Re: [rules-users] dependency issue after upgrading to 4.0.0 from MR3 with maven2?

Yes. The same way that the order in SQL statements matter. So always write more constraining patterns first and you will get huge performance benefits. []s Edson 2007/7/26, Ronald R.

[rules-users] Re: Odd static inner class behavior
Edson, That certainly makes sense. However I'm fairly certain that in referencing the inner class in rule definition, I always qualified it with the outer class name, ie: DataClass.AlternativeKey() or AnotherClass.AlternativeKey() I appreciate your explaination of the merge process. Rather than have you spend any more time on this, I'll try to put together a test case to ensure I was seeing the behavior I thought I was seeing. I probably won't get around to this until tonight or the weekend. If I was mistaken, I'll let you (and the mailing list) know. If I was not, would you like me to open a JIRA with the attached test case? I would assume that if the inner classes contain the qualified name that the engine should be able to handle that? Thanks, Eric Edson Tirelli wrote: Eric, Thanks, I understand now. What happens is that if both DRL files declare the same package name, all their contents will be merged. It means that you would end up with both imports in the same namespace: import com.company.DataClass.AlternativeKey; import com.company.AnotherClass.AlternativeKey; And so the engine will raise an error saying that it does not know which one you are refering to when you write simply: AlternativeKey I think the engine behavior is correct, since the idea of loading two different files with the same name space into the same package builder is to merge them, or even replace (update) that eventually have the same name.

Re: [rules-users] Trying to create a restriction for an empty restriction error
Yuri, We support - for backward compatibility and I confess I haven't seen this error before. I guess it may be complaining about the variable binding: $age : age - (Math.abs($age - c1.age) 10), Anyway, if you can please open a JIRA for that. An yes, we prefer to not use - anymore, so if you are able to change this during your upgrade, then it is better to simply use the eval keyword instead of the -. Example: c2:Child( eval(Math.abs(age - c1.age) 10), ...) Note that if that is the only place where you use the age field, the binding is automatically created for you. You don't need to do it explicitly anymore. If you need the binding for other purposes, you can do a regular binding: c2:Child( $age : age, eval(Math.abs($age - c1.age) 10), ...) Regarding your second questions, the answer is yes. We now support totally nestable and || as constraints and restriction connectors. So: p2: Person( (sex == M p1.sex == F) || (sex == F p1.sex == M) ) () are optional and has higher priority than ||. We already updated docs for such things in the manual. I would like to ask you to read and please provide feedback and even patches for parts of the text that eventually are not clear: http://labs.jboss.com/file-access/default/members/drools/freezone/docs/4.0.0.13773GA/html/index.html Section 6.5.2.

Re: [rules-users] processBuilder constructor
You shouldn't really access the ProcessBuilder directly anymore, we've added support in the PackageBuilder for that (similar to rules, decision tables, etc.): PackageBuilder.addRuleFlow(Reader) If you want to access ProcessBuilder directly, you can just provide an empty PackageBuilder, but it seems unlikely that you don't want to add any rules, as the ruleflows main purpose is to manage the evaluation of rulesets. The ProcessBuilder requires access to a PackageBuilder as it internally also uses rules to control the ruleflow process execution.

[rules-users] [Newbie] Can't execute BRMS Discount insurance brokers tutorial
Hi all, I'm having troubles following the tutorial at 9.5.1 in Drools Documentation. At the point ...Import the demo business rules insurance repository file into BRMS, the compressed can be found at files folder in the demo project. I cannot find any files folder in http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-examples/drools-examples-brms/. I managed to import rules repository using repository_export.xml in http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-examples/drools-examples-brms/src/main/resources/ I can see package and rules correctly loaded in BRMS, but when i try to build binary package I get 16:37:25,203 INFO [STDOUT] ERROR 25-07 16:37:25,203 (ApplicationContext.java:log:660) Exception while dispatching incoming RPC call java.lang.IllegalArgumentException: Unable to handle the content type: dslr at org.drools.brms.server.contenthandler.ContentHandler.getHandler(ContentHandler.java:74).

Im not sure over a period of time if your objects would be released with a StatefulSession/WorkingMemory, would recommendyou soak test (test over a period of time with consistent l oad)But here is the possibility:Well the interface WorkinfgMemory -- extends -- Eventmanager which extends Serializable.You could try serializing the object, or query your WorkingMemory for its stateand save it to a database. Am assuming you are using StatefulSession so youwill have access to WorkingMemory. Conceptually I just think its worng to use a Rule Engine to persist state overa such a long period of time.

Re: [rules-users] Odd static inner class behavior
Eric, Thanks, I understand now. What happens is that if both DRL files declare the same package name, all their contents will be merged. It means that you would end up with both imports in the same namespace: import com.company.DataClass.AlternativeKey; import com.company.AnotherClass.AlternativeKey; And so the engine will raise an error saying that it does not know which one you are refering to when you write simply: AlternativeKey I think the engine behavior is correct, since the idea of loading two different files with the same name space into the same package builder is to merge them, or even replace (update) that eventually have the same name. What do you think? Edson 2007/7/26, Eric Miles [EMAIL PROTECTED]: Edson, I have since changed my schema but here was my issue: rule1.drl: import com.company.DataClass.AlternativeKey; import com.company.DataClass; rule Some rule when DataClass.AlternativeKey(someParm == true) then ... end Different drlf file: rule2.drl import com.company.AnotherClass.AlternativeKey; import com.company.AnotherClass; rule Another rule when AnotherClass.AlternativeKey(diffParm == 1) then ... end This was the gist of what I was doing. The outer classes' names were different, it was the INNER class of each of these classes that had the same name. I was actually getting compile errors on the import statements. Like I said, these rules worked fine if loaded separately, but once I tried to put them all int he same rule base, I was getting the import collision error. Later on this evening (when I'm not at work), I'll try to put together a small test case and upload it. In the meantime, you can look skim over this and let me know if something jumps out at you.

Re: [rules-users] problems using rule flow
So my question is, how can I say to the split node to consider the fact outgoing from the ruleFlowGroup1 and not a fact in the working memory In one of the future releases, we will add support for ruleflow 'variables' that can temporarly store some value so that it can be used by other rules or inside constraints (like a split in your example). For now you can simulate this by either using some dedicated Fact in your working memory or a global that can store this value.

[rules-users] Does when order matter?
All, I was wondering [and maybe this has be answered before] ,but does the order of the rules in the when clause matter? For example I have the following: rtvHeader : RtvHeader( headerRtvNumber : rtvNumber ) repaymentCode : RepaymentCode( actualCode : code, matchApprv != Y ) lineCharge : HeaderAdditionalCharge( rtvNumber == headerRtvNumber, originalRepaymentCode == actualCode ) In my case there is a higher likelihood that I will have more RepaymentCodes than RtvHeaders [1 of these guys] and likely less HeaderAdditionalCharge objects. So should the order be more like: rtvHeader : RtvHeader( headerRtvNumber : rtvNumber ) lineCharge : HeaderAdditionalCharge( rtvNumber == headerRtvNumber, originalRepaymentCode : originalRepaymentCode) repaymentCode : RepaymentCode( actualCode == originalRepaymentCode, matchApprv != Y ) Or does it not really matter?
