“com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'H' (code 72) in prolog; expected '<' ”.

Question

I have a soap service for uploading documents through which I upload multiple documents. The service works fine but once in a while it fails giving the following error - “com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'H' (code 72) in prolog; expected '<' ”. I am not able to find the reason behind this issue. Can anybody tell me the reason this error occurs and the solution for the same. Following is the soap envelope and the server error.

I had similar issue. Your error says that your message don't start with prolog which must be appear before the root element of your xml.
