To view the discussion, visit: https://community.jboss.org/message/799100#799100 -------------------------------------------------------------- Hi, i m using jbpm 5.4 embeded on a web application and i ve a problem after completing a task, getting the next task with the "getTasksAssignedAsPotentialOwner" do not return anything. When i created  the session which contain the process i registered a "LocalHTWorkItemHandler", so i don't think i need to complete it in order to the process to be continued. After the task is completed , i checked on the database and found its status "completed" so i think nothing wrong have happened in completing/persisting operations. i also don't have any exception and nothing happen in the application , i just can't get the next task. h6. The following is the service java class which contain methods used for creating the session and completing the task. public class JbpmAPIUtil {           public static StatefulKnowledgeSession ksession=null;           public static ProcessInstance processInstance;           public static List<LunchedProc> lunchedprocs = new ArrayList<LunchedProc>();           public static List<ProcessInstanceInfo> procsListfrmdb = new ArrayList<ProcessInstanceInfo>();           private static TaskService client;      /*            * Complete a task with a taskid and data for a user            */           public static void completeTask(long taskId, Map<String,String> data, String userId){                     UserTransaction ut=null;                     try {                               ut = (UserTransaction) new InitialContext().lookup( "java:comp/UserTransaction" );                     } catch (NamingException e1) {                               e1.printStackTrace();                     }                     try {                               ut.begin();                     } catch (NotSupportedException e) {                               e.printStackTrace();                     } catch (SystemException e) {                               e.printStackTrace();                     }                       client.start(taskId, userId);                     try {                               ut.commit();                     } catch (IllegalStateException e) {                               e.printStackTrace();                     } catch (SecurityException e) {                               e.printStackTrace();                     } catch (HeuristicMixedException e) {                               e.printStackTrace();                     } catch (HeuristicRollbackException e) {                               e.printStackTrace();                     } catch (RollbackException e) {                               e.printStackTrace();                     } catch (SystemException e) {                               e.printStackTrace();                     }                     ContentData contentData = null;                     if (data != null) {                               ByteArrayOutputStream bos = new ByteArrayOutputStream();                               ObjectOutputStream out;                               try {                                         out = new ObjectOutputStream(bos);                                         out.writeObject(data);                                         out.close();                                         contentData = new ContentData();                                         contentData.setContent(bos.toByteArray());                                         contentData.setAccessType(AccessType.Inline);                               } catch (IOException e) {                                         e.printStackTrace();                               }                     }                     try {                               ut.begin();                     } catch (NotSupportedException e) {                               e.printStackTrace();                     } catch (SystemException e) {                               e.printStackTrace();                     }                     client.complete(taskId, userId, contentData);                     try {                               ut.commit();                     } catch (IllegalStateException e) {                               e.printStackTrace();                     } catch (SecurityException e) {                               e.printStackTrace();                     } catch (HeuristicMixedException e) {                               e.printStackTrace();                     } catch (HeuristicRollbackException e) {                               e.printStackTrace();                     } catch (RollbackException e) {                               e.printStackTrace();                     } catch (SystemException e) {                               e.printStackTrace();                     }     } private static StatefulKnowledgeSession CreateSession(String process){     KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();     kbuilder.add(new ClassPathResource(process), ResourceType.BPMN2);     if (kbuilder.hasErrors()) {         for (KnowledgeBuilderError error : kbuilder.getErrors()) {             System.out.println(">>> Error:" + error.getMessage());         }         System.out.println(">>> Knowledge couldn't be parsed!
