You should be able to do this by writing a custom MessageComposer (org.jboss.soa.esb.listeners.message.MessageComposer). e.g. a "FileInputStreamMessageComposer" that simply opens the file InputStream on the compose() call, attaches the stream as the message payload for processing by the action pipeline, and closes the InputStream on the decompose() call. We'd be happy to receive this back as a contribution :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4136599#...
