Hi,I've been trying to deploy a simple .bpmn20.xml file, and am not getting much joy either programmatically or through the Probe interface. The BPMN 2.0 file is shown below:
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"

</bpmndi:BPMNEdge>
</bpmndi:BPMNPlane>
</bpmndi:BPMNDiagram>
</definitions>
Everything works just fine when I remove the <import>….. </import>
line from the above, but when the import line is in I get an error when running the deployment code below:
public class RunHelloWorld {
/**
* @param args
*/
public static void main(String[] args) {
// Create Activiti process engine
ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration().buildProcessEngine();
// Get Activiti services
RepositoryService repositoryService = processEngine.getRepositoryService();
RuntimeService runtimeService = processEngine.getRuntimeService();
// Deploy the process definition
repositoryService.createDeployment().addClasspathResource("HelloWorldProcess.bpmn20.xml").deploy();
/**
// Start a process instance
runtimeService.startProcessInstanceByKey("financialReport");
TaskService taskService = processEngine.getTaskService();
List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup("accountancy").list();
taskService.claim((tasks.get(0).getId()), "fozzie");
*/
}
}
The console output I am getting in eclipse is:

SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.

I have tried putting the xerces libraries in java's endorsed directory, and have tried on both java 5 and java 6 - same error in both cases.Has anyone seen this one before, or have any other suggestions ….Many thanks in advance.
