Hi all, I've tried drools 5.2 final version with much excitement but the default create new drools project is already giving problems: Issue 1. Exceptions when running default created .rf and .bpmn files. When I ran ProcessTest.java with .rf file, I get: java.lang.NullPointerException at org.drools.compiler.PackageBuilder.addProcessFromXml(PackageBuilder.java:516) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:556) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) at com.sample.ProcessTest.readKnowledgeBase(ProcessTest.java:36) at com.sample.ProcessTest.main(ProcessTest.java:23) When I ran ProcessTest.java with .bpmn file, I get: lang.IllegalArgumentException: Unable to instantiate service for Class 'org.drools.compiler.BPMN2ProcessProvider' at org.drools.util.ServiceRegistryImpl.get(ServiceRegistryImpl.java:161) at org.drools.compiler.BPMN2ProcessFactory.loadProvider(BPMN2ProcessFactory.java:29) at org.drools.compiler.BPMN2ProcessFactory.getBPMN2ProcessProvider(BPMN2ProcessFactory.java:21) at org.drools.compiler.BPMN2ProcessFactory.configurePackageBuilder(BPMN2ProcessFactory.java:12) at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:559) at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) at com.sample.ProcessTest.readKnowledgeBase(ProcessTest.java:33) at com.sample.ProcessTest.main(ProcessTest.java:20) Caused by: java.lang.IllegalArgumentException: Unable to instantiate 'org.jbpm.bpmn2.BPMN2ProcessProviderImpl' at org.drools.util.ServiceRegistryImpl$ReflectionInstantiator.newInstance(ServiceRegistryImpl.java:210) at org.drools.util.ServiceRegistryImpl$ReflectionInstantiator.call(ServiceRegistryImpl.java:202) at org.drools.util.ServiceRegistryImpl.get(ServiceRegistryImpl.java:159) ... 7 more Caused by: java.lang.ClassNotFoundException: org.jbpm.bpmn2.BPMN2ProcessProviderImpl at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at org.drools.util.ServiceRegistryImpl$ReflectionInstantiator.newInstance(ServiceRegistryImpl.java:207) ... 9 more Issue 2: Guvnor 5.2 final unable to display .rf and .bpmn files No error message was given when guvnor is unable to display .rf files.
