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