Re: [rules-users] Accepted idiom for binding variable to restriction?
Why not use from? The manual suggest this approach to reason over data that is not explicitly asserted in knowledge base. It seems to me that it fits best in the requirement of Laird. Please correct me if this is bad practice: $response: Response() $question: Question(ID == XYZ) from $response.question Is there some advantage/disadvantage on using 'from' instead of 'eval' in this case? Regards. Giovanni 2010/6/2 Edson Tirelli tire...@post.com Syntactically speaking, I don't think the eval is necessary: $response : Response( $question : question, question.ID == XYZ ) Behind the scenes Drools will still generate an eval to resolve the nested property constraint, but the rule stays simple to read and maintain. Edson 2010/6/2 Wolfgang Laun wolfgang.l...@gmail.com The inline eval constraint is what you want: a boolean expression, within parentheses. $response : Response( $question : question, eval(question.getID().equals( XYZ ) ) ) See the Drools Expert manual, section on Left Hand Side... -W On 1 June 2010 23:54, Laird Nelson ljnel...@gmail.com wrote: I have a fact that is inserted into my rule base. It is a Response. A Response has a Question that it is a response to. At the moment, the Question itself is not separately inserted into the knowledge base. I would ideally like to keep it this way. What's the best approach for binding variables to both the Response and its associated Question? That is, if the Question were inserted, it would be relatively easy: when $question : Question( ) $response : Response( question == $question ) ...but I'm finding myself somewhat confused how to extract a Question out of a Response, particularly when, say, I want to select only Responses whose associated Question IDs are XYZ: when $response : Response( $question : question.ID == XYZ ) // boy howdy does this seem wrong Is the easiest thing to do here to add a second rule that just inserts the questions: when $response : Response then insert($response.getQuestion()) end ...? I would love to stay away from this if I could.

Hi, I know this is repeated again but I tried the solution mentioned in the previous posts and it doesn't work. When I created a guided rule in eclipse, I get blank dropdowns when choosing the facts. I added the jar file for the classes as an external reference I also added a .package file to the directory where my rules are located. The package file contains import statements of the classes. I also added the required classes in the same directory. But nothing seems to work. If I import my .brl rule from the guvnor repository I am unable to open it. Gives me an error. I tried reading it in a text editor and shows me the correct xml format. Please help!!!

Phrases like this should go in a drools best practice sections :-) Does something like that exist? When you read the docs, you get the impression that from is the only way to access objects not explicitly inserted into the working memory. Okay, it seems logical that you can also evaluate them with an explicit or implicit (read invisible) eval. But for me, it isn't really clear when to use an eval, usually promoted as less efficient, and when to use the from operator.

Re: [rules-users] Firing a rule if at least its two conditions are satified
I had to do something like this. The way I did it is by prividing a method in my object in working memory that takes multiple Boolean conditions and loops through them and return true if at least N of the conditions were true. So, this funtions will take N and a list of all conditions. Then it returns true or false. So, your eval will look like this: eval(obj.atLeastNTrue(n, conditionA, conditionB, conditionC, etc)) Sent from my iPhone On Jun 3, 2010, at 7:03 AM, skasab2s skasa...@smail.inf.fh-brs.de wrote: Hello, we are using Drools in our company.

[rules-users] Use Drools-Guvnor .pkg
Hi, I’m new to drools, just started evaluating Drools-Guvnor for a project. To take advantage of Java-enums I’m using the current 5.1.0 Milestone 2. I created a decision table (web-guided) in drools-guvnor and deployed the package snapshot, which is downloadable and returns a .pkg-File. This File is in some Binary format (non plaintext). When I try to load that package in code using a KnowledgeAgent it fails on the following code line: knowledgeAgent.applyChangeSet(resource); with an Exception: “java.lang.RuntimeException: Unable to parse ChangeSet … Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog.”. I debugged it, and it seems to try to parse XML content from this binary file.. Can anyone tell me the proper way to load a package from a remote Guvnor installation? Thx! Complete code: KnowledgeAgent knowledgeAgent = KnowledgeAgentFactory.newKnowledgeAgent(testAgent); UrlResource resource = (UrlResource) ResourceFactory.newUrlResource(url); resource.setBasicAuthentication(enabled); resource.setUsername(whatever); resource.setPassword(); knowledgeAgent.applyChangeSet(resource); KnowledgeBase knowledgeBase = knowledgeAgent.getKnowledgeBase(); Stacktrace: java.lang.RuntimeException: Unable to parse ChangeSet at org.drools.agent.impl.KnowledgeAgentImpl.getChangeSet(KnowledgeAgentImpl.java:323) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:130) at com.efgfp.hermes.drools.test.DroolsTest.testDroolsDecisionTable(DroolsTest.java:37) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodHelper.invokeMethod(MethodHelper.java:644) at org.testng.internal.MethodHelper$1.runTestMethod(MethodHelper.java:762) at org.springframework.test.context.testng.AbstractTestNGSpringContextTests.run(AbstractTestNGSpringContextTests.java:140) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodHelper.invokeHookable(MethodHelper.java:770) at org.testng.internal.Invoker.invokeMethod(Invoker.java:539) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:700) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1002) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:137) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:121) at org.testng.TestRunner.runWorkers(TestRunner.java:908) at org.testng.TestRunner.privateRun(TestRunner.java:617) at org.testng.TestRunner.run(TestRunner.java:498) at org.testng.SuiteRunner.runTest(SuiteRunner.java:329) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:324) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:296) at org.testng.SuiteRunner.run(SuiteRunner.java:201) at org.testng.TestNG.createAndRunSuiteRunners(TestNG.java:915) at org.testng.TestNG.runSuitesLocally(TestNG.java:879) at org.testng.TestNG.run(TestNG.java:787) at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:75) at org.testng.RemoteTestNGStarter.main(RemoteTestNGStarter.java:79) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:110) Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:195) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:174) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:388) at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1411) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl$PrologDriver.next(XMLDocumentScannerImpl.java:1038) at
Re: [rules-users] Object Referencing error:
You can't modify bobject, becuase it doesn't exist inside the session. You
just created it a few lines above. Maybe you need an insert() or maybe you
need the bobject reference from the LHS. Something like this:
*rule* prod
*when*
$a :A(Type == Prod , objectB != )
*then*
B bobject = *new* B();
$a.getObjectB().setType( Prod );
$a.getObjectB().setId($a.getNumber().getId());
*update*($a);
* end*
Note that you need to update $a and not B, because A is the inserted Fact in
your session.

Complete code: KnowledgeAgent knowledgeAgent = KnowledgeAgentFactory.newKnowledgeAgent(testAgent); UrlResource resource = (UrlResource) ResourceFactory.newUrlResource(url); resource.setBasicAuthentication(enabled); resource.setUsername(whatever); resource.setPassword(); knowledgeAgent.applyChangeSet(resource); KnowledgeBase knowledgeBase = knowledgeAgent.getKnowledgeBase(); Stacktrace: java.lang.RuntimeException: Unable to parse ChangeSet at org.drools.agent.impl.KnowledgeAgentImpl.getChangeSet(KnowledgeAgentImpl.java:323) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:130) at com.efgfp.hermes.drools.test.DroolsTest.testDroolsDecisionTable(DroolsTest.java:37) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodHelper.invokeMethod(MethodHelper.java:644) at org.testng.internal.MethodHelper$1.runTestMethod(MethodHelper.java:762) at org.springframework.test.context.testng.AbstractTestNGSpringContextTests.run(AbstractTestNGSpringContextTests.java:140) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodHelper.invokeHookable(MethodHelper.java:770) at org.testng.internal.Invoker.invokeMethod(Invoker.java:539) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:700) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1002) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:137) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:121) at org.testng.TestRunner.runWorkers(TestRunner.java:908) at org.testng.TestRunner.privateRun(TestRunner.java:617) at org.testng.TestRunner.run(TestRunner.java:498) at org.testng.SuiteRunner.runTest(SuiteRunner.java:329) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:324) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:296) at org.testng.SuiteRunner.run(SuiteRunner.java:201) at org.testng.TestNG.createAndRunSuiteRunners(TestNG.java:915) at org.testng.TestNG.runSuitesLocally(TestNG.java:879) at org.testng.TestNG.run(TestNG.java:787) at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:75) at org.testng.RemoteTestNGStarter.main(RemoteTestNGStarter.java:79) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:110) Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog. at
