Application Development Software

hi i'm currently researching on oracle doc capture and oracle distributed doc capture products,

currentyly i've problem in the commiting feature from the web oddc client,
after i scanned documents, i click send, (im using text commit profile)
but when i check in the commit folder at the capture server, there's nohting in it
(i've use c:\odc\commit for the commit folder)

but there's something in the IIS webcapture clientaccess folder (C:\Program Files\Oracle\Document Capture\WebPages\ClientAccess)
its a .PAK file name, when i open it in winrar, its indeed the document that i scanned and send from the client.

but why is it stored in here? what's with the .PAK format, and how to configure the settings properly for storing
files with its proper format (TIFF, JPG, PDF) in the server ??

i'm using recent odc and oddc from oracle, in windows 2003.

any help will be appreciated, if this works, i'll try commiting to ucm (so far it isnt working also)
