[rules-users] Drools 5.1 - exception when trying to use incremental KB updates.
Just moved to Drools 5.1, using a Guvnor package as the base for a Knowledge Base with incremental updating enabled. Our resource is a Guvnor PKG. We encounter the following error when a snapshot is made: [2010:08:224 16:08:903:debug] KnowledgeAgent: Diffing: [UrlResource path='http://localhost:1337/drools-guvnor/org.drools.guvnor.Guvnor/package/TEST/v0.1'] [2010:08:224 16:08:935:debug] BinaryResourceDiffProducerImpl: Comparing [Rule name=Resource Null-Checker, agendaGroup=MAIN, salience=0, no-loop=false] against [Rule name=Resource Null-Checker, agendaGroup=MAIN, salience=0, no-loop=false] Exception in thread "Thread-30" org.drools.RuntimeDroolsException: java.lang.reflect.InvocationTargetException : [Rule name=Resource Null-Checker, agendaGroup=MAIN, salience=0, no-loop=false] at org.drools.core.util.ReflectiveVisitor.visit(ReflectiveVisitor.java:56) at org.drools.agent.impl.BinaryResourceDiffProducerImpl.diff(BinaryResourceDiffProducerImpl.java:63) at org.drools.agent.impl.KnowledgeAgentImpl.incrementalBuildResources(KnowledgeAgentImpl.java:785) at org.drools.agent.impl.KnowledgeAgentImpl.buildKnowledgeBase(KnowledgeAgentImpl.java:586) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:185) at org.drools.agent.impl.KnowledgeAgentImpl$ChangeSetNotificationDetector.run(KnowledgeAgentImpl.java:1106) at java.lang.Thread.run(Unknown Source) Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.drools.core.util.ReflectiveVisitor.visit(ReflectiveVisitor.java:47) ... 6 more Caused by: java.lang.RuntimeException: this MVELReturnValueExpression must be compiled for equality at org.drools.base.mvel.MVELReturnValueExpression.equals(MVELReturnValueExpression.java:123) at org.drools.rule.ReturnValueRestriction.equals(ReturnValueRestriction.java:306) at org.drools.rule.ReturnValueConstraint.equals(ReturnValueConstraint.java:121) at java.util.Arrays.equals(Unknown Source) at org.drools.rule.OrConstraint.equals(OrConstraint.java:132) at java.util.AbstractList.equals(Unknown Source) at org.drools.rule.Pattern.equals(Pattern.java:317) at org.drools.rule.GroupElement.equals(GroupElement.java:273) at org.drools.agent.impl.BinaryResourceDiffProducerImpl.compareRules(BinaryResourceDiffProducerImpl.java:258) at org.drools.agent.impl.BinaryResourceDiffProducerImpl.visitRule(BinaryResourceDiffProducerImpl.java:117) ... 11 more The rule in question is quite straight-forward, works on the initial load up and worked in 5.0.1 fine.

Re: [rules-users] How to do validation of facts in a Stateful Session?
Apologies, where I use (Java) I do indeed mean the Java code between calls to fireAllRules(). I'm not entirely sure about how you meant to do it in rules, but how do you then report back to the user that there is a problem? The Java code that calls fireAllRules() has to be able to get errors and then pass them back to the webpage (yay for a project structure which requires me to communicate with the front end by generating XML JSP pages as replies to URL requests from the PHP code which runs the website...)

[rules-users] How to do validation of facts in a Stateful Session?
Hi there, My project uses Drools to (among other things) validate new facts/updates to old facts, according to a set of rules. (For example, we might have a rule that says "No two people can be named the same thing".) Our method of validation and error reporting was originally chosen for a stateless session (before we had the requirement of doing checks like the above), and I feel I've had to hack it a bit much to get it working with stateful sessions. The current methodology is: 1. (Website) The user inserts/updates a fact. 2. (Java) If the fact is new, an object is created for it. If it is an update, the pre-existing object is fetched from the object repository (the interface to the database) and a backup copy of the object is taken. 3. (Java) This fact is either inserted into the KnowledgeBase (KB) or a pre-existing fact in the KB is updated depending. 4. (Rules) If the new/updated object fails a validation rule, it will be retracted and a ValidationError object will be inserted into the KB. 5. (Java) The code then searches for ValidationError objects that match the just inserted/updated object. If it finds any it records them and then retracts them from the KB. 6. (Java) If there are no errors, then that's it - a success report is generated and passed back to the website. 7. (Java) If there were errors, then if the user was updating a fact the backup of it (before the changes) is inserted back into the KB. The website is then passed a failure report. It just feels very hacky to do so much manual insertion/retracting from the Java side of the code. So, is there a 'correct' way to do stateful validation? And does our current way even work, or are there hidden problems that we've not spotted?

[rules-users] Incorrect allowable comparison when using Guvnor GUI Rules - known bug?
Hi there. I was just wondering if the following was a known bug or not (and if it was fixed in Guvnor 5.1 - I am using 5.0): I have two classes, Foo.java and Bar.java. Bar has a property in it, an integer (also tried doubles, not tried anything else) called barInt. Foo also has a property, an instance of Bar called fooBar. Creating a GUI rule in Guvnor, I begin with the 'when' block. I add a check for a Foo. In this Foo, I add a check upon its fooBar parameter. Now, I want to match on the fooBar's barInt property being less than a hundred. So, I click on fooBar, and choose the 'barInt' subfield. It appears, *BUT* there is no option for "is greater than" or "is less than", only "is equals to" and "is not equals to"! I have tried manually creating such a rule, and using "<" or ">" is allowed there, so it is a bug - or at least a missing feature with the GUI. I have an entire report written up, with attatched files and screenshots and everything, but I just wanted to check: A. If this is a known bug. B. If it is fixed in Guvnor 5.1. C. Where to submit bug reports for Guvnor.

[rules-users] Cannot work out how to get created fact to retract on change of 'when' conditions - help!
Hey, We have the following situation: Fact1 and Fact2 both have a 'score' property. They also both have a 'month' property. When a Fact1 and a Fact2 have the same month (at most there will only be one such pairing for each month), a Fact3 is created with a score made from adding the two base Facts scores: rule "ExampleRule" dialect "mvel" when Fact1( fact1Month : month, fact1Score : score > 0) Fact2( month == fact1Month, fact2Score : score > 0) then Fact3 fact3 = new Fact3(); fact3.setScore( fact1Score + fact2Score); insertLogical(fact3); end Our problem is that if fact1Score or fact2Score is now changed, a new Fact3 with a new score is created, *but* the old Fact3 is of course not removed - the conditions in its when still hold true as well (the new score is still above 0). Can anyone think of a way to make sure that if either fact1Score or fact2Score is changed, then the old fact3 is removed from memory? The only way we could at all think to do this is to add a timestamp to fact3, and to have another rule that retracts old fact3s if there is one with a newer timestamp and the same month... but it seems horribly messy.

Re: [rules-users] Updating to 5.1 - what jars do I need to replace?
Apologies Jervis for taking so long to get back to you - and the list. Unfortunately I've been unable to get time to get 5.1 installed on my machine again, since we're in quite a rush here to get the project finished. When I have a bit of free time I will reinstall 5.1 Guvnor and try and re-create the bug. Sorry I am unable to help right atm.

[rules-users] How to compare java.sql.Dates in a Drools 'when'
Hi there, Sorry for so many questions today. How would one compare dates in a Drools when/then rule? I have an object, Tool, that has a last used field which is a java.sql.Date (yes, this is a fairly bad type for it to be. Long story.). I want to write a rule to check if there is a Tool that has this date set in the future. Now, to get the current date/time (in Java!) you would do: java.util.Date today = new java.util.Date(); java.sql.Date sqlToday = new java.sql.Date(today.getTime()); But how do I do something like this in a Drools rule?! (Where I want to compare last used to sqlToday).

Re: [rules-users] How do I totally clear out an installation of Guvnor (Tomcat 6.0)
Thanks Esteban and Jervis, that worked. Just in case it's important, the repository file and directory were actually in the $TOMCAT_HOME folder, not under bin.

I have the following changeset: I just updated to the RC of Guvnor, and my PKG address now demands a username and password when I try and access it.

[rules-users] How do I totally clear out an installation of Guvnor (Tomcat 6.0)
Hi there, I'm migrating to Guvnor RC atm, and was wanting to completely clear out my Guvnor Packages files before I did so - I wanted everything gone. I thought that all information was stored in the Guvnor folder created in Tomcat/webapps, so I deleted that, restarted the server and dragged in the new Guvnor RC WAR file. This built itself fine and is up and running on the server - but my packages are still there! Where abouts are these kept in Apache Tomcat? I can't just delete them from within Guvnor because despite me being able to delete most of the files/packages/etc, there are three categories that claim to be 'still in use' and won't let me delete them... even though there are *no* other files left! Any help is much appreciated.

Re: [rules-users] Automatic updating of Guvnor Rules appears to be not working.
Unfortunately that might be quite tricky, although I can try if
necessary. I do think that perhaps the problem lies in the way I
handle the auto-updating, I think I'm doing it wrong. Originally I
just created the knowledge base and knowledge agent like so, and
started the ResourceChange Notifier and Scanner services:
//construct a knowledgebase that uses Equality mode assert behaviour
so that it can match beans properly
KnowledgeBaseConfiguration knowledgeBaseConfig =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
knowledgeBaseConfig.setProperty("drools.assertBehaviour", "equality");
knowledgeBase = KnowledgeBaseFactory.newKnowledgeBase(knowledgeBaseConfig);
//create a new knowledgeAgent to track changes
knowledgeAgent = KnowledgeAgentFactory.newKnowledgeAgent(
"knowledgeAgent", knowledgeBase );
knowledgeAgent.applyChangeSet( ResourceFactory.newClassPathResource(
"changeSet.xml" ) );
knowledgeBase = knowledgeAgent.getKnowledgeBase();
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
This seemed to claim to update the knowledge base, but nothing changed
as I mentioned before. At the moment, I'm trying rebuilding the
knowledgebase when I detect a change, but this involves re-inserting
the entire database which could be big eventuallly... And it doesn't
even work entirely correctly either XD.
What are the correct steps to take to keep a knowledgeBase
auto-updating, and do you have to re-create it each time?
Thanks,
Stephen

[rules-users] Automatic updating of Guvnor Rules appears to be not working.
Hi there. I'm trying to get automatic update of rules working in my
project, and seem to
have run into a problem. As far as I can tell, automatic polling and
updating is turned
on, and claims to update the knowledgebase, but changes to the rules
don't seem to have
any effect. A simple example - if I add the rule:
rule "TestRule"
dialect "mvel"
when
then
System.out.println("Hello, world!");
end
And start my application, I get:
Firing all rules...
Hello, world!
All rules fired.
As expected. If I then change the rule as follows:
rule "TestRule"
dialect "mvel"
when
then
System.out.println("I have changed!");
end
I get this output (timestamps trimmed for readability):
ResourceChangeScanner attempt to scan 1 resources
ResourceChangeScanner modified resource=[UrlResource
path='http://localhost:1337/drools-guvnor/org.drools.guvnor.Guvnor/package/ERMIE/v0.1']
:

ResourceChangeNotification received ChangeSet notification
ResourceChangeScanner thread is waiting for 60
ResourceChangeNotification processing ChangeSet
ResourceChangeNotification ChangeSet modified resource=[UrlResource
path='http://localhost:1337/drools-guvnor/org.drools.guvnor.Guvnor/package/ERMIE/v0.1']
for listener=org.drools.agent.impl.knowledgeagenti...@e2d0b2
KnowledgeAgent received ChangeSet changed notification
ResourceChangeNotification thread is waiting for queue update
KnowledgAgent applying ChangeSet

KnowledgeAgent adding KnowledgeDefinitionsPackage ERMIE
KnowledgeAgent new KnowledgeBase now built and in use
So, this makes it seem like everything has worked. However, if I
insert a new fact and
fire all rules...
Inserting new fact...
Hello, World!
So, it hasn't worked. What might I have done wrong?
