[rules-users] RE: 4.0.0-M2: RuleFlow "CannotResolveClassException" error

_____________________________________________ From: Anstis, Michael (M.) Sent: 09 May 2007 09:51 To: 'Rules Users List' Subject: 4.0.0-M2: RuleFlow "CannotResolveClassException" error Hi, I added the Eclipse 4.0.0-M2 plugin and created an example project; changing the class path to reference core-4.0.0-M2, compiler-4.0.0-M2 and dependencies. I modified the example to include Ruleflow based upon the wiki entry for 4.0.0-M2 and created a simple RuleFlow with two RuleGroups ("one" and "two") one for each rule in the Sample.drl. I also modified the DRL to include Rule-Group attributes ("one" and "two"). Unfortunately when running within Eclipse I received the following error:- com.thoughtworks.xstream.alias.CannotResolveClassException: org.drools.eclipse.flow.ruleflow.core.RuleFlowProcessWrapper : org.drools.eclipse.flow.ruleflow.core.RuleFlowProcessWrapper at com.thoughtworks.xstream.mapper.DefaultMapper.realClass(DefaultMapper. java:35) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.XmlFriendlyMapper.realClass(XmlFriendl yMapper.java:44) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.ClassAliasingMapper.realClass(ClassAli asingMapper.java:49) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.DynamicProxyMapper.realClass(DynamicPr oxyMapper.java:46) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.ArrayMapper.realClass(ArrayMapper.java :70) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.MapperWrapper.realClass(MapperWrapper. java:18) at com.thoughtworks.xstream.mapper.CachingMapper.realClass(CachingMapper. java:27) at com.thoughtworks.xstream.core.TreeUnmarshaller.start(TreeUnmarshaller. java:95) at com.thoughtworks.xstream.core.ReferenceByIdMarshallingStrategy.unmarsh al(ReferenceByIdMarshallingStrategy.java:12) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:552) at com.thoughtworks.xstream.XStream.unmarshal(XStream.java:540) at com.thoughtworks.xstream.XStream.fromXML(XStream.java:490) at org.drools.compiler.ProcessBuilder.addProcessFromFile(ProcessBuilder.j ava:54) at com.sample.DroolsTest.readRule(DroolsTest.java:67) at com.sample.DroolsTest.main(DroolsTest.java:22) Suspecting I've missed something obvious can you advise?
