How to get document from all workflow instance

[ecm_daffodil]

Hi All,

how can I get documents / packages / resources from all running workflow instances.
I found some information for workflow package in table alf_child_assoc table,but it is not clear.

I think you have to extend the workflowservice for this purpose.

Have a deeply look to following location in alfresco:

/{http://www.alfresco.org/model/system/1.0}system/{http://www.alfresco.org/model/system/1.0}workflow/{...

All workflows with bpm_packages are stored right there.
