[rules-users] Use of DroolsManagementAgentMBean

Hello all, I need to grab all the information/statistics after firing all the rules. It is observed that the same can be achieved by different event listeners in drools. But I don't want to use listeners, instead I need all the information after firing all the rules. Going through the Drools API,

[rules-users] Some doubts on Guvnor

Hello! So, let'me explain what is happening first... I'm developing a project based on seam 2.2.0, and we used to have guvnor (5.0.1) working perfectly. So, suddenly I decided it was time to move on and start using the newest version (5.1.1, i guess). Made a backup of the older version, configur

Re: [rules-users] Why Using "from" Always Return A New Fact?

Yes, but just to clarify: as it is now, we parse semantic blocks of code like RHS as a black box (chunk if you will) and then re-parse that with the appropriate dialect parser (like java). Same for expressions in the rule, that we chunk and delegate to MVEL. That is why, for instance, to write a

Re: [rules-users] Why Using "from" Always Return A New Fact?

Yes, it might be different from version to version as we improve the overall algorithm. The reason for the different behavior is that under Drools 5.0 (and in most rule engines out there), every modify is just a retract+assert. So, the different fact handles would prevent the proper normalizatio

When you say "owning 100% of the language syntax" does that include the RHS? Just curious. GreG On Jan 19, 2011, at 22:04, Edson Tirelli wrote: > As of Drools 5.1.1, drools looks at the expression in "from" as a > black box. Every time it is executed, drools creates a new fact handle > to w

[rules-users] Drools with Hibernate, with dynamic types

Hi, I'm gathering the requirements for an odd system project, and I have a design idea that is centered around Drools. I'd like to hear everyones opinion. The project is in a really early stage of conceptual analysis, and I'm also near the start on the winding road exploring Drools. The requirem

Re: [rules-users] How to write a rule that fires when it matches against specific facts in working memory.

I understand this so that there must be *exactly* 2 Option facts, and therefore: $o1: Option (code == "P1") $o2: Option (code == "P2") not Option( this != $o1, this != $o2 ) On 20 January 2011 14:33, Bruno Freudensprung wrote: > > Hello, > > Maybe could you try the following rule? > > rule "Mat

Re: [rules-users] Drools repository and accessing the rules engine from vb.net

I have to make a correction here. The KnowledgeAgent only provides a way to maintain a knowledge base updated. It doesn't have any capability to "execute" rules. A possible solution to execute rules from .NET could be the use of Drools Server ( http://hudson.jboss.org/hudson/job/drools/lastSuccessf

Re: [rules-users] Salience

Another way is to have a helper fact to help with the logic. In our case we have an "Affirmation" class with the tuple (name, subject, value). However salience does still have a purpose and is still a useful and required tool to order groups of rules - you just have to make sure you don't abuse i
