Hi, I am starting to learn Drools and have hit a problem when using the RuleFlow. Whenever I try to run the sample project using Eclipse I get the following error: 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 Any help would be much appreciated.
