I have this script to use UTL_HTTP.

DECLARE

req   UTL_HTTP.REQ;

resp  UTL_HTTP.RESP;

value VARCHAR2(1024);

BEGIN

  req := UTL_HTTP.BEGIN_REQUEST('http://dba-oracle.com');

  UTL_HTTP.SET_HEADER(req, 'User-Agent', 'Mozilla/4.0');

  resp := UTL_HTTP.GET_RESPONSE(req);

  LOOP

    UTL_HTTP.READ_LINE(resp, value, TRUE);

    dbms_output.put_line(value);

  END LOOP;

  UTL_HTTP.END_RESPONSE(resp);

EXCEPTION

  WHEN UTL_HTTP.END_OF_BODY THEN

    UTL_HTTP.END_RESPONSE(resp);

END;

/

I adjusted the script to use the Oracle Wallet using https with certificate:

declare

  req    utl_http.req;

  resp   utl_http.resp;

  value  varchar2(1024);

  l_url  varchar2(2000) := 'https://******.*****.nl:443';

  l_data clob;

  cursor c_data is

    select clobdata

    from   post_file;

begin

  open c_data;

  fetch c_data into l_data;

  close c_data;

  utl_http.set_proxy('168.0.0.1:8080', '');

  utl_http.set_wallet('file:C:\wallet', '*******');

  req := utl_http.begin_request(l_url);

  utl_http.set_header(req, 'User-Agent', 'Mozilla/4.0');

  utl_http.set_header(req, 'content-length', length(l_data));

  utl_http.write_text(req, l_data);

  resp := utl_http.get_response(req);

  loop

    utl_http.read_line(resp, value, true);

    dbms_output.put_line(value);

  end loop;

  utl_http.end_response(resp);

exception

  when utl_http.end_of_body then

    utl_http.end_response(resp);

end;

/

This works fine and I get a good response.

But when I put it in a procedure I get:

HTTP Error 403.7 - Forbidden: SSL client certificate is required.

Internet Information Services (IIS)

How is this possible and how can I solve this?

I now created the procedure in the sys scheme and it works there. So the question is: what rights are missing for the user scheme, which makes it impossible to use the procedure, but possible doing it by script?

    Don't you think it would be helpful to post the procedure?

    Thank you for your reply. I didn't think so because it is the same as the script. But here it is:

    create or replace procedure sp_post_https

    as

      req    utl_http.req;

      resp   utl_http.resp;

      value  varchar2(1024);

      l_url  varchar2(2000) := 'https://******.*****.nl:443';

      l_data clob;

      cursor c_data is

        select clobdata

        from   post_file;

    begin

      open c_data;

      fetch c_data into l_data;

      close c_data;

      utl_http.set_proxy('168.0.0.1:8080', '');

      utl_http.set_wallet('file:C:\wallet', '*******');

      req := utl_http.begin_request(l_url);

      utl_http.set_header(req, 'User-Agent', 'Mozilla/4.0');

      utl_http.set_header(req, 'content-length', length(l_data));

      utl_http.write_text(req, l_data);

      resp := utl_http.get_response(req);

      loop

        utl_http.read_line(resp, value, true);

        dbms_output.put_line(value);

      end loop;

      utl_http.end_response(resp);

    exception

      when utl_http.end_of_body then

        utl_http.end_response(resp);

    end;

    This is the exact response:

    Where is your database server? On the windows machine where c:\wallet is?

    Yes, both on the same machine (Microsoft Windows Server 2008 R2 (64-bit)).

    Oracle Database 11g Enterprise Edition Release 11.2.0.1.0

    Are you running these as the same user - with the correct ACL applied?

    Yes, same user and correct ACL applied. Also ran by sys and sysman, same results.

    Sorry, I've run out of ideas at the moment - but I'll keep thinking about it.
