Can't get OfficialFile.SubmitFile to work

Question

I'm trying to write a literal SOAP call (I'm integrating from a remote non-windows machine) to submit a file which currently resides in the drop-off library of the site. I created a simple file, testing1.txt, upload and set metadata, then call OfficialFile.SubmitFile with the bytestream and some other fields that I got from this example. No matter what I do, I always get a NotFound error. The request XML I used is below.

What am I doing wrong??

FTA:

There is a group called "Records Center Web Service Submitters for recordcenter" whic hbasically specifies the users allowed to submit a record to the record center via the web service. By default, nobody is a member of this group. To add a user go to "Records Center >Peoples and Groups>Groups" and click on the above mentioned group. Add the user to this group, and the above code works....
