[General] Any experience with large attachment in an SOA platform ?

[cdeneux]

It's not very difficult.
On the reception side, just create an InputStream as Wrapper of 2 "buffers":
    - one base on the existing one, holding all bytes in memory,
    - another one based on a FileOutputStream, saving all bytes on disk. This buffer is used in combination with a size threshold.
On the sending side, we can use same concepts
