Question

We know there are out of the box SharePoint web service

Answer 1

May be I missed something... but when you let users upload files to your J2EE server, wouldn't you be writing the uploaded content to a temp directory first and then stream it to the server?

As you write the buffers immediately to the disk, you wouldnt have any issues with memory limitations.
