[rules-users] Declared Types and Globals in different files with incremental KnowledgeAgent
Dear Drools Users, I am building a network server for drools since the existing drools-server did not meet my requirements. Since I recently found a bug and find the people here very helpful I'll try to explain another issue I encountered in the hope that it improves drools 5.6 and 6.0. I noticed that declared types and globals don't seem to be found when you access them from a rule that was written in a different file. For the declared types I hacked around this issue by preprocessing the files and placing every declared type at the top of each file that needs it. For globals this is of course not possible. An example is shown below. File1 is loaded from the moment the agent starts up, then file2 is loaded. There is a difference when the knowledgeAgent detects the two files at once or one by one. In this case the KnowledgeAgent detects one file and then a few minutes later the other file and compiles them completely separately. The idea is to keep how many rules are matched of a certain type in a global. * FILE1: global_rules_matches.drl -- package ellipsoidfacts // declare global Integer RULES_MATCHED; // initialize global rule initRULESMATCHED salience 999 when then RULES_MATCHED = 0; end* * FILE2: testrule.drl -- package ellipsoidfacts rule Gesture_lefthook when // ... any precedent rules ... then System.out.println(matched gesture: lefthook+ RULES_MATCHED); end* In this particular case, my rule is not matched. I load these rules using a changeset xml, my knowledgeagent is set to incremental (but either doesnt work). The same happens when I declare types in FILE1 and use them in FILE2. When I write the type declaration in both files it works perfectly. Being the same package I assumed that these two scenarios should work. Am I doing something wrong or is the agent not supposed to work like this and should a package be in one file?

Re: [rules-users] Optaplanner rules error
I'm unable to figure it out. At the top of the drl file I have:
package be.comp.permanenties.solver; //permanentiesScoreRules.drl
dialect java
import org.optaplanner.core.api.score.buildin.hardsoft.HardSoftScoreHolder;
import be.comp.permanenties.domain.DayOfWeek;
import be.comp.permanenties.domain.Employee;

import be.comp.permanenties.domain.request.ShiftOnRequest;
import be.comp.permanenties.domain.solver.EmployeeAssignmentTotal;
import be.comp.permanenties.domain.solver.EmployeeWorkSequence;
The EmployeeAssignmentTotal sits in the right package and the top of the
file is:
package be.comp.permanenties.solver;
import java.io.Serializable;
import org.apache.commons.lang.builder.CompareToBuilder;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import be.comp.permanenties.domain.Employee;
public class EmployeeAssignmentTotal implements
ComparableEmployeeAssignmentTotal, Serializable {
For now the project is just a copy of the nurse rostering problem with some
omissions of things I don't think I will need. I am now trying to get
something fairly simple up and running. The program will replace a manual
employee planning tool in Excel. But the planning tool they use now doesn't
look at holidays or days off. The aim of the program is to do everything
automatically and integrate it with the hour registration program. But as
you can see I am only beginning. Deadline is the end of this year.
Kind regards,
Nick

[rules-users] Insert, fire, then retract from consequence
I am wondering if I can insert a fact, fire all activated rules, then retract the fact all in a rules consequence. I have similar behavior using the API that I'd like to be able to do inside a rule, as well. The idea is that once all the rules that cause activations get fired, it gets retracted immediately. This is so that we don't have to have cleanup rules all over the place, and have to ensure that the salience is set correctly. Any ideas? Thanks in advance!

On 20/09/2013, Jonathan Knehr jonathan.kn...@gmail.com wrote: I am wondering if I can insert a fact, fire all activated rules, then retract the fact all in a rules consequence. Certainly. But the fireAllRules() would have to address a session different from the one that's executing the consequence.

The idea is that once all the rules that cause activations get fired, it gets retracted immediately. This is so that we don't have to have cleanup rules all over the place, and have to ensure that the salience is set correctly. Is it a fact? You can retract it from the place where it was inserted, for instance. Well-designed rule sets don't have cleanup rules all over the place. And salience is a last resort, not a first-class way of designing rule sets. Any ideas? Thanks in advance!

Re: [rules-users] No errors thrown from KnowledgeAgent
Let the team correct me if I'm mistaken or imprecise. There is no commercial version, the only thing you can get is a productized version which has been through Q/A for a longer period, usually 6 months. The strategy is to get features out in the community version, get feedback from there and make them part of the product when they're more mature. If you pay for the product, **I think** that you'll actually get support and bug fixes based on a SLA. Otherwise, you'll just have to report them and wait until somebody will have the time to fix them, possibly in a future version. Or provide a fix yourself :) Best Davide -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-No-errors-thrown-from-KnowledgeAgent-tp4025209p4026066.html Sent from the Drools: User forum 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] Declared Types and Globals in different files with incremental KnowledgeAgent
Brecht, thanks for reporting this, but I don't think these are bugs. 1) In order to set the value of a global from a rule's RHS, you have to do somehting like this drools.getKnowledgeRuntime().setGlobal( RULES_MATCHED, newValue ); The reason is that the rule's RHS sees a reference to the original global... a local variable with the same name initialized appropriately. Something like RULES_MATCHED = 0 will only change the local reference, not modify the global. 2) The KnowledgeAgent supports declared types incrementally.. (Esteban and I spent a lot of time to make that work), but you have to set a flag in the KA's configuration: KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); aconf.setProperty( drools.agent.useKBaseClassLoaderForCompiling, true ); The incremental mode (newInstance=false) only ensures that the existing KnowlegeBase is updated, tue useKBaseClassLoaderForCompiling will ALSO make sure that, as the new resources are compiled by a KnowledgeBuilder, this is initialized with the KB's classloader, which has the classes for the declared types. 3) I have proposed a fix for the issue you reported the other day... actually two in one. - 3a ) Runtime exceptions will be catched, - 3b ) you **WILL NOT** be able to use primitive types with globals anymore.. (which would result in a RTE anyway) Hope this help Best Davide On 09/20/2013 02:18 AM, De Rooms Brecht wrote: Dear Drools Users, I am building a network server for drools since the existing drools-server did not meet my requirements.
