What exactly do you mean with streaming content? If you're looking for
a way to stream multimedia content (like a shoutcast server would), an
ESB is probably not your best choice.
There are a few possibilities to use streaming content inside ServiceMix
though. Currently, the normalized message contains an XML body and
(optionally) attachments. The XML in the body can be represented by
e.g. a StreamSource and in fact this happens in ServiceMix all the time
(e.g. when servicemix-file reads a file, it will actually send out a
StreamSource). It allows us to transfer really large XML document
without having to load them entirely into memory. The drawback of this
approach is that the stream can only be read once.
As far as the attachments are concerned, these are transferred using the
Java Activation Framework. If you can create a DataSource
implementation to hold the stream you want to transfer, you should be
able to use streaming for attachments as well. In fact, ServiceMix
already has a StreamDataSource class that allows you to send an
InputStream in the attachments. If you want a code example for that,
just take a look at the BinaryFileMarshaler class.

I'm not sure how valid of a question this is... but I was wondering about
streaming resources and SOAs, in particular servicemix. Has anyone tried to
implement any sort of streaming content with servicemix? I'm wondering
about the suitability of SOAs for that sort of task, or if that is something
that you wouldn't want to do, or really isn't applicable for whatever
reason. Has anyone tried or has any thoughts one way or other on the
topic? I didn't seem to find anything that addressed this when I search on
google, but I may not be searching correctly.
