[rules-users] Why this rule did't work?
I'm trying to formulate a condition like: package com.sample import org.hibernate.Session; import com.sample.entity.TempEntity; global java.util.List myGlobalList; rule Hello World when $hibernateSession : Session(); $tmp1 :TempEntity($bin1 :bin) from $hibernateSession.createQuery(from TempEntity).list() $tmp2 : TempEntity($bin2 : bin) from myGlobalList //eval($bin == ((TempEntity)(myGlobalList.get(0))).getBin()) eval($bin1 == $bin2) then System.out.println(success); end I'm trying to find an Entity by bin from DB. there is only one entity in the myGlobalList. NO complie error but it shows the following: log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment). log4j:WARN Please initialize the log4j system properly. Hibernate: select tempentity0_.bin as bin0_, tempentity0_.bank_name as bank2_0_, tempentity0_.bank_id as bank3_0_, tempentity0_.card_name as card4_0_, tempentity0_.card_length as card5_0_, tempentity0_.card_type as card6_0_ from bin tempentity0_ what should I do if i want this rule works? -- View this message in context: http://www.nabble.com/Why-this-rule-did%27t-work--tp25218669p25218669.html Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Conditional 'not' invalid for event streams?
Hi Barry, Yes, it would be awesome to add it to drools-contrib code. I am traveling to JBoss World tomorrow, but when I am back I will take a look at your code. Also, please send all the feedback you have on this experience my way. Drools Expert is a mature engine, but Fusion is brand new, so we have a lot to do still, and having external views on the project is a great way to guide us through development. Thanks, Edson 2009/8/31 Barry Kaplan grou...@memelet.com Good evening Edson, I am using insert time -- the event classes have no timestamps properties. BTW, I have git project with all this code, but I don't think this last bit is pushed yet... (http://github.com/memelet/drools-esper/tree/master). Maybe once I've gotten thru the pattersn we can add it to drools-contrib as additional examples? -barry -- View this message in context: http://www.nabble.com/Conditional-%27not%27-invalid-for-event-streams--tp25217095p25218351.html Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- Edson Tirelli JBoss Drools Core Development JBoss by Red Hat @ www.jboss.com ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Maven Plugin to build pkg files
Hi all. I wonder if there exists a maven plugin to build pkg files out of the rule base during the maven packaging. Because we dont use the Guvnor repository in this project and I want to package the pkg files with the overall ear. I searched a bit, but didnt found anything Okay, not hard to write ourself, but would be nicer to reuse existing stuff Thanks Bernd ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hi, I need to calculate the min time for a set of jobs inserted in working mermory to know wich job is going to be finished first.

Re: [rules-users] Calculating minimal value for a group of facts
You can use a collect statement to get all of the Job objects. $list : ArrayList() from collect ( Job() ) alternatively if all that your service method call is doing is comparing the values of a field in a list of Job objects, there are ways to do that without the eval when $shortest : Job ( $min : min) not Job(min $min) then go go go!

Re: [rules-users] Guvnor fails to vaildate rule, though same rule compiles and run successfully when compiled command line with ANT.
Since no replies as of yet I've done some more testing and have some more detail.. this seems to be a bug but I could use some eyes on this as I'm a drools newbie... I now have two rules in a clean project in Guvnor... First rule like this validates fine: when $root : Root() then logger.debug(PNRLookupRequest - Start); Second rule is as follows: when /* $root : Root(); $id : IdentityRequest() from $root; */ Root($id:identityRequest != null) then logger.debug(PNRLookupRequest - Check Data); When I attempt to validate it generates a fatal error and logs the following in the tomcat catalina.log: ERROR 31-08 13:49:51,656 (RepositoryServiceServlet.java:doUnexpectedFailure:66) java.lang.reflect.InvocationTargetException com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract org.drools.guvnor.client.rpc.BuilderResult[] org.drools.guvnor.client.rpc.RepositoryService.buildAsset(org.drools.guvnor.client.rpc.RuleAsset) throws com.google.gwt.user.client.rpc.SerializableException' threw an unexpected exception: java.lang.reflect.InvocationTargetException at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java:360) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:546) at com.google.gwt.user.server.rpc.RemoteServiceServlet.processCall(RemoteServiceServlet.java:164) at com.google.gwt.user.server.rpc.RemoteServiceServlet.doPost(RemoteServiceServlet.java:86) ... at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java:527) ... 21 more Caused by: java.lang.LinkageError: duplicate class definition: org/drools/base/com/netid/idia/model/natal/rootIdentityRequest/Root274270528$getIdentityRequest at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at org.drools.base.ClassFieldAccessorCache$ByteArrayClassLoader.defineClass(ClassFieldAccessorCache.java:367) If modify the rule to replace the failing when clause with the commented out block it then validates fine.. These same rules compile fine through ANT.. any known bugs in Guvnor that would cause this? Codedrop wrote: Reposting as last message was unledgible. Recently upgraded from Drools 4.0.7 to 5.1.0 and have imported our rules into Guvnor.

There is a valid getter in the java file and guvnor displays identityRequest in the list of attributes for ‘Root’. Oddly, if I change the when clause to be Root(this.identityRequest != null) it validates fine.

[rules-users] Why so many ACTIVATION/DEACTIVATION events?
We have a fairly complex object model, but we're still puzzled - I thought that the definition of Activation was that the data matched on all conditions of a rule, and therefore the rule was entered into the agenda (activated). If that is true, I cannot figure out why we're experiencing this. As our number of rules increases, we're seeing exponential increases in repetitive activation/deactivation pairs, even on rules where we know the data does not match the conditions. Example: The following rule (abbreviated here) creates an object of type PolicySet if there are none that match the conditions. I would expect this rule to activate once, then fire, wherein the matching PolicySet is created, and then never activate again since the absence of a matching PolicySet object is never again true. However, in a rule base of ~4,000 rules, we see this rule activating 975 times and deactivating 975 times. This is just one example - nearly all our rules do this, and it is seriously impacting decisioning performance. Have I misunderstood the meaning of activation? Can anyone help me understand this? rule RS6090.1.12_RF7007_50001012 when LendingProduct ( $exitStrategyType1 : exitStrategyType ) Features ( $lienPriority1 : lienPriority ) DecisionResultsInfo ( $dealRiskCategory1 : dealRiskCategory ) TransactionDetail ( $parentTransactionDetail1Id : myId ) not ( PolicySet ( $parentPolicySet_1_Id : myId, parentId == $parentTransactionDetail1Id ) and PolicySetIdentifier ( parentId == $parentPolicySet_1_Id , lienPriority == $lienPriority1 , exitStrategyType == $exitStrategyType1 , dealRiskCategory == $dealRiskCategory1) ) then // Content removed... rule creates the policy set and the policy set identifier, and initializes all appropriate elements // After doing so, why does it activate/deactivate 1800+ times in a rule base of 4000 rules? System.out.println(6090 fired.); End Thanks. Tom Murphy Business Process Consultant Wells Fargo HCFG - CORE Deal Decisioning Platform 800 S.
