responding with data

[Larry Gilliam <lg...@innovim.com>]

Hello,

How can I respond to a web service call with a stream of data?
Can I use SwA (SOAP with Attachements)?
Can I use SwA when the request is SOAP, but just return an
octet-stream when the request is REST?

Thanks for any info.

I use MTOM attachments. (I don't use Axis2 in the server, but I assume
the mechanism would be identical as with JAX-WS)

Using MTOM allows me to stream large files (hundreds of MB or GB)
outside of the XML SOAP envelope.
The element definition does not change

    <xsd:element name="theAttachment" type="xsd:base64binary"
xmime:expectedContentTypes= "*/*"/>

where xmime refers to the namespace
   xmlns:xmime="http://www.w3.org/2005/05/xmlmime"

I define my own implementation of DataSource that uses piped streams
(a pir of PipedOutputStream/PipedInputStream) to be able to free my
service thread -and return the SOAP call- and let  the streaming occur
in its own thread.

I have no idea how Axis2 would send the attachment if the original
request is REST.
