Using MTOM to relay attachments

["lauri.siltanen" <la...@gmail.com>]

I have a server and two external systems. The server needs to be able to grab
a file (size ~1GB) from external system A and relay it to external system B.
Is it possible to achieve this by the server opening an input stream from A
and an output stream to B without storing the file on the server?

Hi,

I think use jaxws dispatch-provider mode with StreamSource object you 
may archieve it.
Take a look at [1] &[2]

Hi,
Actually the provider server doesn't care the counterpart is dispatch 
client or a "normal" client.
What the server face is soap message on the wire, I think you can 
transform it to StreamSource and do your relay.
The client and server mode are decoupled.

Hi and thanks for the quick reply.

Using the dispatch-provider approach would require modifying each party in
this transaction. I failed to mention in my initial post that I only have
control over the server. The server receives a DataHandler object is forced
to work with it.

Is there another way to achieve the scenario described in my first post?
