[ghuazh]

I try to use LocalHumanTaskService,

WorkHandler handler = new WorkHandler(ksession ,LocalHumanTaskService.getTaskService(ksession));

        ksession.getWorkItemManager().registerWorkItemHandler("Human Task", handler);

        if (params.isEmpty()) {

            return ksession.startProcess(processId);

        } else {

            return ksession.startProcess(processId, params);

        }

but I got new exception:

Cannot find named query UnescalatedDeadlines...

but in the Taskorm.xml, it has!

I think the reason is that service needs use only one persistence-unit.

After that, I combinated the human task persistence and processinstance. It solved.

It is very strange!
