For those interested, we just got the new rule algorithm to pass 100% of our existing tests. So we'll be merging those changes in tomorrow :) http://blog.athico.com/2013/01/life-beyond-rete-rip-rete-2013.html Mark

Protobuf error

by Michael Anstis

Hi, Drools Workbench has started to get failing tests due to this:- java.lang.NoClassDefFoundError: com/google/protobuf/Message at org.drools.compiler.kie.builder.impl.KieServicesImpl.newKieBuilder(KieServicesImpl.java:87) at org.kie.workbench.common.services.builder.Builder.build(Builder.java:116) at org.kie.workbench.common.services.builder.BuildServiceImplTest.testBuilderSimpleKProject(BuildServiceImplTest.java:69) 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.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.runners.ParentRunner.runLeaf(ParentRunner.java:271) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:70) at org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:50) at org.junit.runners.ParentRunner$3.run(ParentRunner.java:238) at org.junit.runners.ParentRunner$1.schedule(ParentRunner.java:63) at org.junit.runners.ParentRunner.runChildren(ParentRunner.java:236) at org.junit.runners.ParentRunner.access$000(ParentRunner.java:53) at org.junit.runners.ParentRunner$2.evaluate(ParentRunner.java:229) at org.junit.runners.ParentRunner.run(ParentRunner.java:309) at org.apache.maven.surefire.junit4.JUnit4Provider.execute(JUnit4Provider.java:252) at org.apache.maven.surefire.junit4.JUnit4Provider.executeTestSet(JUnit4Provider.java:141) at org.apache.maven.surefire.junit4.JUnit4Provider.invoke(JUnit4Provider.java:112) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.apache.maven.surefire.util.ReflectionUtils.invokeMethodWithArray(ReflectionUtils.java:189) at org.apache.maven.surefire.booter.ProviderFactory$ProviderProxy.invoke(ProviderFactory.java:165) at org.apache.maven.surefire.booter.ProviderFactory.invokeProvider(ProviderFactory.java:85) at org.apache.maven.surefire.booter.ForkedBooter.runSuitesInProcess(ForkedBooter.java:115) at org.apache.maven.surefire.booter.ForkedBooter.main(ForkedBooter.java:75) Has something changed upstream? Do we need additional dependencies? I remember seeing on IRC yesterday that marshalling had broken(?) is this related. With kind regards, Mike

Beta3 sanity check

by Michael Anstis

Hello, I've tested Beta3 kie-drools-wb and kie-wb on AS7. These are my findings:- *kie-drools-wb *1) Generally looked OK to me 2) The JGIT daemon is not terminated when the webapp is removed/disabled (I've emailed Alexandre). *kie-wb * 1) dom4j.jar needs deleting from WEB-INF/lib 2) I did not test any jBPM related screens (Task List, Designer etc) 3) The JGIT daemon is not terminated when the webapp is removed/disabled (I've emailed Alexandre). 4 I encountered the following error:- 09:46:19,545 ERROR [stderr] (http--127.0.0.1-8080-2) java.lang.NullPointerException 09:46:19,547 ERROR [stderr] (http--127.0.0.1-8080-2) at org.jbpm.kie.services.impl.KModuleDeploymentService.deploy(KModuleDeploymentService.java:68) 09:46:19,548 ERROR [stderr] (http--127.0.0.1-8080-2) at org.jbpm.kie.services.impl.KModuleDeploymentService$Proxy$_$$_WeldClientProxy.deploy(KModuleDeploymentService$Proxy$_$$_WeldClientProxy.java) 09:46:19,548 ERROR [stderr] (http--127.0.0.1-8080-2) at org.jbpm.console.ng.bd.backend.server.DeploymentManagerEntryPointImpl.deploy(DeploymentManagerEntryPointImpl.java:77) 09:46:19,549 ERROR [stderr] (http--127.0.0.1-8080-2) at org.jbpm.console.ng.bd.backend.server.DeploymentManagerEntryPointImpl.autoDeploy(DeploymentManagerEntryPointImpl.java:165) 09:46:19,568 ERROR [stderr] (http--127.0.0.1-8080-2) at org.jbpm.console.ng.bd.backend.server.DeploymentManagerEntryPointImpl$Proxy$_$$_WeldClientProxy.autoDeploy(DeploymentManagerEntryPointImpl$Proxy$_$$_WeldClientProxy.java) This came about by creating a "New Project" and "Build & Deploying" it. The project did not contain any jBMP assets (only a dependency on a JAR uploaded to Guvnor's M2 Repository and a simple rule). It didn't throw any errors to the UI so I don't think it's serious. Otherwise both were OK. I've asked Toni and Jervis to perform a sanity check too. With kind regards, Mike

New rules are not reflecting at runtime without Binary package build in Guvnor UI

by Antin Brucelee -X (abrucele - INFOSYS TECHNOLOGIES LIMITED＠Cisco)

Hi, I have a requirement of executing all the rules under a specific package. The new rules getting added in Guvnor API and Standalone editior are not getting reflected until I build the Binary package again using Guvnor UI. I want to allow users to create new rules and want them to be active immediately without coming to Guvnor to build the binary again. I tried making a GET request to "http://... /rest/packages/SupplyChain/binary" to build the binary again, but the new rule is not reflected. I also tried the following configuration also. ResourceChangeScannerConfiguration sconf = ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration(); sconf.setProperty("drools.resource.scanner.interval", "2"); ResourceFactory.getResourceChangeScannerService().configure(sconf); KnowledgeAgentConfiguration kaconf = KnowledgeAgentFactory.newKnowledgeAgentConfiguration(); kaconf.setProperty( "drools.agent.scanDirectories","true" ); kaconf.setProperty("drools.agent.scanResources", "true"); kaconf.setProperty("drools.agent.newInstance", "false"); Please let me know if there is any other way of building the package with all the latest updates (including new assets) using REST API ? Thanks Bruce Thanks Antin

Guvnor Standalone editor - How to copy an existing asset (Decision table)

by Antin Brucelee -X (abrucele - INFOSYS TECHNOLOGIES LIMITED＠Cisco)

Hi, I am using Guvnor Standalone editor in my website to display and allow editing the rules. I have a requirement to copy existing rules and then allow users to make any changes on top of it. I see the 'copy' feature is available Guvnor UI. Is there a way to achieve this feature by using REST API and Standalone editor in my website ? Thanks Bruce
