Ok. I put that in but I'm having trouble getting it to recognize the uri I'm passing in. I'm passing in "file:///c:/svn/code/sleuth/src/net/intellidata/sleuth/description/rules/" and I'm getting the following exception: RuleAgent(default) INFO (Mon Apr 07 13:14:40 MDT 2008): Configuring with newInstance=true, secondsToRefresh=300 RuleAgent(default) INFO (Mon Apr 07 13:14:40 MDT 2008): Configuring package provider : URLScanner monitoring URLs: file:/c:/svn/code/sleuth/src/net/intellidata/sleuth/description/rules/ with local cache dir of . java.lang.ClassCastException: sun.net.www.protocol.file.FileURLConnection at org.drools.agent.HttpClientImpl.checkLastUpdated(HttpClientImpl.java:26) at org.drools.agent.URLScanner.hasChanged(URLScanner.java:141) at org.drools.agent.URLScanner.getChangeSet(URLScanner.java:108) at org.drools.agent.URLScanner.loadPackageChanges(URLScanner.java:88) at org.drools.agent.RuleAgent.checkForChanges(RuleAgent.java:330) at org.drools.agent.RuleAgent.refreshRuleBase(RuleAgent.java:298) at org.drools.agent.RuleAgent.configure(RuleAgent.java:284) at org.drools.agent.RuleAgent.init(RuleAgent.java:208) at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:176) at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:148) at net.intellidata.sleuth.description.rules.DescriptionRuleLoader.loadRules(Des criptionRuleLoader.java:48) at net.intellidata.sleuth.description.rules.DescriptionRuleLoaderTest.testDescr iptionRuleLoader(DescriptionRuleLoaderTest.java:32) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at junit.framework.TestCase.runTest(TestCase.java:154) at junit.framework.TestCase.runBare(TestCase.java:127) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:118) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3T estReference.java:130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:3 8) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRu nner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRu nner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner. java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner .java:196) The goal here is to monitor the directory above for any changes to the files or additional files that show up.

The Javadoc on this class gives more info. Code sample (assuming that you have the BRMS setup as per the doc). You'll need to change to whatever settings are appropriate for your BRMS. Properties prop = new Properties(); prop.setProperty("url",uri); prop.setProperty("newInstance", "true"); prop.setProperty("localCacheDir", "."); prop.setProperty("poll", "300"); // poll every 300 seconds for hot deployment. //Get a new RuleBase using these properties RuleAgent agent = RuleAgent.newRuleAgent(prop); RuleBase rb = agent.getRuleBase(); Then use the RuleBase as normal Paul Brian Trezise wrote: In the What's New? Section of the Drools 4.0 documentation there is a reference in 1.1.2 to a "Rules Engine Agent for hot deployment and BRMS integration". This would be ideal for the application I am currently developing. However, this is the only mention of this agent anywhere in the documentation. Does anybody know anything about this, how to use it, any documentation about it?

The object is still in its initial state, the rules did not manipulate the object in any way. I am using the RuleAgent class to monitor a directory full of .drl files and load them into the rulebase. This is my load rules code: public static RuleBase loadRules() throws Exception { Properties prop = new Properties(); prop.setProperty(RuleAgent.DIRECTORY, "c:/intellidata-home/sleuth/drlFiles"); prop.setProperty(RuleAgent.POLL_INTERVAL, "300"); // poll every 300 seconds for hot deployment. // Get a new RuleBase using these properties RuleAgent agent = RuleAgent.newRuleAgent(prop); RuleBase ruleBase = agent.getRuleBase(); Thread.sleep(5000); return ruleBase; } If I load the rules manually, without using the RuleAgent, then the rules modify the fact object in exactly the way they are supposed to. Essentially it appears to me that the rules are not firing. I've looked at the FileScanner and RuleAgent source code and have not been able to determine the problem, it appears that this should work. Can anybody look at this and tell me if this is a bug or if I'm doing something wrong?
