accumulate Functions with self coded classes as result type

by Andre

i implemented an accumulate function which uses Datatypes, which i coded my self , see example the function return a list of ResourceMatch Objects, but when i try access that objects i get an NullPointerrException (nothing more) (yes i imported that class in the DRL) so it seems that there has to be some kind of registration, so drools, can handle these objectsm right ? or what did i forget? rule "Request counting analysed Resources By Id" when $list: List() from accumulate($neu : RequestCtx() over window:time(1m),countMatchingAnalysedResourcesInRequest($neu) ) ResourceMatch( $id: uri.toString(), count > 1 ) from $list then System.out.println( "Id " + $id + ": " ); System.out.println("Request counting Resources By Id Rule Workss"); channels["AuthZBlocking"].send(new ItemCacheEntry(new Item((String)$id), new Date(System.currentTimeMillis()+ 8000))); end -- View this message in context: http://drools.46999.n3.nabble.com/accumulate-Functions-with-self-coded-cl...

Drools firing wrong rules

by pamerida

Hi everyone, I have a couple of rules, I just want to show a message when one of the fields is null and heres my code: 21. | rule 'rule1' 22. | salience 9990 23. | when 24. | Cuscar(bgm.size > 0 && bgm[0].c1001== null ); 25. | then 26. | logger.log("Rule 1 activated"); 27. | 28. | end 29. | 30. | rule 'rule2' 31. | salience 9970 32. | when 33. | Cuscar(bgm.size > 0 && bgm[0].c1004== null ); 34. | then 35. | logger.log("Rule 2 activated"); 36. | 37. | end And here's the result: Scenario #1 http://drools.46999.n3.nabble.com/file/n3160376/debug2.jpg with this values when I call fire all rules I dont get any message (its ok because none of the elements is null) Scenario #2 http://drools.46999.n3.nabble.com/file/n3160376/debug1.jpg with this values when I call fire all rules both rules are fired so i get both messages "Rule 1 activated" and "Rule 2 activated" (Incorrect - it should only fire rule number 1 cause only the element c1001 is null) Scenario #3 http://drools.46999.n3.nabble.com/file/n3160376/debug3.jpg with this values when I call fire all rules I dont get any message (Incorrect - it should activate rule number 2) This is my model: http://drools.46999.n3.nabble.com/file/n3160376/rules-drools-model-1.0.0-... rules-drools-model-1.0.0-SNAPSHOT-jar-with-dependencies.jar Can anybody help me please?, I dont know what am I doing wrong, thank you very much :) .... -- View this message in context: http://drools.46999.n3.nabble.com/Drools-firing-wrong-rules-tp3160376p316...

Drools-API in 5.2.0.FINAL?

by Andrew Waterman

Hi, I was trying to upgrade my dependencies from 5.2.0.M2 to 5.2.0.Final and I noticed that there doesn't seem to be a "final" build for the drools-api module: https://repository.jboss.org/nexus/content/groups/public-jboss/org/drools... I'm also not seeing any 5.3 updates in that repository. Am I missing something? Did this module go away? Thanks!

Is there any way to compress (gzip) the rules package to optimize network traffic between server and agent?

by tarley.lana

We have a drools application composed of almost 1000 rules. The rules deployment package has almost 8MB and we need to distribute it over a 100 Kbps network for offline use on some client machines. If we could zip this package, it would require only 237Kbytes (instead 8MB). It seems, however, the class org.drools.agent.impl.KnowledgeAgentImpl doesn't support gzip compression. Is it right? Is there any workaround for this problem? Thanks in advance. -- View this message in context: http://drools.46999.n3.nabble.com/Is-there-any-way-to-compress-gzip-the-r...

Any suggestions to implement exclusions and avoid update

by Wishing Carebear

Hi, Below are 2 rules, rule1 has higher precedence than rule2. Rule2 should not execute if Rule 1 executes. 1) One way to get this working is to check the null value. 2) If the update is not called, the Rule2 gets executed using the previous null value of potentialTheftRating. Is there any other way to implement this requirement. rule "Rule 1 PotentialTheft0" ruleflow-group "TheftRating0" salience 10 no-loop lock-on-active when $client : Client() $policy : Service(productType == "Vehicle Insurance") from $client.service $car : Vehicle(potentialTheftRating == null, vehicleType == vehicleTypeType.CAR, convertible == Boolean.TRUE) from $policy.vehicle then modify ($car) { setPotentialTheftRating( potentialTheftRatingType.HIGH ) } update($client); end rule "Rule2 PotentialTheft0" ruleflow-group "TheftRating0" no-loop lock-on-active when $client : Client() $policy : Service(productType == "Vehicle Insurance") from $client.service $car : Vehicle(potentialTheftRating == null,vehicleType == vehicleTypeType.CAR, price >= 20000, price <= 45000, highTheftProbabilty == Boolean.FALSE ) from $policy.vehicle then modify ($car) { setPotentialTheftRating( potentialTheftRatingType.MODERATE ) } update($client); end

Drools 5.2.0 does not create a new task for the next HumanTask when I complete the first HumanTask

by maxnguyen

I have a flow with two Human Task nodes: Start -> Review Loan -> Approve Loan -> End. With Drools 5.1.1, when I complete "Review Loan", a new task is created for "Approval Loan" automatically and the process waits at this node. But with Drools 5.2.0 and Jbpm 5.1.0, no task is created for "Approval Loan" when I complete "Review Loan". Any help is much appreciated. -- View this message in context: http://drools.46999.n3.nabble.com/Drools-5-2-0-does-not-create-a-new-task...

Writting a fusion query with specific time intervals

by Amila Suriarachchi

As I understood Drools fusion supports sliding windows which can either time based on message length based. But can I write a query with specific time intervals? For an example Lets say my CEP engine recive events which has order value. Now I want to fire an event if the orders within 8.00 am to 9.00 am have less than $40000. In generally firing an event if there are less that $40000 total order value within any working hour (i.e 8.00 am 5.00 pm) is it possible to do this? -- View this message in context: http://drools.46999.n3.nabble.com/Writting-a-fusion-query-with-specific-t...

Starting Guvnor in Eclipse

by Justin Case

Hi all, any Eclipse users around here? I have followed the instructions here: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/READ... for Eclipse Helios+EGit+m2eclipse. I downloaded 5.2.0.Final from https://github.com/droolsjbpm/guvnor.git, imported all Maven projects it could find in the directory (except guvnor-docs which misses something and I didn't care). The Guvnor application will start in development mode, but: - Firefox is causing often 100% CPU with it (might be the development mode) - Eclipse Development Mode view shows LOTS of errors like this: [ERROR] [org.drools.guvnor.Guvnor] - Errors in 'file:/C:/PocDev/GitHome/git/guvnor/droolsjbpm-ide-common/src/test/java/org/drools/ide/common/client/modeldriven/SuggestionCompletionEngineTest.java' [ERROR] [org.drools.guvnor.Guvnor] - Line 47: No source code is available for type org.drools.ide.common.server.rules.SuggestionCompletionLoader; did you forget to inherit a required module? [ERROR] [org.drools.guvnor.Guvnor] - Line 49: No source code is available for type java.util.jar.JarInputStream; did you forget to inherit a required module? Again, one can work also like this but seeing hundreds of errors is not helping at all when I try to tinker with something somewhere. Plus there's the 100% CPU thing... where and what should I inherit more than Maven is configured already to inherit? Tinkering around: - I set all other projects as dependencies - I set to export all sources from all projects (but there it bitches also about missing java.util sources, who cares about these?)... - added all these sources to the run configuration nothing changed, I still have the above errors from both system libraries AND project dependencies. Or do I experience the problem mentioned in this message? http://markmail.org/message/h52xvo4j52msambe#query:+page:1+mid:lg4mlgiof4... Thanks for any hints, JC

AgendaGroup and AgendaFilter

by Saleem Lakhani

Hi, Previous Code from drools 3.x: Below is an example of overridden method in a class that implemented org.drools.spi.AgendaFilter public boolean accept(Activation activation) { boolean evaluateRule = false; String agendaGroup = activation.getRule().getAgendaGroup(); if (functionalArea.equalsIgnoreCase(agendaGroup) { evaluateRule = true; } return evaluateRule; } Drools 5.x Now I have changed the implementation to org.drools.runtime.rule.AgendaFilter How do I re-write the bold-italic line inside the method when variable activation is now an instance of org.drools.runtime.rule.Activation; It doesn't support activation.getRule().getAgendaGroup(); Thanks, saleem
