Would like to know about a coming Workshop/Training/Seminar in Drools/Guvnor

by ggeda

Hi All, I am looking for a Workshop/Training/Seminar in Drools/Guvnor in United States. I am doing a google search but thought word of mouth from smart people in this group is better. Please let me know if you have any information on this. Thanks, Genene -- View this message in context: http://drools.46999.n3.nabble.com/Would-like-to-know-about-a-coming-Works...

How to use my own rule semantics?

by andrew8666

I am making some kind of expert system in drools. It will be based on fuzzy logic. I have a analysis which describes what semantics to use. Problem is that i don't know how to rewrite this semantics to drools. Look: x ∧ y = min{x,y} x ∨ y = max{x,y} x → y = 1 for x <= y, y for x > y Any hint will be appreciated. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-use-my-own-rule-semantics-tp4025...

Fully qualified name for generated classes

by Lance Leverich

What would be the fully qualified name for a generated class, that is based upon a fact type (for example a type named "Foo") that is defined inside a declarative model? How is the fully qualified name affected if the model resides in the Global Area, and is imported into multiple packages? The reason for my question is that I have the following issue: In the Global Area, I have a declarative model (named MyModel) with a definition like... declare Foo bar: String version: String end In a package (com.mypkg.a), I have imported MyModel from the Global Area. I have a rule like... rule "myRuleA" ruleflow-group "firstGroup" when not Foo( bar=="bar" ) then Foo fact = new Foo(); fact.setBar("bar"); fact.setVersion("1"); insert(fact); In another package (com.mypkg.b), I have also imported MyModel from the Global Area. I have a rule like rule "myRuleB" ruleflow-group "secondGroup" when Foo() then System.out.println("got at least one Foo"); Looking at logs, the rule myRuleA fires as is appropriate; however, the rule myRuleB does not fire, even though both ruleflow groups are represented in the ruleflow. I have verified that both of the ruleflow groups are activated, using the logs. My best guess at this point is that the class generated for fact type Foo is different for each package. So, how can I make sure that I am instantiating and checking for the same type across packages? Lance Leverich

temporal reasoning/drools fusion: basic question

by amarok

Does fusion support temporal reasoning on futur events? E.g. I want to define rules like the following: If within 5 minutes after Event X there is NOT an Event Y Then do [...] This rule would then be "initiated" when an Event X occurs, and would be "fired" when within the next 5 minutes no Event Y follows. If this does not work with fusion, what would you recommend? If it does, could someone post a very simple .drl example for such a rule? -- View this message in context: http://drools.46999.n3.nabble.com/temporal-reasoning-drools-fusion-basic-...
