If I define a service task,and I assign a class to this service task, this class implements the interface of ActivityBehavior,

You can use a "JavaDelegate" instead, this hides some internal flow-logic and allows you tu just execute some code as part of the process, leaving the rest in the hands of activiti. Unless, off course, you want finer-grained control, in that case:

I mean that If i want a finer-grained control, I must assign the outgoingtransition in this class, it can be taken to the right task from assigned outgoingtransition?
the codes are as follows:
PvmTransition pvmTransition=execution.getActivity().getOutgoingTransitions().get(0);
execution.take(pvmTransition);

Best approach for this is to put a exclusive gateway right after the (service)task that makes the decision where the execution should go next. This can be done setting a variable in the service task and evaluating it using conditionExpressions on the outgoing sequence flows on the gateway.
