Re: [rules-users] String as an argument

Khalil, Drools does support strings, as it should. Something else is going on there. I assume you have a proper: public String getId() method. All I can suggest is for you to open a jira and attach a test case to reproduce the problem. Edson 2010/2/5 Khalil Hafsi > Hi Guys, > > I

Re: [rules-users] RES: Problem with proxy objects

Rogerio, I don't know what javassist does with your class... if it preserves the object hierarchy (what I think it probably does), then it must work. The only way to find out the reason is with an isolated test case and do some debugging to understand why it is not failing the isAssignableFr

[rules-users] String as an argument

Hi Guys, I am using Drools fusion 5, My "Event" class // @role (event) // has a string parameter "id" , however if I try to do : // Rule .. .. $a : Event(id == "a") then //do something end It complains about "Conversion from double is not supported in java.lang.String" , is there any way to ma

Re: [rules-users] Drools not returning

Happens to me all the time, but I'm a real novice at rules. I find it easiest to start with helloworld level rulesets until I can fully understand how a ruleset can stay in an infinite loop by creating effects which in turn create more effects. It's a feature, not a bug. :) 2010/2/5 Edson Tirelli

[rules-users] SWRL to Drools transformation

Hi, I wonder if anyone has worked on a tranformation of SWRL rules (or RuleML) to Drools? The use case is this: I'm loading OWL ontology to Drools (as triples) and want to use Drools for infererence based on the SWRL definitions. It sounds straignt forward, I wonder if it's been done yet. Thanks

Re: [rules-users] Drools not returning

Hehe, not normal at all. :) You probably have an infinite loop in your rules. Try using the audit log to track what is going on, and the fireAllRules( int maxFirings ) parameter to prevent it from looping forever. Edson 2010/2/5 Khalil Hafsi > Hi Guys, > > I am using Drools fusion 5 , is

[rules-users] RES: Problem with proxy objects

I think you didn't understand my problem. I don't have any problem related to Java arrays. My problem is drools is not working with proxy objects. I am executing drools rules with one javassist object (package.MyClass_$$_javassist_2) and drools is not recognizing this object as package.MyClass a

Hi Guys, I am using Drools fusion 5 , is it actually normal that the engine does not terminate ? I am using fireallRules. Thanks, k- ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Problem with proxy objects

Unfortunately a Java array does not implement the Iterable interface, so we have to use the JDK converter method Arrays.asList(...). Try ksession.execute( Arrays.asList( new Object[] { myObject} ) ); -W 2010/2/5 Rogerio Baldini : > Hi guys, > > > > I am trying to execute rules passing a pro

[rules-users] Problem with proxy objects

Hi guys, I am trying to execute rules passing a proxy object to it. The object myObject is a javassist proxy object: package.MyClass_$$_javassist_2 Properties p = new Properties(); p.put("url", "http://localhost:8090/drools-guvnor/org.drools.guvnor.Guvnor/package/pacote /LATEST");

[rules-users] complex rule conditions

Hi, I want to use some "complex" conditions on the lhs of a rule. Following the example in the drools-expert docu: Person( girlAge : age, sex = "F" ) Person( eval( age == girlAge + 2 ), sex = 'M' ) I have try the following rule: rule "detect stop of cars" when p1:PositionReportEven

[rules-users] Drools planner & Scala

Hello, I'm using Planner in a Scala program and it almost works without problems; the only one is in implementing the Solution interface, as it uses raw (erased) version of Score, which is normally generic (Score). Scala generally doesn't like raw types and in most cases it's impossible to ext
