RE: [rules-users] Problem using KnowledgeAgent

The only thing of interest in the server's log is: 2009-02-20 08:48:31,840 INFO [STDOUT] DEBUG 20-02 08:48:31,840 (SelectorManager.java:<init>:27) Loading selectors 2009-02-20 08:48:31,918 INFO [STDOUT] DEBUG 20-02 08:48:31,918 (ContentManager.java:<init>:45) Loading content properties Though I see no Errors when I clean the estimator project in eclipse, I see the following in the log: !ENTRY org.drools.eclipse 4 120 2009-02-20 08:22:40.109 !MESSAGE Internal error in Drools Plugin: !STACK 0 java.lang.IllegalArgumentException: Could not parse process L/estimator/src/main/rules/TestFlow.rf at org.drools.eclipse.DroolsEclipsePlugin.parseProcess(Unknown Source) ... Don't know where that L comes from as the file is at /estimator/src/main/rules/TestFlow.rf I put the source of the estimator package into a file in eclipse and tried to build it with KnowledgeBuilder, but have the same problem. It just hangs at: kbuilder.add(ResourceFactory.newClassPathResource("estimator.txt", Test.class), ResourceType.DRL); I've attached the estimator.txt file (renamed to txt so the eclipse build wouldn't process it). I could try diving into the drools code to see where it's deadlocking, but my time is very limited today. Let me know and I can find some time this weekend.

I followed your links to get the latest of the greatest. Happy to see all those blue circles in the build history. I downloaded: drools-5.0.0.SNAPSHOT-eclipse-all.zip drools-5.0.0.SNAPSHOT-guvnor.zip Then I updated eclipse with the contents of ...eclips-all.zip, Started eclipse and created a new runtime (which I put in my jboss/server/default/lib folder and verified that the ones I had installed there before were changed). I replaced the M5 version of guvnor with the new one, and restarted everything. That should be all I need to do, right? Been at this for a while, so I may be having a mental lapse. Anyways, several projects that I could build before the upgrade don't build anymore. The build process hangs in Guvnor, as well as in Eclipse. This is the last output I get in the server's log when trying to compile the package I'm using for our test: 21:27:25,132 INFO [STDOUT] DEBUG 19-02 21:27:25,132 (SelectorManager.java:<init>:27) Loading selectors 21:27:25,195 INFO [STDOUT] DEBUG 19-02 21:27:25,195 (ContentManager.java:<init>:45) Loading content properties The last thing I see in Eclipse when I try a complete clean on our primary application is: Building Workspace - Building all...: Invoking "Drools Builder' on '/cbo-ejb'. The status shows 46% complete and just hangs there. I think it's time for a cocktail and a nice long sleep. I'll check in tomorrow before rolling back to M5. can you look in the error logs? I was really hoping to CR1 over the weekend. But we need to be sure these issues are gone. Also if it's in guvnor and eclipse it sounds like a generic problem with drools compiler. Can I ask you to remove the plugin and try and build the rules via the knowledgebuilder yourself, hopefully you'll find the deadlock there yourself and be able ot print a stack trace we can actually use. Along with the offending rules.

The exception occurs when I issue: agent.monitorResourceChangeEvents(true|false) If I comment out that code, I don't get the exception, but I don't get changes either. I tried it with both the Guvnor repository and with a deployed package on the file system. I won't have time to create the test you requested until the weekend. Let me know if you still want it. Dan Mark Proctor wrote: Dan Seaver wrote: I setup a KnowledgeAgent using the example code in the JavaDoc for KnowledgeAgentFactory to access a compiled package in Guvnor. The package runs fine, but changes to the package are not picked up. I believe this is due to the ChangeSet notification thread being interrupted. But why? Hmm that's not good. I have the following unit test: http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-compiler/src/ test/java/org/drools/agent/KnowledgeAgentTest.java Could you provide an update for new tests for detecting url changes? When making the test you might find it easier to look at the previous ruleagent tests: http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-core/src/test /java/org/drools/agent/URLScannerTest.java Mark Also, I'm getting some messages about failing to read schema document. I think it is caused by the xml for the ChangeSet, but I'm using the example from the JavaDocs. We haven't provided an XSD yet, so it'll provide schema validation issues, those can be ignored.
