Yes I am using that to signal the root token but I am thinking now what if I need to signal another token. How do I know which one to signal.
I want to retrieve exactly where I am in a overall process at any one time i.e. which nodes I am at in all execution threads of the process. I am currently performing something like this
| Token token = processInstance.getRootToken()
| String nodeName = token.getNode().getName() ;
Obviously though this is only any good if there is only one route through the process. I would like to return a list of tokens and the associated node name they are currently at.
The reason I am doing this is as follows. I have a client/server setup. The server component is an EJB wrapping the jbpm in a command pattern.
So for example the client would send a SignalProcessDTO holding the transition name, processInstanceId etc to the server. The server will detect the type of payload and run a signal process command. The signal process command will use the info in the DTO to get the process instance and then perform the signal.
I am delivering an adapter jar to the client (a web app). The adapter makes the interface to the server simple. Through the adapter the client is exposed to a very simple API. Essentially it allows them to say one of two things
- Can I make this transition.
- Perform this transition.
. Hence the reason I want to pull back the list of tokens, to determine which "actions" in my adapter can be performed given the currrent state of the process.
