How to signal process from external system?

rufjan Nov 30, 2011 9:28 AM

Hi All, I would like to create a process which will have two human tasks and then it will wait for sending signal from external system. So I've created two human tasks which work perfect and then I've "Signal event" which EventType is "dummyType", name is "Signal". Process waits for signal, but the question is, how should I invoke that signal from external system? I would like to use rest webservices, but which one should I choose? How the url should be built?

Thank you for help!

Best regards,

Michal

Michal, if you consider to use jBPM console (or its server part) you can give it a try with REST interface. Once deployed you can use following URL to display all available resources of the REST interface:
http://localhost:8080/gwt-console-server/rs/server/resources
If I recall correctly you should use /gwt-console-server/rs/process/tokens/{id}/transition to signal you process instance where id is the process instance id and use 'signal' query parameter to provide event data to the signal method. When using this approach it will use 'signal' as event type.

So I would try following url to signal:
http://localhost:8080/gwt-console-server/rs/process/tokens/{id}/transition?signal=data
