Understood. I still don't fully understand how this works in Axis, but if you really need to solve this problem you should dive into Axis' support for streaming messages.

If someone knows more, can they please post it here and on the Wiki? http://nagoya.apache.org/wiki/apachewiki.cgi?action=edit&id=AxisProjectPages/StreamingService
