Re: [rules-users] Use Drools-Guvnor .pkg

Hi, I’m new to drools, just started evaluating Drools-Guvnor for a project. To take advantage of Java-enums I’m using the current 5.1.0 Milestone 2. I created a decision table (web-guided) in drools-guvnor and deployed the package snapshot, which is downloadable and returns a .pkg-File. This File is in some Binary format (non plaintext). When I try to load that package in code using a KnowledgeAgent it fails on the following code line: knowledgeAgent.applyChangeSet(resource); with an Exception: “java.lang.RuntimeException: Unable to parse ChangeSet … Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog.”. I debugged it, and it seems to try to parse XML content from this binary file.. Can anyone tell me the proper way to load a package from a remote Guvnor installation? Thx! Complete code: KnowledgeAgent knowledgeAgent = KnowledgeAgentFactory.newKnowledgeAgent("testAgent"); UrlResource resource = (UrlResource) ResourceFactory.newUrlResource(url); resource.setBasicAuthentication("enabled"); resource.setUsername("whatever"); resource.setPassword(""); knowledgeAgent.applyChangeSet(resource); KnowledgeBase knowledgeBase = knowledgeAgent.getKnowledgeBase(); Stacktrace: java.lang.RuntimeException: Unable to parse ChangeSet at org.drools.agent.impl.KnowledgeAgentImpl.getChangeSet(KnowledgeAgentImpl.java:323) at org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:130) at com.efgfp.hermes.drools.test.DroolsTest.testDroolsDecisionTable(DroolsTest.java:37) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodHelper.invokeMethod(MethodHelper.java:644) at org.testng.internal.MethodHelper$1.runTestMethod(MethodHelper.java:762) at org.springframework.test.context.testng.AbstractTestNGSpringContextTests.run(AbstractTestNGSpringContextTests.java:140) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.testng.internal.MethodHelper.invokeHookable(MethodHelper.java:770) at org.testng.internal.Invoker.invokeMethod(Invoker.java:539) at org.testng.internal.Invoker.invokeTestMethod(Invoker.java:700) at org.testng.internal.Invoker.invokeTestMethods(Invoker.java:1002) at org.testng.internal.TestMethodWorker.invokeTestMethods(TestMethodWorker.java:137) at org.testng.internal.TestMethodWorker.run(TestMethodWorker.java:121) at org.testng.TestRunner.runWorkers(TestRunner.java:908) at org.testng.TestRunner.privateRun(TestRunner.java:617) at org.testng.TestRunner.run(TestRunner.java:498) at org.testng.SuiteRunner.runTest(SuiteRunner.java:329) at org.testng.SuiteRunner.runSequentially(SuiteRunner.java:324) at org.testng.SuiteRunner.privateRun(SuiteRunner.java:296) at org.testng.SuiteRunner.run(SuiteRunner.java:201) at org.testng.TestNG.createAndRunSuiteRunners(TestNG.java:915) at org.testng.TestNG.runSuitesLocally(TestNG.java:879) at org.testng.TestNG.run(TestNG.java:787) at org.testng.remote.RemoteTestNG.run(RemoteTestNG.java:75) at org.testng.RemoteTestNGStarter.main(RemoteTestNGStarter.java:79) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:110) Caused by: org.xml.sax.SAXParseException: Content is not allowed in prolog. at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.createSAXParseException(ErrorHandlerWrapper.java:195) at com.sun.org.apache.xerces.internal.util.ErrorHandlerWrapper.fatalError(ErrorHandlerWrapper.java:174) at com.sun.org.apache.xerces.internal.impl.XMLErrorReporter.reportError(XMLErrorReporter.java:388) at com.sun.org.apache.xerces.internal.impl.XMLScanner.reportFatalError(XMLScanner.java:1411) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl$PrologDriver.next(XMLDocumentScannerImpl.java:1038) at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:648) at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:140) at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:510) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:807) at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:737) at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:107) at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1205) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:522) at javax.xml.parsers.SAXParser.parse(SAXParser.java:395) at org.drools.xml.ExtensibleXmlParser.read(ExtensibleXmlParser.java:295) at org.drools.xml.ExtensibleXmlParser.read(ExtensibleXmlParser.java:174) at org.drools.xml.XmlChangeSetReader.read(XmlChangeSetReader.java:49) at org.drools.agent.impl.KnowledgeAgentImpl.getChangeSet(KnowledgeAgentImpl.java:320) ... 36 more -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Use-Drools-Guvnor-pkg...
