We are using Javelin flows to tie all the operations together and which are then launched as an action in the generator.
Original the configuration was that the Portal server was only running the portal and the Javelin jobs would be executed on the application server for performance reasons.
If the flow attached to the generator is using sub-flows, then we run into the problem.
JavelinExecutor refuses to execute flows on network drives.
Test Data Manager
When running Javelin as a process launched from the portal the session runs in a special system session in which User session mapped drives do not exist.
The files must be local to the TDM portal to run.
