Webservices with pl/sql

Question

In all examples for webservices i have seen java is used.
Is it possible to make a webservice in pl/sql without the use of java?

Answer 1

Hi Folks,
I have successfully deployed the PL/SQL calling web services following example in the link provided above. However, I face a problem whereby I need to pass in 2 parameters. The example given is only passing 1 parameter. Can somebody tell me how can I pass in 2 parameters? Appreciate if you can help.
CREATE OR REPLACE PACKAGE time_service AS
FUNCTION get_local_time(zipcode IN VARCHAR2) RETURN VARCHAR2;
END;
CREATE OR REPLACE PACKAGE BODY time_service AS
-- Location of Web service definition
-- http://www.alethea.net/webservices/LocalTime.asmx?WSDL
FUNCTION get_local_time(zipcode IN VARCHAR2) RETURN VARCHAR2 IS
req demo_soap.request;
resp demo_soap.response;
BEGIN
req := demo_soap.new_request('LocalTimeByZipCode',
'xmlns="http://www.alethea.net/webservices/"');
demo_soap.add_parameter(req, 'ZipCode', 'xsd:string', zipcode);
resp := demo_soap.invoke(req,
'http://www.alethea.net/webservices/LocalTime.asmx',
'http://www.alethea.net/webservices/LocalTimeByZipCode');
RETURN demo_soap.get_return_value(resp, 'LocalTimeByZipCodeResult',
'xmlns="http://www.alethea.net/webservices/"');
END;
BEGIN
* Since the Web service resides outside of the firewall, we need to set
* the proxy in the current session before invoking the service.
utl_http.set_proxy('www-your-proxy', NULL);
utl_http.set_persistent_conn_support(TRUE);
END;
