Hi Garrett,

I'm guessing this is probably caused by MessageIDGenerator.

HAPI uses a file on disk, created in your application's working directory
by default to generate sequential control IDs for messages it sends. I'm
guessing your application may not have write permission to the working
directory.

Note that you can override the location on disk where this file is stored
by specifying a new one in the system property "hapi.home". Looking over
the JavaDoc for MessageIDGenerator, this is pretty lacking. I'm making a
note to myself that this needs to be cleaned up.

Cheers,
James
