jBPM5 has a nifty feature where you can see a workflow in progress and it will show you a graphic of the workflow and show you what node (or nodes) the workflow is on.

Yes, Activiti has the same.

I was interested to know about this utility too. Could you point to the documentation or how to launch the utility?

Hi,

Ready to use it in a Primefaces <p:graphicImage />:


public StreamedContent getProcessImage() {

  String processDefinitionId = taskService.createTaskQuery().taskId(getCurrentTaskId()).singleResult()
    .getProcessDefinitionId();
  String processInstanceId = taskService.createTaskQuery().taskId(getCurrentTaskId()).singleResult()
    .getProcessInstanceId();

  ProcessDefinitionEntity processDefinitionEntity = (ProcessDefinitionEntity) ((RepositoryServiceImpl) repositoryService)
    .getDeployedProcessDefinition(processDefinitionId);

  InputStream imageStream = ProcessDiagramGenerator.generateDiagram(processDefinitionEntity, "png",
    runtimeService.getActiveActivityIds(processInstanceId));

  return new DefaultStreamedContent(imageStream, "image/png");

 }

Regards,
michael
