Excetion in creating workflows from java program using sdk

[reachnjain]

Hi

First Problem
I am using sdk and all I am trying to do is to create workflows from my java program but I am getting this error -

Exception in thread "main" org.alfresco.service.cmr.workflow.WorkflowException: 05260000 Format of id jbpm$wf:adhoc is invalid.

MY code -

   public static void createWorkflow(NodeRef fileRef, NodeRef personRef) {
        WorkflowService workflowService = serviceRegistry.getWorkflowService();
        NodeService nodeService = serviceRegistry.getNodeService();
        
         PersonService personService = serviceRegistry.getPersonService();
   
        System.out.println("0");
        fileRef = createNodeRef("db321b03-d442-4c10-a770-0d199da69ab2", "workspace", "SpacesStore");
        System.out.println("1");
        NodeRef workflowNodeRef = workflowService.createPackage(null);
         nodeService.addChild(workflowNodeRef, fileRef, ContentModel.ASSOC_CONTAINS, QName.createQName(NamespaceService.CONTENT_MODEL_PREFIX, "Advert within the workflow package"));
         System.out.println("2");
         Map<QName, Serializable> parameters = new HashMap<QName, Serializable>();
         parameters.put(WorkflowModel.ASSOC_PACKAGE, workflowNodeRef);
         parameters.put(WorkflowModel.ASPECT_WORKFLOW_PACKAGE,workflowNodeRef);
         parameters.put(WorkflowModel.PROP_WORKFLOW_DUE_DATE, new Date(System.currentTimeMillis()));
         parameters.put(WorkflowModel.PROP_WORKFLOW_DESCRIPTION, "Sanket,you are assigned a task");
         parameters.put(WorkflowModel.ASSOC_ASSIGNEE, personRef);
         System.out.println("3"); 
      
         workflowService.startWorkflow("jbpm$wf:adhoc", parameters);
         System.out.println("4");
   }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Second Problem
If I try to do something like this -

 List b = workflowService.getDefinitions();
         List a = workflowService.getAllDefinitions();
         workflowService.getDefinitions();
         

         Iterator i = a.iterator();
         String wid = "";
         while (i.hasNext()) {
            WorkflowDefinition wd = (WorkflowDefinition) i.next();
            System.out.println("workflow name—–>" + wd.getName());
            if (wd.name.equals("jbpm$wf:parallelgroupreview") || wd.name.equals("jbpm$wf:adhoc") ) {
               System.out.println(wd.id);
               wid = wd.id;
            }
         }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I get the following error from the above code -

Can someone suggest me any good resource for workflows? I just need to know about its API and usage…

[reachnjain]

found solution to the 1st problem..
my bad….

It should be
workflowService.startWorkflow("jbpm$1", parameters);

instead of
workflowService.startWorkflow("jbpm$wf:adhoc", parameters);


Still waiting for solution to second problem….
