Received WS-I BP non-conformant Unquoted SoapAction HTTP header

It is actually a simple problem where you do not give a quote (") String in your SOAPAction HTTPHeader. It takes time for me to googling the solution because whenever I query Google, it seems like no direct discussion about the problem. Here I write down the solution directly for you.

Just put String SOAPAction = "\"getUserProfilePhoto\"" . This \" will add quotes to your HTTPHeader and the irritating warning will gone forever.
