But when I try to kick off a simple process, I get the following error:

Does anyone have any ideas?

Here is my Controller Class:

    ProcessEngine processEngine;
      
       @Autowired
       public void setProcessEngine(ProcessEngine processEngine){
             this.processEngine = processEngine;
          }

        @RequestMapping(value = "/{templatepagename}.html")
        public ModelAndView root(ModelMap model, @PathVariable String templatepagename)
        {
           
            log.debug("In root..index");
            model.addAttribute("templatepagename",templatepagename);
           
           
            log.debug("Running Servlet: TestPage");
   
           RepositoryService repositoryService = processEngine.getRepositoryService();
           ExecutionService executionService = processEngine.getExecutionService();

         
           String deploymentDbid = repositoryService.createDeployment()
                .addResourceFromClasspath("superapp.jpdl.xml")
                .deploy();
          
           log.error("deploymentDbid: " + deploymentDbid);
          
               
           Map<String, Object> variables = new HashMap<String, Object>();
           variables.put("content", "good");
               
           ProcessInstance processInstance = executionService.startProcessInstanceByKey("superapp");
           
            return new ModelAndView("Default",model);
           
           
        }
