[rules-users] KieScanner with Maven 3
Hello, Does the KieScanner support Maven 3? I noted that LATEST, RELEASE and SNAPSHOT metaversions for Maven are no longer supported by Maven 3 so do I have to understand that we cannot use the KieScanner with Maven 3? By the way I noted that if I set my KieContainer with a LATEST version, the KieScanner systematically redeploy my JAR as the KieScanner compare the real version with "LATEST". I've seen that there were some changes in the KieScanner in the 6.1.0, did you fix it? I can't test right now because I face a rule compilation problem with the new 6.1.0 version and I still have to figure this out.

Re: [rules-users] Pooling stateful sessions to have threaded executions of a ruleset
I'm disposing after use because if i'm not the working memory is not empty
between 2 calls right ? And I am saying that I'm using them as a pool
because I have 5 sessions that could be used at the same time, which is
impossible if I declare only one.
If you have recommandation for my use case, please tell me as I found
nothing in the doc about this.

Re: [rules-users] Pooling stateful sessions to have threaded executions of a ruleset
I'm sorry but I don't understand what you are talking about. In this
article, there is nothing about multithreaded rules evaluation. It just
says that the Phreak algorithm is designed for thread safety and
*future*multicore processors exploitation. It doesn't mean that it is
already
multithreaded. Moreover I tested my appliciation with and without
multithreaded sessions (I am using Drools 6.0.1.Final) and I noted a faster
execution in the multithreaded one.

[rules-users] Pooling stateful sessions to have threaded executions of a ruleset
Hello,
I want to ask you if it is a good practive to pool stateful sessions for a
specific ruleset to improve the execution performance.
Actually in my application I execute my rules by calling SOAP webservice.
For performance purpose, I test multithreaded calls to my webservice and I
noted that when I pool sessions in the server side, it improves the
performance a lot.
To pool sessions, I just declare multiple ksession tag in my kmodule.xml :
In my spring webservice endpoint I just put that code to handle the pool :
@Endpoint
public class ExampleEndpoint implements InitializingBean {
@Autowired
private ExampleRuleService ruleService;
private Map isRunningMap = new HashMap();
private static final int NB_POOL_SESSIONS = 5;
@PayloadRoot(localPart = "com.example.ExampleRequest")
@ResponsePayload
public ExampleResponse handleRequest(
@RequestPayload ExampleRequest request) throws
InterruptedException {
KieServices ks = KieServices.Factory.get();
KieContainer kc = ks.getKieClasspathContainer();
while (true) {
for (int i = 0; i < NB_POOL_SESSIONS; i++) {
boolean run = false;
synchronized (isRunningMap) {
if (!isRunningMap.get(i)) {
isRunningMap.put(i, true);
run = true;
}
}
if (run) {
KieSession ksession = kc.newKieSession("KSession" + (i
+ 1));
ExampleResponse response = ruleService.run(ksession,
request);
ksession.dispose();
isRunningMap.put(i, false);
return response;
}
}
Thread.sleep(100);
}
}
public void afterPropertiesSet() throws Exception {
for (int i = 1; i <= NB_POOL_SESSIONS; i++) {
isRunningMap.put((i - 1), false);
}
}
}
It works well because in my benchmark I improve 5 times the performance (as
I have 5 different threads) but I wondered if it is a good practice and if
it does not hide any issues that I could have in the future.
Thanks for your help.

Re: [rules-users] Not able to detect how to correct ERR 102
Try with this :
rule "hello rule"
when
There is a Customer with first name "David"
then
Greet Customer
end
and this DSL :
[condition][]There is a Customer with first name {name}=$customer :
Customer(firstName == {name})
[consequence][]Greet Customer=System.out.println("Hello " +
$customer.getFirstName());
-
Of course your DSLR file is dependent of the DSL. Without the DSL, Drools
cannot guess what you want to do.
