Webservice call from PL/SQL

Question

Hi,
I am trying to call a RESTful webservice from a PL/SQL block, I am using a 9i DB.
Th webservice accepts a single form-field argument, which is XML string input, below is the code where I am trying to make a call.
I am getting back a very weird error as if the necessary arguments are not being passed, I am not sure if I am passing the parameter in the correct way.
     t_request_body := 'request=<?xml version="1.0"?>
<serviceRequest>
          <auth>
               <ApplicationID>abc</ApplicationID>
               <wsPassword>123456</wsPassword>
          </auth>
          <Request>
               <Processor>BAMS</Processor>
               <MerchantNumber>AD8360-05</MerchantNumber>
               <NAME>FirstName</NAME>
               <Email>[email protected]</Email>
               <Address1>1234 SOME Street</Address1>
               <Address2></Address2>
               <City>SOME City</City>
               <State>IN</State>
               <Zip>12345</Zip>
               <Country>US</Country>
               <Phone>123-123-1234</Phone>
               <Amount>1.00</Amount>
               <OrderNumber>ORDER123</OrderNumber>
          </Request>
     </serviceRequest>';
url := 'https://RestfulWebserviceCall';
UTL_HTTP.SET_RESPONSE_ERROR_CHECK( TRUE );
UTL_HTTP.SET_DETAILED_EXCP_SUPPORT( TRUE );
UTL_HTTP.SET_COOKIE_SUPPORT( TRUE );
--UTL_HTTP.SET_TRANSFER_TIMEOUT( 30 );
--UTL_HTTP.SET_FOLLOW_REDIRECT( 3 );
UTL_HTTP.SET_PERSISTENT_CONN_SUPPORT( TRUE );    
t_http_req:= UTL_HTTP.BEGIN_REQUEST (url=> url, METHOD => 'POST');
UTL_HTTP.SET_HEADER(t_http_req, 'Content-Type', 'text/xml charset=UTF-8');
UTL_HTTP.SET_HEADER(t_http_req, 'Content-Length', LENGTH(t_request_body));
UTL_HTTP.WRITE_TEXT(t_http_req, t_request_body);
t_http_resp:= UTL_HTTP.GET_RESPONSE(t_http_req);
endLoop := FALSE;
LOOP
EXIT WHEN endLoop;
BEGIN
UTL_HTTP.READ_LINE( t_http_resp, buffer, TRUE );
IF (buffer IS NOT NULL) AND LENGTH(buffer)>0 THEN
     DBMS_OUTPUT.PUT_LINE('Output '||buffer);
END IF;
EXCEPTION WHEN UTL_HTTP.END_OF_BODY THEN
endLoop := TRUE;
END;
END LOOP;
UTL_HTTP.END_RESPONSE(t_http_resp);
EXCEPTION
WHEN UTL_HTTP.END_OF_BODY THEN
UTL_HTTP.END_RESPONSE (t_http_resp);
END;
Thanks for your help in advance.
