Thanks Per Sterner, i tried to your suggestion, I removed drools-api dependency from pom.xml its working. -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-Drools-5-4-0-FINAL-and-OSGI-Unable-to-instantiate-service-for-Class-org-drools-concurren-tp4017660p4021691.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Drools 5.4.0.FINAL and OSGI. Unable to instantiate service for Class 'org.drools.concurrent.ExecutorProvider'
Hello, perhaps it is an equinox /eclipse.osgi problem? The drools-api and the drools-core bundle have the same packages 'org.drools.concurrent'. I wrote a little test bundle which only does a dynamic-import like the 'drools-api' bundle. The class org.drools.concurrent.ExecutorProviderFactory can be found with 'Class.forName()'. But the class org.drools.concurrent.ExecutorProviderImpl can't be found. (If I manually require drools-core 'Class.forName()' works for org.drools.concurrent.ExecutorProviderImpl) I have tried eclipse.osgi 3.6.1 , 3.7.2 and the current 3.8.0 Regards, Per Sterner On 01.06.2012 03:29, Mark Proctor wrote: Looks like you have some classpath issues and using the incorrect jar versions.

Hello, I have been using Drools 5.3.0.FINAL until now. I am upgrading my running system with 5.4.0.FINAL. The bundles are all runing. I got some error messages and tried to reduce the problem and created a simple bundle. The code only inserts facts and after 20 facts I get the following error: [ERROR] [System] - Exception in thread Thread-8 java.lang.ExceptionInInitializerError [ERROR] [System] - at org.drools.concurrent.ExecutorProviderFactory.getExecutorProvider(ExecutorProviderFactory.java:12) [ERROR] [System] - at org.drools.rule.constraint.MvelConstraint$ExecutorHolder.clinit(MvelConstraint.java:208) [ERROR] [System] - at org.drools.rule.constraint.MvelConstraint.jitEvaluator(MvelConstraint.java:199) [ERROR] [System] - at org.drools.rule.constraint.MvelConstraint.evaluate(MvelConstraint.java:164) [ERROR] [System] - at org.drools.rule.constraint.MvelConstraint.isAllowed(MvelConstraint.java:124) [ERROR] [System] - at org.drools.reteoo.AlphaNode.assertObject(AlphaNode.java:137) [ERROR] [System] - at org.drools.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:59) [ERROR] [System] - at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:235) [ERROR] [System] - at org.drools.reteoo.EntryPointNode.assertObject(EntryPointNode.java:240) [ERROR] [System] - at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:337) [ERROR] [System] - at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:298) [ERROR] [System] - at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:123) [ERROR] [System] - at org.drools.common.NamedEntryPoint.insert(NamedEntryPoint.java:53) [ERROR] [System] - at de.pelle7.drools.test1.simpletest.SimpleTestDrools$1.run(SimpleTestDrools.java:74) [ERROR] [System] - Caused by: java.lang.IllegalArgumentException: Unable to instantiate service for Class 'org.drools.concurrent.ExecutorProvider' [ERROR] [System] - at org.drools.util.ServiceRegistryImpl.get(ServiceRegistryImpl.java:162) [ERROR] [System] - at org.drools.concurrent.ExecutorProviderFactory$ExecutorProviderHolder.clinit(ExecutorProviderFactory.java:8) [ERROR] [System] - ... 14 more [ERROR] [System] - Caused by: java.lang.IllegalArgumentException: Unable to instantiate 'org.drools.concurrent.ExecutorProviderImpl' [ERROR] [System] - at org.drools.util.ServiceRegistryImpl$ReflectionInstantiator.newInstance(ServiceRegistryImpl.java:213) [ERROR] [System] - at org.drools.util.ServiceRegistryImpl$ReflectionInstantiator.call(ServiceRegistryImpl.java:205) [ERROR] [System] - at org.drools.util.ServiceRegistryImpl.get(ServiceRegistryImpl.java:160) [ERROR] [System] - ... 15 more [ERROR] [System] - Caused by: java.lang.ClassNotFoundException: org.drools.concurrent.ExecutorProviderImpl [ERROR] [System] - at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:506) [ERROR] [System] - at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:422) [ERROR] [System] - at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:410) [ERROR] [System] - at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:107) [ERROR] [System] - at java.lang.ClassLoader.loadClass(Unknown Source) [ERROR] [System] - at java.lang.Class.forName0(Native Method) [ERROR] [System] - at java.lang.Class.forName(Unknown Source) [ERROR] [System] - at org.drools.util.ServiceRegistryImpl$ReflectionInstantiator.newInstance(ServiceRegistryImpl.java:210) [ERROR] [System] - ... 17 more The Rule file: package de.pelle7.drools.test1.users.rules.impl; import de.pelle7.drools.test1.simpletest.*; import org.jbpm.ruleflow.instance.*; rule Funny Rule #1 dialect java when $testObject : TestObjectA( value == 0 ) from entry-point my_entry then System.err.println(New Item: + $testObject); retract($testObject); end If I change the line -- $testObject : TestObjectA( value == 0 ) from entry-point my_entry to -- $testObject : TestObjectA( ) from entry-point my_entry there is no problem.
