SQL & PL/SQL

The UTL_HTTP.BEGIN_REQUEST function has the following parameters:

UTL_HTTP.BEGIN_REQUEST (

url                           IN VARCHAR2,

method                   IN VARCHAR2 DEFAULT 'GET',

http_version           IN VARCHAR2 DEFAULT NULL,

request_context      IN request_context_key DEFAULT NULL)

RETURN req;

I have an XML file:                               DataFile.XML

I have a web service:                     http://devweb/XferLocation/Xfer.asmx

I have a web service method:          SaveDocument

The method has 2 parameters:      filepath and filename

I want to us the UTL_HTTP.BEGIN_REQUEST function to call the SaveDocument method in order to transfer the XML File to the location specified in the filepath parameter in the SaveDocument method.  Is this possible?  I have the following code, but when I run it I get the following response:

DECLARE
