    Error with asynchronous execution

    ABIDI Sami Apprentice

      Hello,

       

      I want to execute a jbpm process in asynchronous  continuation mode, and here is a part of the source code that i used :

       

               ProcessEngine processengine = new Configuration().buildProcessEngine();
              
               RepositoryService repositoryservice =  processengine.getRepositoryService();
              
               ExecutionService executionservice =  processengine.getExecutionService();
              
               ManagementService managementService =  processengine.getManagementService();
              
              
               
               ProcessInstance processInstance =  executionservice.startProcessInstanceById("Clef-4");
              
              
               Job job = null;
              
               job =  managementService.createJobQuery().processInstanceId(processInstance.getId()).uniqueResult();
              
              
               managementService.executeJob(job.getId());

       

       

       

      I  would like from this code to execute only the first task of my process.

       

      As  result, I have the first task executed, but I have also an error saying  that jbpm couldn't load my class containing the task even if the task  was executed.

       

      Here is the error message :
