[rules-users] RuntimeDroolsException: Unable to load dialect
Hi, I am trying to run Drools on Netbeans. I have added the jars from Drools 4.0.2. However, I encountered an error org.doxa.rules.RulesManager - org.drools.RuntimeDroolsException: Unable to load dialect ' org.drools.rule.builder.dialect.mvel.MVELDialectConfiguration:mvel' I did not use any MVEL dialects in my rules definition. Here is my rule: * rule* Out of Range *when * m : Message( message == checkRange , status == 1 ) Range(myMin : myMin, myMax : myMax, myValue : myValue) Range(myValue myMin || myValue myMax) *then* m.setMessage(); m.setStatus(0); *end * Has anyone attempted using Netbeans with Drools and faced this problem?

[rules-users] jdt core API issue Drools 4.0 and apache-tomcat-5.5.17
Hi All Drools 4.0 is using ecj-latest.jar file for jdt core API. apache-tomcat-5.5.17 is using jasper-compiler-jdt.jar file for jdt core API. The CompilationResult class is one of the class in jdt core API. But the jar files are having different versions of CompilationResult class. So we are unable to incorporate Drools 4.0 application with tomcat. please let me know if you have any solution. regards Marimuthu The information contained in this electronic message and any attachments to this message are intended for the exclusive use of the addressee(s) and may contain proprietary, confidential or privileged information.

Re: [rules-users] activationCancelled() not being executed?
I did some major code-cleaning in the meantime and I feel a bit more comfortable now... Unfortunately this still didn't help me with my two problems: a) I still have the problem that my activations don't get canceled. b) I don't think that I'll be able to distill the code in order to get a self-contained project out of it. So instead I had a closer look at the Manners example and I found only two obvious differences from my code: 1. Manners uses a StatefulSession object, whereas I used a WorkingMemory instance. I changed my code to use a StatefulSession as well, but the strange behavior didn't disappear. 2. Manners uses the standard ClassLoader while I'm using an URLClassLoader in order to access my rule files (I plan to deploy my application as a single executable .jar file (created with Fat Jar eclipse plugin), but I want to have my rule files in a separate folder). Changing this didn't help either. So this basically means, that there is another difference that I've missed so far. What I HAVE seen is, that the fact IDs of my rules change (I think this is a good thing): If I insert a fact with a temperature value of (e.g.) -15 °C, a temperature-out-of-range rule gets activates (not fired). In my little table an activation is added caused by the fact with the fact ID 21:34. Now I change the temperature of this fact back to something in range (e.g.) 20°C. Instead of the activation being canceled and therefore disappearing from my table, it just stays there. Now I change the temperature back to something that is out of range: -30 °C. A NEW activation is inserted into my table with a fact ID of 21:38. At the same time, the fact ID of the first (still persistent) activation changes to 21:38 as well! I hope that this means that drools realizes that the fact value of the first value has changed. But if this is true, then drools also noticed that the value changed before, without cancelling the activation. To my knowledge this also proves that my implementation of the fact beans hashCode() and equals() methods is working correctly. There has to be an error in my reasoning.

Re: [rules-users] activationCancelled() not being executed?
Hi again! Finally I realized that it would be best to do what I was asked for: supply some self-contained test code. Although it was a rather painful process, it was worth it, as the strange behavior is still present. I'm far from saying that this is a bug. On the contrary, I'm quit sure it's just a very stupid thing in my code. But at least it should be easier for someone else to have a look now... Just download the 3 following files and copy them into the same directory. As I was to lazy to include something more clever, I hardcoded this path, so that you'll need to modify the line String absoluteFilePath = C:/Dokumente und Einstellungen/Henss/workspace/DeploymentTest/; to point to your folder. If you use Eclipse and the Drools plugin, you should also be able to browse this directory for the created log files (of course after running the small app at least once) using the Audit View. I hope this helps to narrow it down a bit.

Really looking forward to the patch :) Ok, so whose writing the patch? Can we have a spec of whats exactly needed?! I've been wiating for agenda Groups in Decision tables for a long time. I've created my own ways of forcing sequence in decision tables (using extended attributes in the condition itself); but theres room for elegance by using AGENDA Groups. All other attribs can be coded in conditions also; so its importat to draw a line and say whatever falls on this side of the line is a legitimate attribute or else the user may use a condition as a substitute. Personally I care about AGENDA Groups the max; lack of it retards decision tables considerably.

Is this simply putting a salience in order from top to down for rules or someting else how do I use this Sequential Execution Flow (If it is not what I think it is), how is it faster and consume lesser memory? The sequential mode and ts impl is detailed in the manual. This is different from the sequential setting on decision tables, which just uses an increasing salience number, nothing else.

Re: [rules-users] ClassCastException when redeploying to jboss
Jeffery,
We fixed that bug for 4.0.2. Can you make sure you are using version
4.0.2?
http://jira.jboss.com/jira/browse/JBRULES-1239
Thanks,
Edson
2007/10/15, Jeffery Shutt [EMAIL PROTECTED]:
We have a server application that runs on jboss and we are trying to use
drools as part of it. I have one object that I insert into WorkingMemory and
when I first start up jboss and run through my rules everything works fine.
If I re-deploy my server to jboss (without restarting it) and try to fire my
rules again I get a ClassCastException on {MyObject}ShadowProxy. If I stop
and restart jboss it works fine again. It seems like something ({MyObject}
specifically) is not being re-loaded when the application is re-deployed.
Any help pointing me in the right direction would be nice.
