    My 2 cents:

    1. EJB; given the assumption that you do not intend to wrap your EJB by a Web Service this will end up in RMI calls, which means your client must understand RMI. This may become a problem if your in the public internet because the protocol and ports may be blocked by certain intermediates (firewalls, etc.). You may run into scalability problems. Scale-out (clustering) is much easier if it comes to web protocols like SOAP or REST as load balancers and web servers understand those protocols.
    2. SOAP; definitly an option, as filesize can be up to 10mb you should consider MTOM to transfer the files itself. Embedding the files inside the SOAP message may require you to base 64 encode then, this depends on the file content itself (e.g. binary). In average base 64 enc results in an overhead of factor 1.3 (10mb > 13.33mb).
    3. With REST you will end up with the same problem as with SOAP regarding file encoding.

    To conclude: it depends, I’d look at SOAP + MTOM first and do some tests. You may also consider the “not so hip” protocols like FTP, SFTP, FTPS. If you require guaranteed delivery you may want to look at Managed File Transfer (MFT) concepts: http://en.wikipedia.org/wiki/Managed_file_transfer
