested that the rules fire when you load them as DRL?
It would probably be worth showing us what EmployeeMap looks like and the rule which you expect to fire if there is an EmployeeMap in working memory.
The Drools version would also be useful.

Problems with the Mrs Manners Benchmark
by Sven Böcherer
Hello,
I am writing my dissertation on BRMS. I want to analyze the performance of
different systems. Drools is one of them.
I installed Drools 6 and wanted to start the Mrs Manners Benchmark for a
first analysis.
Unfortunately if I chose anything else but 5 guests, I get an infinite loop
where the program is never able to find the seating arrangement.
Attached you find a screenshot of what the console looks like.
I really hope you can help me with this problem.
Best regards,
Sven Böcherer

Am I doing something wrong? Or has anyone else come across this error?
Any help with this would be gratefully appreciated.
Thanks,

Getting infinite loops even with limitation of fires
by Bojan Janisch
Hello everyone,
Recently I'm using Drools in a multithreaded environment. But after a while I see that Drools is running for endless time even though I gave him with fireAllRules(1000) a limitation to fire only 1000 rules. The occurrence is rule-independent, I've checked multiple times and each time it's another rule which works well if I run it separately.
Could someone check the code of this stack trace? That's a thread dump of my last run.

Also here the rule and code snipped I'm using to prove that the infinite loop does not come from my code:
//kSession is a StatefulKnowledgeSession
try {
//Limiting the Activation will prevent infinite loops
kSession.fireAllRules(1000);
} catch (Exception e) {
System.out.println("error while processing :: " + e.toString());
System.out.println(rule);
} finally {
kSession.dispose();
}
-------------------------------------------------------------------
rule "308"
no-loop
when
$0:NormalizedNamedEntity(
ct_0:CoveredText,
cp_0:Concept,
label_0:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("ops"))
$1:NormalizedNamedEntity(
ct_1:CoveredText,
cp_1:Concept,
label_1:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("bodyside"))
then
int start = getStart($0,$1);
int ende = getStop($0,$1);
String attribute = label_0+" "+label_1;
insert(annotate(aJCas, "Operation", 309, attribute, start, ende, "", attribute));
end
I appreciate any help to solve this occurrence.
