I am looking to build a system to allow users on an intranet to upload files to a "repository" server. There is important information that must be stored with each file. It seems to me that SOAP with attachments is a perfect fit for this as it allows me to store the data for the users "request" as well as the file they wish to store and make a web service to handle everything. My concern is that it seems the handling of file uploads is such that the entire file is loaded into memory before sending (on the client side) and before reading ( on the server side) when using the default Java API's for these operations.

I am looking to build a system to allow users on an
intranet to upload files to a "repository" server.
There is important information that must be stored
with each file. It seems to me that SOAP with
attachments is a perfect fit for this as it allows
me to store the data for the users "request" as well as the file
they wish to store and make a web service to handle everything.
My concern is that it seems the handling of file uploads
is such that the entire file is loaded into memory
before sending (on the client side) and before reading
( on the server side) when using the default Java API's
for these operations. I am looking to handle files
in the range of 500MB+ and this of course would be bad to
try and load into memory on each end.


Has anyone tried to do something like this? Is there a better way?
Am I going to have to roll my own entirely to do this?

ftp is the "file transfer protocol", and is designed for handling really large files, including checkpointing and restarting in the middle, etc.
