Error asserting objects using JamVM ----------------------------------- Key: JBRULES-896 URL: http://jira.jboss.com/jira/browse/JBRULES-896 Project: JBoss Rules Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: 4.0.0.MR2 Environment: Linux with JamVM and GNU Classpath Reporter: Roberto Carballedo Assigned To: Mark Proctor When I try to assert an objecto to the working memory a exception is thrown. It seams that there is a problem when the shadow fact proxy. The detailed Exception trace is: org.drools.RuntimeDroolsException: Error creating shadow fact for object: TemperatureSensor_1 [0.0] at org.drools.base.ClassObjectType.getShadow(ClassObjectType.java:164) at org.drools.reteoo.ObjectTypeNode.assertObject(ObjectTypeNode.java:153) at org.drools.reteoo.Rete.assertObject(Rete.java:121) at org.drools.reteoo.ReteooRuleBase.assertObject(ReteooRuleBase.java:201) at org.drools.reteoo.ReteooWorkingMemory.doAssertObject(ReteooWorkingMemory.java:70) at org.drools.common.AbstractWorkingMemory.assertObject(AbstractWorkingMemory.java:724) at org.drools.common.AbstractWorkingMemory.assertObject(AbstractWorkingMemory.java:548) at flexeo.ruleEngine.FlexeoRuleLoader.main(FlexeoRuleLoader.java:47) Caused by: org.objenesis.ObjenesisException: java.lang.reflect.InvocationTargetException at org.objenesis.instantiator.basic.ObjectStreamClassInstantiator.newInstance(ObjectStreamClassInstantiator.java:51) at org.drools.base.ClassObjectType.getShadow(ClassObjectType.java:160) ...7 more Caused by: java.lang.reflect.InvocationTargetException at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:372) at org.objenesis.instantiator.basic.ObjectStreamClassInstantiator.newInstance(ObjectStreamClassInstantiator.java:48) ...8 more Caused by: java.io.InvalidClassException: flexeo.Device.TemperatureSensorShadowProxy; No public zero-argument constructor at java.io.ObjectStreamClass.newInstance(ObjectStreamClass.java:931) at java.lang.reflect.Method.invokeNative(Native Method) ...10 more  I changed the default objenesis instantiator, because JamVM doesn't support Sun's ReflectionFactory class, but I can't find a solution -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
