Hi,

   I am a beginer of activiti. After installing the activiti demo project and activiti designer in eclipse, I want to open the

BPMN xml in activiti designer. But some exceptions be throws.

For example , when I double click 'org.activiti.examples.bpmn.callactivity.orderProcess.bpmn20.xml', the exceptions below will be thrown.

org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: org.eclipse.core.internal.resources.ResourceException: Resource '/activiti-engine-examples/src/main/process/org/activiti/examples/bpmn/callactivity/orderProcess.activiti' does not exist.
