Re: [rules-users] IllegalStateException happens when ResourceChangeScanner working on Version 5.3.0.CR1

Hi Guys, I want to upgrade drools from 5.1.1 to 5.3.0 CR1, but i found ResourceChangeScanner could't work. In version 5.1.1, i wrote this code to get a KnowledgeAgent KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("ReleaseAgent"); kagent.addEventListener(new ReloadingRuleEventListener(this)); kagent.applyChangeSet(ResourceFactory.newClassPathResource("changeset-url.xml")); changeset-url.xml content is like: <change-set xmlns='http://drools.org/drools-5.0/change-set' xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/... <add> <resource source='http://hostname:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/PackageName1/snapshot_release' type='PKG' basicAuthentication="enabled" username="user1" password="123456" /> <resource source='http://hostname:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/PackageName2/snapshot_release' type='PKG' basicAuthentication="enabled" username="user1" password="123456" /> <resource source='http://hostname:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/PackageName3/snapshot_release' type='PKG' basicAuthentication="enabled" username="user1" password="123456" /> </add> </change-set> then wrote this code to scan if there is a new version snapshot on guvnor ResourceChangeScannerConfiguration sconf = ResourceFactory .getResourceChangeScannerService() .newResourceChangeScannerConfiguration(); sconf.setProperty("drools.resource.scanner.interval","60"); ResourceFactory.getResourceChangeScannerService().configure(sconf); ResourceFactory.getResourceChangeScannerService().start(); ResourceFactory.getResourceChangeNotifierService().start(); It works very well, each time when ResourceChangeScanner finding there is new snapshot, it can reload the rules from guvnor properly. But when i updated to 5.3.0 CR1, ran this code, error happens: Exception in thread "Thread-2" java.lang.IllegalStateException: reader does have a modified date at org.drools.io.impl.ReaderResource.getLastModified(ReaderResource.java :64) at org.drools.io.impl.ResourceChangeScannerImpl.scan(ResourceChangeScann erImpl.java:169) at org.drools.io.impl.ResourceChangeScannerImpl$ProcessChangeSet.run(Res ourceChangeScannerImpl.java:326) at java.lang.Thread.run(Thread.java:619) It seems in new version, UrlResource was parsed to ReaderResource(i rememer in 5.1.1, each resource in changeset-url.xml was parsed to UrlResource). Can you give a help? Thanks a lot -- View this message in context: http://drools.46999.n3.nabble.com/IllegalStateException-happens-when-Reso...
