Re: [rules-users] KnowledgeAgent Changeset problems
There is the use case where the changeset.xml is read from Guvnor - that is what we are trying to do, and we don't have the option to specify where the schema lives. Perhaps schema validation should be false by default instead of true.

Re: [rules-users] KnowledgeAgent custom class loader not working for PKG resources
In debug, KnowledgeAgentImpl.createPackageFromResource(), the last line to run is DroolsStreamUtils.streamIn(is), then an excecption is caught: this.listener.exception( new RuntimeException( KnowledgeAgent exception while trying to deserialize KnowledgeDefinitionsPackage , ex)); The exception here says java.lang.ClassNotFoundException: org.ihc.hwcir.drools.facts.Patient, which is my Fact model. It doesn't seem to get surfaced anywhere. As my sample illustrates, if I switch to DRL changeset, or put Patient.jar on classpath all works fine.

RE: [rules-users] Drools Community Clinic Feb 4th 5PM GMT
Like many folks in the user-list, I too am recently evaluating Drools for my organization. So while I have a basic understanding of the many great features of Drools, how to integrate it into a high volume, highly reliable enterprise system is still somewhat of a mystery. One specific thing I have been wondering about is the use of StatefulKnowledgeSessions. It seems in the last few years the JEE world has favored simplicity and stateless systems to a large degree. If my system has to be highly reliable, meaning I must guarantee (99.x%) that all data gets processed correctly, then how does one handle a StatefulKnowledgeSession that crashes? I have seen discussion about serialization of WorkingMemory, but that has to be costly with a large number of facts. Is hardware mirroring the only real solution? I'd be interested in learning more about how Drools is or should be used in this type of environment.

So the idea here isn't of a 60 minute presentation, but really more of a 60 minute interactive QA where we will use the desktop to assist in some explanations talking through code or examples. What do people think? Ideally we would have a set of pre-determined questions, with some adhoc ones on the day too. Feel free to start listing your Qs here. I want to avoid What's WorkingMemory type questions, but other than that, anything is game. Also if anyone has anything cool they would like to discuss about how they have used Drools, or just general interesting AI ideas, then that's fine too - happy for this just to turn into a fun geek chat too.

[rules-users] Guvnor Issues
Hi, I've been working with the Model feature in Guvnor 5.M4 and have some questions: 1. Is there a way to delete a fact type once created? 2. When I declare a field as a Date it gets included as a java.lang.Date and the fact will not validate. 3. If I have created two facts, the one created first cannot reference the second one as the type of a field. The second on can reference the first. It would be nice to support this forward -referencing feature. I'd be happy to enter any of these in Jira if they are not already present (couldn't find them).

[rules-users] Eclipse Agenda View not working in 5.0.0.M4
Hi, I am trying to debug a rule using Eclipse 3.4, Drools 5.0.0.M4, and all I ever see in the Agenda View is: MAIN[nofocus]=BinaryHeapQueueAgendaGroup (id=2259) I can step into the rule successfully and WorkingMemory View works too. Any suggestions? Thanks, Herman Post ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
