I have deployed my work flow in Jbpm guvnor and started a new workflow. Each user task has a task form. Then I access task form via Rest API  and complete the task. All works fine and data is saved to database. Then I am trying to get user filled data in task form through java code. But it doesn't work..

            Content content = taskService.getContent(task.getTaskData().getDocumentContentId());

            out.print("content.getId():::"+content.getId());

             Object obj = null;

             ByteArrayInputStream bInput = new ByteArrayInputStream(content.getContent());

             ObjectInputStream inputStream = new ObjectInputStream(bInput);

             obj = inputStream.readObject();

              out.print("...."+obj);

               int c;

               for(int y = 0 ; y < 1; y++ ) {

                     while(( c= bInput.read())!= -1) {

                     out.println("c"+c);

                     }

                    // bInput.reset();

                  }

        } catch (Exception e1) {

            // TODO Auto-generated catch block

            e1.printStackTrace();

        }

Can anyone say how to get task form filled data through the java code??
