How can i get the human task id defined in bpmn files?

[jayzhang]

List<TaskSummary> tasklst = client.getTasksByStatusByProcessId(processInstanceId, parmlst, "en-UK");

long taskid = tasklst.get(0).getId();

this taskid is not the the human task id defined in bpmn files,but how can i get the  the human task id defined in bpmn files here.

I believe you have the process instance ID. So you can find the process definition id using the instance id first.

Using the process def id, you will need to find the Process object to get the node related information.

Here is what you can do,

String strProcessDefId = JPAProcessInstanceDbLog.findProcessInstance(intProcessInstId).getProcessId(); // Get process def id.
   
readKnowledgeBase(); // Get the knowledge base by feeding it the process name.
 Process objProcess = objKBase.getProcess(strProcessDefId); // Process object.
   for (Node objNode : ((WorkflowProcessImpl) objProcess).getNodes())
   {
     Map<String, Object> hshMetaData = objNode.getMetaData();
     System.out.println(hshMetaData.get("UniqueId"));
    }

Regards.

Thank you！

I solve the problem in this way:

//get session

                              StatefulKnowledgeSession sess = this.jbpm5helper.buildJbpmSession(0);

                              //get processInstance by processInstanceId

                              RuleFlowProcessInstance processInstance=(RuleFlowProcessInstance)sess.getProcessInstance(processInstanceId);

                              //get the id of node To be executed

                              List<NodeInstance> nodeList=(List<NodeInstance>)processInstance.getNodeInstances();

                              int currentNodeId=(int)nodeList.get(0).getNodeId();

hi, may be its too late but i hope this could be helpful for someone else

try this method

List<Long> getHumanTaskNodes(String processIdAsString, RuntimeEnvironment environment) {

    List<Long> nodeIds = new ArrayList<Long>();

    WorkflowProcess workflowProcess = (WorkflowProcess) environment

        .getKieBase().getProcess(processIdAsString);

    for (Node node : workflowProcess.getNodes()) {

        if (node instanceof CompositeContextNode) {

        for (Node inNode : ((CompositeContextNode) node).getNodes())

            if (inNode instanceof HumanTaskNode)

            nodeIds.add(inNode.getId());

        } else if (node instanceof HumanTaskNode)

        nodeIds.add(node.getId());

    }

    return nodeIds;

    }

Here you have all your humanTasks ids
