[rules-users] Wait state constriant

Can anyone tell me what's wrong with this wait state constraint? System.currentTimeMillis() = (startWait + 3000) The exception I'm getting ist: [5,33]: [ERR 102] Line 5:33 mismatched input '=' expecting 'then' in rule RuleFlow-Milestone-drools.test.timer-6 but I don't think that is really getting

Re: [rules-users] Drools Flow

what are the condition from both rules? Can you share with us your processes definitions? did you check the process ids? Greetings 2010/7/22 santosh mukherjee sam.sensat...@gmail.com Hi, My rule file is like this: rule1: when something then start process(p1); rule2: when something

Re: [rules-users] Drools Integration

Hi, I am trying to integrate Drools with Apama. I have Apama installed and want to pass the events mathched through Apama into Drools. Need help as to how to proceed doing this. Basically I want that whenever a certain event matches and is caught by Apama. I want to send it to the drl files which

[rules-users] Problem with DRL language/ XLS decision tables.

Hello, I have a problem with defining rules. I insert many, many objects (facts) to ksession object (StatefulKnowledgeSession). I want to fire rules for *all*of them(facts), but I want to fire only one rule from all rules for each one fact(not always this same rule is fired, because I use

Re: [rules-users] Problem with DRL language/ XLS decision tables.

You could always have a pool of StatefulSessions that you reuse. (This would allow you to run concurrently in multiple threads as well.)  As long as these billions of facts don't need to interact that'll work fine.  However I'd suggest that you try the rule latch method that Thomas suggested. 

Re: [rules-users] Wait state constriant

Thanks for the reply. Just for the records: Chapter 3.5 of the Drools Flow User Guide says that there are two kinds of constraints: (a) code constraints and (b) rule constraints, where code constraints are boolean expressions. So wait states obviously don't support code constraints... correct?

Re: [rules-users] Problem with DRL language/ XLS decision tables.

Thanks for reacting ;) I did some simulations, and after them, I want of course to parallelize this process of processing 2 billions facts. But as far as I wrote, Drools engine, can't do this. And I have to create threads manually in application (with pool of sessions). Am I right? Tuning number

Re: [rules-users] Problem with DRL language/ XLS decision tables.

Considering that googling on rule latch will return this thread on gmane as the 2nd link, you might find research difficult. :)  I think Tom coined that term in this context, but it fits.  The basic idea is that you use an object as an indicator of what processing has happened, and whether or

Reto, This seems to be a conflict with similar actions in different processes overriding each other. I'll take a look at this and try to fix it asap, and keep you updated. Kris Quoting retoy reto.lampre...@allianz-suisse.ch: Hi Kris Here is a small project which demonstrates a similar

Re: [rules-users] Deserialization Error from Designer when Process Opened in Gunvor

Hi, Regarding the designer integration, it is probably important to know that Oryx is still using the BPMN2 beta 1 format, while Drools Flow has already updated to a more recent BPMN2 format. As a result, you probably can't open the processes that are generated by the Drools Flow graphical

Re: [rules-users] Wait state constriant

Reto, State nodes only support rule constraints. The reason is that a constraint in a wait state should be continuously evaluated (while the state is active), and the only way to do that efficiently is to use a rule for that (as that is basically what a rules engine is good at). I know the docs

[rules-users] StackOverflowError when serializing KnowledgeBase

Hello, After adding a few hundred rules, and with the same code, KnowledgeBase serialization has started to generate StackOverflowError. I have increased the VM stack size as a workaround, but I was hoping to implement something more robust. I specifically need to serialize the KnowledgeBase,
