Answer 1

Grrr....still not working....I couldn't really get it to work under 8.1.7 or even 9iR1 as the SOAP code depends a lot on XMLTYPE (I assume it's possible to work around, but I don't have the time).
I installed 9iR2 and then created a general purpose database....I then had to do a initxml.sql at xmltype was still not installed with the database; xml loaded but complained about dbms_registries (is this important?).
I then coded up the required soap utility code as described in the article, essentially I used the demosoap package, but renamed it to edmssoap.
I coded up my invokation function/package...tried running it and got this...
SQL> exec dbms_output.put_line(price_service.get_contract_price('10761', '4', '2002-08-13'));
-- I turned this on for debugging in my code...

My wsdl is:

</definitions>
And my invoking function is:
CREATE OR REPLACE PACKAGE BODY price_service AS
FUNCTION get_contract_price(contractkey IN VARCHAR2, productkey IN VARCHAR2, evaldate IN VARCHAR2) RETURN NUMBER IS
req edmssoap.request;
resp edmssoap.response;
BEGIN
req := edmssoap.new_request('calculateContractPrice', 'xmlns="http://mpzarde.palmtreebusiness.com:6060/edms/"');
edmssoap.add_parameter(req, 'param0', 'xsd:int', contractkey);
edmssoap.add_parameter(req, 'param1', 'xsd:int', productkey);
edmssoap.add_parameter(req, 'param2', 'xsd:string', evaldate);
resp := edmssoap.invoke(req, 'http://mpzarde.palmtreebusiness.com:6060/edms/priceCalc',
'urn:com-palmtreebusiness-edms-web-service-PriceCalculationWebService/calculateContractPrice');
dbms_output.put_line(resp.doc.getstringval());
RETURN edmssoap.get_return_value(resp, 'output', 'xmlns="http://mpzarde.palmtreebusiness.com/edms/"');
END;
BEGIN
utl_http.set_persistent_conn_support(TRUE);
END;
What am I missing? Do I need to grant port or something?
TIA,
