I have been trying to upload my iBooks Author ibook for 2 weeks now and no luck. I received the checkmark and the activity log said I had completed everything, but no appearance in iTunes connect. I have communicated with iBookstore Support, but was told to re-upload and when that didn't work was told to be patient (5 days now).
Finally I found some others in these forums with the same problem and have found the errors in the Package History, so I have tried re-uploading, re-uploading without video, and re-uploading with misc. religious relics in my hands.
My latest Import Error is on the Validation Page and reads:
"Internal error: java.net.MalformedURLException: unknown protocol: bundle schema/20/rng/opf.rng" at Book (MZItmspBookPackage)"
but now the Package History says I am "uploading," which I think means there is just a bad connection, but really I have no idea and even less hope. Also, the Book Assets (book and sample) have a new "repair" button that had never appeared previously. Tried re-applying the assets and uploading but am getting same error message.
So it appears I am losing ground.
Any advice would be appreciated and also, can someone confirm that I should see my submission in itunes Connect within the hour.
My clean install (see above) worked for me, but since then I have received a solution from the Apple iBookstore tech support which, if it works, is sure to be much less painful:
ERROR ITMS-9000: "java.lang.Error: Internal error: java.net.MalformedURLException: unknown protocol: bundle schema/20/rng/opf.rng" at Book (MZItmspBookPackage)
"You can make an update to your settings in iTunes Producer to avoid this issue.
1. Open iTunes Producer
2. From the iTunes Producer menu, open Preferences.
3. Click on the icon for Advanced settings at the right side of the screen.
4. Uncheck the box next to Signiant.
5. Close settings and reattempt your delivery.
You will be notified by email once Signiant is available again."
Plus there's always the firewall solution (see just above) to try before you do anything as drastic as me.
HOPE THIS HELPS.
