Hi Deepak,
I am not sure what version of IS your are using. I can tell the way IS 4.6 and above works. When xml document receives in IS it goes to default handler, which is xml content handler and it will generate node.
If you are receiving a non xml document, then it goes to other common content handler. So, you don’t need to write a content handler for that. What you need to do is, on your receiving service create a variable “contentStream” of type object as a input then you should be able to receive the any content which is not xml document.
Let me know if it you have any questions.
