Ok, I find where is problem.

First of all, I had to read log of starting my TomEE server. I found there, that I have problem with one of my EJB class. I inject there resource with transaction manager:

   @Resource
   private UserTransaction userTransaction;

but I forgot to anotate my service EJB by:

@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class TaskService {
  ...
}
