Hi all.

I'm trying to develop e simple application with activiti engine api.
I have intsllaed the demo application, started up, and lunch my application.

My code is


public void init(ServletConfig config) throws ServletException {
super.init(config);
processEngine = ProcessEngines.getDefaultProcessEngine();
}


protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    PrintWriter out = response.getWriter();

    RepositoryService repositoryService = processEngine.getRepositoryService();
    RuntimeService runtimeService = processEngine.getRuntimeService();

    Deployment deployment = repositoryService.createDeployment().addClasspathResource("C:/Users/Simone/workspace/ProvaNewDesigner/target/classes/diagrams/bpmn2_diagram.bpmn20.xml").deploy();

    ProcessInstance processInstance = runtimeService.startProcessInstanceByKey("helloworld");

    out.println("Started Process instance id " +processInstance.getProcessInstanceId());

}


at the point

RepositoryService repositoryService = processEngine.getRepositoryService();

an excpetion is trow.
