Re: [rules-users] Guvnor 5.4 CR1 role based authentication with JBossAS 7
Any ideas guys? This is making me believe there is something mixing with bean
configuration. When I uncommented ...

[rules-users] Guvnor - support for custom file extensions
Hi! I need to extend Guvnor to support custom file extensions for BPMN processes. So instead of using /.bpmn/ or /.bpmn2/ we need to use our own file extensions. At the moment Guvnor just assumes them the to be /Other assets/ and ignores them when building a package. I plan to change Guvnor source to achieve this. I would appreciate if I get some guidelines from dev-team, what classes do I have to change. Since you have recently been adding support for /.bpmn2/ extension, I guess you could give me some hints. I found out that I have to add my extensions to /org.drools.guvnor.client.common.AssetFormats/, change /org.drools.guvnor.server.builder.AssetItemValidator/ and /org.drools.guvnor.server.verification.AssetVerifier/ . Is there something else?

Re: [rules-users] agenda-groups
I am not currently using agenda-groups. I believe my issue right now is one of thread safety. A little background: I currently have a thread pulling messages from a database running on the main thread. In several other threads, I have drools session being fired every so often. It appears that there may be a some type of deadlock caused by invoking fireAllRules on one thread, while another is trying to insert. I am working through right now to debug the issue. Has anyone else experienced this issue? Vincent Legendre wrote I am having an issue where I have a catch all retraction rule setup as the lowest salience. Not sure to understand that (note that I am not english native ...) I see activations created for the facts but they are never fired. Any thoughts on why this may happen? Send some rules. Activations never fired is just too vague to have a single answer. If you use agenda groups, may be that the group is simply not on focus ... Add a first rule that set the focus, or set auto-focus for all your low salience rules, or don't set agenda group for them (their group will be the MAIN group). The session is run on a separate thread with fireAllRules called every 1/2 second. I have tried syncronizing inserts on the session so that thread would not be in the middle of firing when new facts come in but that does not seem to do anything Why not using fireUntilHalt instead ? Run your session.fireUntilHalt in a separate thread, and insert things in that session. insert (or update or retract) will wake up the session.

[rules-users] NoClassDefFoundError: org/eclipse/core/runtime/Plugin in fresh Drools IDE install
Hi, I've created a new Drools dev setup with the latest version of the IDE (problem exists in Helios also), but having an issue running projects. Have stripped this down, and the problem exists even with a brand new project created with the Drools wizard. When running even the base DroolsTest in a default project I get the following error.

Re: [rules-users] using Drools global variables inside operator timer(int: variable name s)
Hi, there's a recently added feature that should allow you to do so. It's the expr mode for timers: timer( expr: delay MVEL expr here, optional period MVEL expr here ; ) It supports up to two valid MVEL expressions, which resolve to delay and period. They need to be separated by a , if you use both, and need at ; at the end. The expressions need to evaluate to a timer String or to a long (assumed to be milliseconds). Locally bound variables are known to work, globals should be usable too Cheers, Davide -- View this message in context: http://drools.46999.n3.nabble.com/using-Drools-global-variables-inside-operator-timer-int-variable-name-s-tp3950828p3971912.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

Yes, I'd say that's more like it. If these zillions of facts aren't related, they can be processed by disjoint sessions. So, if you want to feed more than one CPU, run several sessions like that. It might be desirable to have small batches of facts inserted and processed by a single call. You should know whether there is a way to do that... -W gboro54 wrote The point is to be able to stream a large volume of messages into the rule session without tying up that thread. In addition I don't want there to be millions of messages in a session at a given point, thus the point of executing the rules on a different thread while inserting facts from another. laune wrote What about executing insert(s) followed by fireAllRules() in one thread? -W On 08/05/2012, gboro54 lt;gboro54@gt; wrote: What do you recommend? firUntilHalt seems to get locked out after sometime... I am running out of ideas and have posted this question before.

I believe my issue right now is one of thread safety. A little background: I currently have a thread pulling messages from a database running on the main thread. In several other threads, I have drools session being fired every so often. It appears that there may be a some type of deadlock caused by invoking fireAllRules on one thread, while another is trying to insert. I am working through right now to debug the issue. Has anyone else experienced this issue? Vincent Legendre wrote I am having an issue where I have a catch all retraction rule setup as the lowest salience. Not sure to understand that (note that I am not english native ...) I see activations created for the facts but they are never fired. Any thoughts on why this may happen? Send some rules. Activations never fired is just too vague to have a single answer. If you use agenda groups, may be that the group is simply not on focus ... Add a first rule that set the focus, or set auto-focus for all your low salience rules, or don't set agenda group for them (their group will be the MAIN group). The session is run on a separate thread with fireAllRules called every 1/2 second. I have tried syncronizing inserts on the session so that thread would not be in the middle of firing when new facts come in but that does not seem to do anything Why not using fireUntilHalt instead ? Run your session.fireUntilHalt in a separate thread, and insert things in that session. insert (or update or retract) will wake up the session.

[rules-users] Complex pattern
Hi there, I've been struggling for almost a day now, trying to create a pattern that goes something as follows (notice it doesn't compile): rule Complex pattern when $triviaResponse : TriviaResponseArrived($matchers: matchers) $subscriptions : ArrayList() from collect ( $s: Subscription() $lock: Lock(object == $s) exists SubscriptionMatcher(matches($s)) from $matchers ) then logger.info(NO TRANSACTION, Selected subscriptions + $subscriptions); end where TriviaResponseArrived, contains a List of SubscriptionMatchers (a simple object which just returns true or false when its matches method is called). Upon receiving this TriviaResponseArrived fact, I'm trying to select all subscriptions from the working memory, for which there is also a Lock, and that there exists a matcher within the matchers list that validates it. To sum up, all subscriptions in the list subscription, should be locked, and matched by a matcher in the triviaResponseArrived fact. The closes I've managed to come is: rule Complex pattern when $triviaResponse : TriviaResponseArrived($matchers: matchers) $subscription : Subscription() $lock: Lock(object == $subscription) exists SubscriptionMatcher(matches($subscription)) from $matchers then logger.info(NO TRANSACTION, Subscription + $subscription); end Which is not quite right, since I need to process all the subscription that match the above logic at once. As always, all help is really appreciated. Thanks. Cheers. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Drools integration with Spring

I need help in following items: 1. how to integrate the drools with my Spring application. 2. I have a scenario like i need to write different rules file for different beans ... say i have two beans (Employee, Department) to validate for which i have written two rules file say EmployeeRule.drl and DepartmentRule.drl files. i have a common method where i am passing the object(either employee or Department) that need to be checked. In this case how will i add different drl file in KnowledgeBuilder. Like to validate Employee bean i need to add EmployeeRule.drl file and to validate Department bean i need to add DepartmentRule.drl file.
