--------------------------------------------------------------
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 :

Do someone have ideas about how to solve this problem?
Thanks!
