Dear Drools users, I have been testing with the KnowledgeAgent from version 5.4 and 5.5. It monitors a changeset and is set to incrementally build the knowledgebase. I noticed that it sometimes crashes but never throws out errors. This happens for example when I define a type two times and when I remove a file. Does anyone experience similar behaviour and has an idea of how I could see the errors? I already tried to check the errors by building it myself using a knowledgebuilder before I update the file that the knowledgeAgent monitors but that's quite a dirty solution. Kind Regards, De Rooms Brecht _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Hello David and thanks for responding. I know it supports these event listeners and I use them. In my program, I have two knowledge agents and the first one (preprocessing) will read the file, preprocess a DRL and then write a second modified DRL file in a folder that is monitored by the second one. When I modify the original DRL file *(1.* in prints below*)* monitored by the preprocessing agent, everything works fine and the rule is triggered*(**2.)*. However, when I delete a file *(**3.)*, the knowledgeAgent just blocks after AfterChangeSetAppliedEvent and does not do anything anymore.. If I send new data in the knowledgeAgent it does not react anymore. I would expect to get a stacktrace of what went wrong but I do not get any info besides of the systemeventlistener or knowledgeagentlistener. Is there any way I can get a stacktrace?

Dear Drools users, Apparently it was not caused by the previously mentioned fix. Sometimes I still had a KnowledgeAgent in my server that doesn't respond anymore which seems to be caused by a mistake in the DRL file. I started to investigate the source code of KnowledgeAgentImpl and KnowledgeBaseImpl and recompiled them to add some prints. Finally I tracked it until AbstractRuleBase.addPackages. There is a giant Try-final block and I noticed by adding prints that it stopped somewhere in the middle. When it does fail, my KnowledgeAgent stops working completely. The try-final seemed to be the only place for me where an exception might be ignored so I added a catch clause. As a result, the error report of my drl file was nicely printed and my agent didn't crash: *org.drools.RuntimeDroolsException: Unable to resolve class 'int' for global 'RULES_MATCHED' at org.drools.common.AbstractRuleBase.mergePackage(AbstractRuleBase.java:818) at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:615) at org.drools.reteoo.ReteooRuleBase.addPackages(ReteooRuleBase.java:472) at org.drools.impl.KnowledgeBaseImpl.addKnowledgePackages(KnowledgeBaseImpl.java:153) at org.drools.agent.impl.KnowledgeAgentImpl.addResourcesToKnowledgeBase(KnowledgeAgentImpl.java:1173) at org.drools.agent.impl.KnowledgeAgentImpl.incrementalBuildResources(KnowledgeAgentImpl.java:1058) at org.drools.agent.impl.KnowledgeAgentImpl.buildKnowledgeBase(KnowledgeAgentImpl.java:738) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:259) at org.drools.agent.impl.KnowledgeAgentImpl$ChangeSetNotificationDetector.run(KnowledgeAgentImpl.java:1357) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) * Maybe there is a reason for this missing catch so I am not sure whether I fixed it and broke something else ( eg. maybe I should undo a part of the operations before I continue). Is there anyone who knows this code and who can help me?

It is a bug, the KA can detect compilation errors in resources, but will not capture runtime exceptions.

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-Knowl...
