I think the package you really want to use is UTL_SMTP.  It's not clear if that's what you're doing.  If so, please submit your stored procedure call.  Below is an example of using UTL_SMTP to send an email message.  It is up to the mobile service to convert it to SMS protocol.  I don't think Oracle is going to do that for you.

DECLARE
   c utl_smtp.connection;
   PROCEDURE header(name IN VARCHAR2, header IN VARCHAR2) AS
      BEGIN
         utl_smtp.write_data(c, name || ': ' || header || utl_tcp.CRLF);
      END;
BEGIN
   c := utl_smtp.open_connection('mailserver name');
   utl_smtp.helo(c, 'mailserver name');
   utl_smtp.mail(c, 'email address');
   utl_smtp.rcpt(c, '<phone_number@mobile_providers_domain>');
   utl_smtp.open_data(c);
   header('From', '"Sender" <email address>');
   header('To', '"Recipient" <phone_number@mobile_providers_domain>');
   header('Subject', 'Hello');
   utl_smtp.write_data(c, utl_tcp.crlf || 'Hello,' || utl_tcp.CRLF || utl_tcp.CRLF || 'This is a test message.');
   utl_smtp.close_data(c);
   utl_smtp.quit(c);
END;

Likely UTL_HTTP is the correct package, as most web based SMS gateways (not SMTP) expose a HTTP based service.

Provide your code so we can see it?

Dear Sadler,
I have used UTL_SMTP for the same purpose but now we have changed the SMS provider and he does not support email to SMS so we have to change the process by shifting to HTTP post method that's why I am trying to use this package. Here is code which I am using for this purpose. If I send request for www.google.come it returns the page successfully.
DECALRE
   text_str varchar2(5000);
   text_sms varchar2(2000) := 'http://www.kaamilsms.com/kaamil/custapi/sendTextSMS_http.cfm?usrName=xx&usrPass=xx&msgLNG=eng&msgSenderID=xx&gsmNumber=966509418646&msgtext=This is a test english message';
begin
   text_str := utl_http.request(text_sms);
end;
/

Thanks and regards

Well, the UTL_HTTP package seems to be working for you.  I believe Kaamil is trying to tell you that the parameter value you're sending to them is not formed correctly.  Perhaps one or more of your variable values is blank?

You should URL encode the string before sending. Otherwise, I think UTL_HTTP.REQUEST will do I am not sure what, such as remove the spaces. It is possible you having problems related to proper encoding.


select utl_url.escape('http://foo.com/api?arg=this is a test') from dual;


text_str := utl_http.request(utl_url.escape('http://foo.com/api?arg=this is a test'));

I figured out that any special character which is part of the SMS message cause this error.

Is this utl_url package available in 8i?

Thanks a lot for the help.

No, it is 9i and up, you can write your own, though
