Currently we access them using a third party application that requires iSeries to access the AS/400 (I don't know how the third party application makes the call to the optical drive).
The indexes are created manually by our scanning department. The indexes live on the AS/400. Here is the description of the process from our AS/400 programmer:
The keyword file (TMM0300) will give you the object ID. Use that to go to the link file (TMM0310). That will give you the document ID (aka internal object ID). Use that to get to the document file (TMM0320). That will give you data about the document, including the volume and optical path on which the document resides.
How do I make a connection from my Windows Web Server to the AS/400 to retrieve the images?
Finally, when writing the stream to a file on the WebSphere server, be sure to give it the right MIME type for the specific image format (eg .jpeg, etc.) so the client applications will correctly handle the file when accessing it in WebSphere.
