The replay error means that it is getting the same request (or at least two requests with the same nonce within the expiration period), which you shouldn't be getting.
I do notice that the protocol you are using is http instead of https - you may want to change that on the login page and see what happens. I don't think the Adobe signing servers respond well to http
Another month and another similar problem with "ACS Operator Client" (operatorClient.jar): I login:
Authentication URL: https://adeactive.adobe.com/adept
License Signing URL: https://nasigningservice.adobe.com/licenseadmin
Logged in user: email@example.com
Attempted to run a Transaction Report
Start Date: 2/1/12 12:00 AM
End Date: 2/1/12 11:59 AM
Click "Get XML listing"
no data returned and eventually get the following error:
<error xmlns="http://ns.adobe.com/adept" data="E_ADEPT_REQUEST_REPLAY http://nasigningservice.adobe.com/licenseadmin/ManageTransactions"/>
How do I run this "ACS Operator Client" in DEBUG mode and/or how to I get this java appliation to produce an error log?
