Since you have adapted some test code, I would suggest adapting a complete test that uses custom actions. Once you've parsed the document, I would also recommend instantiating the SCXMLExecutor as described here [1] and using it as described here [2]. -Rahul [1] http://commons.apache.org/scxml/guide/core-engine.html [2] http://commons.apache.org/scxml/guide/core-events.html > 1.
