[rules-users] Drools Guvnor 5.4.0.Final running on JBoss AS 6.1
Hi all, I am running Drools Guvnor 5.4.0.Final on JBoss AS 6.1. I removed some libraries that were conflicting, and I also removed from the web.xml, the BeanManager resource env. After those changes, the app starts up, but it fails when bootstrapping Weld, when wrapping injection target to IdentityImpl class, failing on unsatisfied dependencies. The reported error varies, as sometimes the unsatisfied dependencies are [HttpSession] , [Credentials] or [PermissionMapper]. I am stuck on this error, any input is much appreciated. The detailed error message: Deployment vfs:///myPath/jboss-6.1.0.Final/server/default/deploy/myAPP.war_WeldBootstrapBean is in error due to the following reason(s): org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [HttpSession] with qualifiers [@Default] at injection point [[field] @Inject org.jboss.seam.security.IdentityImpl.session], **ERROR** Deployment java:global/cdi/myAPP/myAPP/BeanManager is in error due to the following reason(s): ** NOT FOUND Depends on 'java:global/cdi/myAPP/myAPP/BeanManager' ** or Deployment vfs:///myPath/jboss-6.1.0.Final/server/default/deploy/myAPP.war_WeldBootstrapBean is in error due to the following reason(s): org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [PermissionMapper] with qualifiers [@Default] at injection point [[field] @Inject private org.jboss.seam.security.IdentityImpl.permissionMapper], **ERROR** Deployment java:global/cdi/myAPP/myAPP/BeanManager is in error due to the following reason(s): ** NOT FOUND Depends on 'java:global/cdi/myAPP/myAPP/BeanManager' ** Excluded libraries from war: xml-apis-1.3.04.ja xmlParserAPIs-2.6.2.jar jsf-api-1.2.jar jta-1.1.jar jaxen-1.1.1.jar jaxb-xjc-2.2.5.jar weld-servlet-core-1.1.6.Final.jar weld-api-1.1.Final.jar weld-core-1.1.6.Final.jar weld-spi-1.1.Final.jar xercesImpl-2.9.1.jar dom4j-1.6.1.jar cdi-api-1.0-SP4.jar javassist-3.14.0-GA.jar javax.inject-1.jar jboss-interceptors-api_1.1_spec-1.0.0.Beta1.jar jsr250-api-1.0.jar persistence-api-1.0.jar shrinkwrap-api-1.0.0-cr-1.jar shrinkwrap-impl-base-1.0.0-cr-1.jar shrinkwrap-spi-1.0.0-cr-1.jar Thanks,Patricia___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Drool rules vs java code, effiency
Hello, This is what i think (has to be confirmed from specialist) Every thing you do in Drools you can do it as well in Java. But if you have a modification on your java code, you have to modify, then compile and deploy. contrary to the Drl rules which are interpreted, so after modification you don't need to do any thing just save your modification. So in the case of drools you have some flexibility which means that the rules can be managed directly by the decider and not the developer. regards, Cheikh Le 29/10/2012 23:57, kina06 a écrit : Please don't ignore this question as routine, did google and read posting, didn't get satisfying answer, hope you guys can help.

Re: [rules-users] Drool rules vs java code, effiency
See below. On 30/10/2012, Esteban Aliverti esteban.alive...@gmail.com wrote: For simple validation rules the main benefit of using drools is the decoupling of your business logic from your application. Another benefit is the power of DRL language. For example, implementing the 'exists', 'collect', 'accumulate', 'from' etc. behavior in plain java is not a trivial task. This enumeration omits the most important feature available in a rule's condition: the dynamic creations of all Cartesian products of facts matching the constraints. Example: $p: Person( age = 60 ) Car( owner == $p ) This finds all cars owned by persons over 60, which relieves you from the task of writing loops to determine all matching combinations, which can become quite cumbersome with increasing complexity. In Drools you already have all that power and you can create really complex rules with just a few lines of DRL. For more complex scenarios, you can use Drools for: - make inference (impossible to do in java without implementing some kind of inference engine). - use temporal patterns in your rules. - Use TMS - more... There is the option of creating a domain specific language on top of DRL, which is one way of making your business logic intellegible to non-programmers, so that they can at least understand what's going on. -W Best Regards, Esteban Aliverti - Blog @ http://ilesteban.wordpress.com On Tue, Oct 30, 2012 at 9:43 AM, cheikh dhib dhib.che...@gmail.com wrote: Hello, This is what i think (has to be confirmed from specialist) Every thing you do in Drools you can do it as well in Java.

Re: [rules-users] Guvnor 5.4.Final can't save BPMN process imported from 5.3 repo
I don't see any Designer specific error(s) in your provided logs. This seems like a possible issue with Guvnor and the Drools Eclipse plugin. Will deffer to experts in that field to provide more info. Just FYI, with jBPM easiest way to get started is to use the jBPM installer which bundles the AS, Guvnor, Designer, jBPM Console, and Eclipse (with proper plugins). With the new release around the corner you could either wait for that or use the latest jBPM release bits on sourceforge.

Does update(account) causes all rules to be rerun? I don't want that, at the
same time I don't want to use modify as it's not very easy to use, I have
several rules that I will hve to change
I like the option of coding like the following and then one function call
that will notify the rule engine that this object is modified so next rule
has latest changes.
account.setSomeField(');
account.setStatus('');
account.setExpiry(xyxCalss.getExpiryDate());
NOW call a function to notify that account is changed.
How can I do it?

Re: [rules-users] Field value is different when and then section, very strange. Is it mvel vs java issue
This is a list for support of the drools product, but there is some expectation that you will figure out some basic functionality by reading the docs and putting some thought into it. :) In general, though, the next rule is whatever rule matches the objects currently in working memory. If you don't want a given rule to fire you should make sure that the objects altered no longer match it after they are changed. In your original example the Account object matched in Rule1 has no conditions on it at all, meaning any Account in working memory will be matched, so it's no wonder that it's being matched repeatedly. Also, I'm puzzled by your calls to StringUtils.equals() in the rule conditions. Did you not try this? account : Account(accountStatus == NEW) Again, in the docs, this is the recommended way to test object properties.

Re: [rules-users] Calling Technical rule assets in Guvnor
Are you sure the AgendaFilter is not causing the Technical Rule to be

Hi,
How to call Technical rule assets stored in Guvnor from Java application?
Currently I have one drl rule which is stored in Technical rule assets

But I am not able to call it from my Java application.

KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
try {
kbuilder.add(ResourceFactory.newInputStreamResource(urlResource

ResourceType.PKG);
} catch (IOException e) {
e.printStackTrace();
}
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
// create session
StatefulKnowledgeSession session = kbase.newStatefulKnowledgeSession();
NyssCaseSO caseSO = droolsRequest.getNyssCaseSO();
NyssCaseStateSO caseState = caseSO.getNyssCaseStateSO();
NyssOfferSO offerSO = droolsRequest.getNyssOfferSO();
session.insert(caseSO);
session.insert(offerSO);
session.insert(caseState);
AgendaFilter filter = new AgendaFilter() {
public boolean accept(Activation activation) {
if (activation.getRule().getName().contains(testDrl)) {
return true;
}
return false;
}
};
session.fireAllRules(filter);
for (Object o : session.getObjects()) {
if (o instanceof ResultSO) {
ResultSO resultSO = (ResultSO) o;
reply.setResultSO(resultSO);
}
}
session.dispose();
With above I am able to call my rules stored in *Business rule assets*
section.
Thanks,

Re: [rules-users] Field value is different when and then section, very strange. Is it mvel vs java issue
Identify the requirements for changing your data. For instance, what
*exactly*
is the state of an Account fact x when it should be subject to
x.setAccountStatus( PENDING );
Any value of accountStatus? All values *except* PENDING? null? ...?
Make sure to constrain Account() in this and any other rule by adding the
correct boolean expression between the parens.
modify( x ){ set...(...), set...(...) } is the preferred way of notifying
the Drools
Engine that a fact has changed and all rules potentially referring to this
fact need to be reconsidered; the fact's history is irrelevant.
x.set...(...); x.set...(...); update( x ); is essentially the same.
Using salience is (usually) the wrong approach, as is no-loop, which
will avoid only on-the-spot reactivation - you can still loop over two or
more rules.

Re: [rules-users] Field value is different when and then section, very strange. Is it mvel vs java issue
You can stop the recursive firing by 1) having conditions in the rules that stop recursion, (similar to a stop condition in a for loop) and 2) using update or modify to tell the rules engine that the properties have changed.

Re: [rules-users] Field value is different when and then section, very strange. Is it mvel vs java issue
Code put in this posting is just a sample code I have put together to test this functionality. So modify/update will cause all rules to rerun, in that case I need to make sure that each rule is atomic and be idempotentn, i.e. to be able run the rules n times still no same consequence. What's drools.halt() used for, does it halt the rule process for that fact or for all facts in teh session? -- View this message in context: http://drools.46999.n3.nabble.com/Field-value-is-different-when-and-then-section-very-strange-Is-it-mvel-vs-java-issue-tp4020550p4020585.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

Re: [rules-users] Field value is different when and then section, very strange. Is it mvel vs java issue
When an object is insert in the working memory, it will be matched against
all rules: some of them will become active, because the logic expressed in
there applies to your fact, some others will not.
So, Wolfgang has pointed out an important detail: make sure that there is a
strong logic correlation
(implication) between the conditions in the LHS and the actions in the RHS,
so that you don't execute
unwanted actions.
Given the fact that evaluation and execution take place in two different
stages (see Esteban's email
for details), a change in the object's status MAY invalidate the conditions,
but the engine needs to know about that: by the time a rule is executed, it
won't go back and double-check the conditions unless told so.
So (citing Greg this time): if your logic is sound, and you apply modify
appropriately, you should not get
into a loop - or, if you do get into a loop, it's because it's necessarily
imposed by the application logic
(I'm assuming that there are other external ways to control the loop
termination), for example:
rule controlled loop
when
$x : X( $n : val 10 )
then
modify ($x) { setVal( $n + 1 ); }
end
as opposed to:
rule loop
when
$x : X( $n : val )
then
modify ($x) { setVal( $n + 1 ); }
end
rule breaker
salience 10
when
$x : X( val 10 )
then
retract( $x );
end
This said, there are cases when your same fact is shared between two
separate contexts:
rule One of rules dealing with age
when
$p : Person( $a : age )
$b : Birthday( person == $p )
then
modify ($p) { setAge( $a+1 ); }
end
rule One of rules dealing with salary
when
$p : Person( $s : salary 100 )
then
modify ($p) { setAge( $a+1 ); }
end
Here, it's not so evident which conditions should be added to prevent
unwanted interaction. Or, even
if you could, it would not be the best approach to mix the two business
logics...
In this case, there is a feature called *@propertyReactive* which I strongly
invite you to look up in the
manual AFTER you're feeling completely comfortable with the basic behaviour.
Best
Davide
p.a. drools.halt is only used in combination with fireUnitlHalt(), which
means that the engine will not
wait for an explicit command to fire the active rules. It's a global
behaviour that shuts down the
engine, so it's not recommended for loop control.

[rules-users] Noob desperately needing help
So, we have a massive web-based application with a rules engine powered by drools 4.0.7...I have a time-based rule that fires, executes about 80% of the java code, and then just stops. No error, no exception, no nothing...it just stops. Until I restart the node, all rules processing is suspended. I've let this process run for 24 hours without intervention, but it really is hung. And I know it's not in a loop, as I'm outputting console messages, and I know the exact line that the app is hanging on. I have tried upgrading to drools 5.4, but we didn't write the kernel of the rules engine, and I'm not really in the mood to deal with re-writing it, unless I absolutely have to. This is the first time I've ever seen anything like this, and this app has been running for 4 years with no rules-engine issues. We use it everywherewe are an EMS research organization supporting 3 states, and the application uses the rules engine to determine state-based EMS logic. We also use it as a timing trigger to email notifications to various EMS personnel to notify them of hospital facility closings, bed availability, etc. I have absolutely no idea what the problem is, or how to present it to the mailing list users in a way that might identify what the issue really is...so anyone who is game to help, ask me questions, and I'll answer them as best I can.
