Add token with external application

[jeanc]

I have a process that automatically create nodes (node1). I want to add a new node1 with an external application. I try to call the execute method of the forkHandler but I can not get the executionContext.

I put all the code of the execute method in the external application, I can obtain the rootToken, but when I try this code the jpbCxt is always null
ExecutionContext executionContext = new ExecutionContext(rootToken);
JbpmContext jpbCxt = executionContext.getJbpmContext();

Is it possible to do this and how can I do this?

Thanks
