Parameters:

resourceName - name of the resource

workflowClass - workflow implementation class to replay

moreWorkflowClasses - optional additional workflow implementation classes

Throws:

java.lang.Exception - if replay failed for any reason.

replayWorkflowExecution

public static void replayWorkflowExecution(java.io.File historyFile,
                                           java.lang.Class<?> workflowClass,
                                           java.lang.Class<?>... moreWorkflowClasses)
                                    throws java.lang.Exception

Replays workflow from a file

Parameters:

historyFile - file that contains a json serialized history.

replayWorkflowExecution

public static void replayWorkflowExecution(java.lang.String jsonSerializedHistory,
                                           java.lang.Class<?> workflowClass,
