I'm attempting to write the output of my CoRB job to a filesystem file. I've set the EXPORT-FILE-NAME property in my configuration.
In order to get the CoRB job to actually write to the task I had to set the following variable:
PROCESS-TASK=com.marklogic.developer.corb.ExportBatchToFileTask
It would be nice if CoRB was able to automatically detect that the EXPORT-FILE-NAME property is set, and automatically decide to use the ExportBatchToFileTask as the task processor.
