Oleg,
Thanks for the pointer. I implemented the RequestEntity and the
streaming is working fine if I know the content length. However the
content is generated dynamically from business data. As is specified
in the RequestEntity, my getContentLength() returns -1. However I'm
getting the following exception. Do I need to implement anything else?
Thanks,
