 </fork>
 <join name="join1">
 <transition to="end"></transition>
 </join>

 <join name="join2">
 <transition to="g"></transition>
 </join>

</process-definition>

by given this processdefinition,When TaskNode f and d 's task were all completed ,but the process stoped in the Join2 , and the TaskNode g cann't be accessed , I'm so puzzled by this question.

StartState-->Fork1
Fork1-->node1
Fork1-->Fork2
node1-->Join1
Fork2-->node2
Fork2-->node3
node1-->Join1
node2-->Join1
Join1-->node4
node4-->Join2
node3-->Join2
Join2-->End

the Join1 has 2 arrivingTransitions ,but the each of 2 Transition has different parentFork
the question is coming , node 4 can't be accessed.
How to deal with this quesiton

looks like illegal use of a fork/join... all transitions into a fork need to have the same parent fork... you gave the answer yourself

Thanks for your answers
I know that you said,but the real workflow occurs the scenario that I described.
Can you help me to solve this scenario by jBPM?

uhmmm... not very easily... jBPM certainly will not support this (not sure if any workflowengine supports this)

You have to think out of the box... look at you process from a different perspective... it can almost certainly be moddeled in a different way while adhering to what happens in real life...
