Thanks for you reply.
ProcessInstance from one node to another node must be through the transition line to just go in jBPM5.3. Now I have a process,it have four node,see diagram, below.

TaskA can transfer to TaskB,because there is a transition from TaskA to TaskB.But there is no transition from TaskB to TaskA in the process model, so processInstance can not transfer from TaskB to TaskA in normal.

Now I want to make the processInstance transfer from TaskB to TaskA in programming,but I don't know whether to support this function in jBPM5.3 and I don't know how to write code to achieve this function.
