Post to a servlet from a PL/SQL procedure

Question

I would like to know if it's possible to post a form from pl/sql. There is this servlet that does stuff but it doesn't have any api i can call so i can only post the parameters to the servlet using an html form. Each form element is added to the http header so i just have to create a header and send it to the servlet but i don't really know how to do this using pl/sql.

Answer 1

Meanwhile i have found the solution myself.
This is the snippet that sends a post form to a webpage:
declare
v_url varchar2(400) := 'myUrl';
v_post varchar2(4000);
HTTP_REQ    utl_http.REQ;
HTTP_RESP   utl_http.RESP;
begin
v_post := 'param1=value1&param2=value2';
HTTP_REQ := utl_http.BEGIN_REQUEST(v_URL, 'POST', 'HTTP/1.1');
utl_http.SET_HEADER(HTTP_REQ, 'Content-Type', 'application/x-www-form-urlencoded');
utl_http.SET_HEADER(HTTP_REQ, 'Content-Length', length(v_post));
utl_http.WRITE_TEXT(HTTP_REQ, v_post);
HTTP_RESP := utl_http.GET_RESPONSE(HTTP_REQ);
end;This post the parameters and values from v_post to the url. In the HTTP_RESP i get the status_code so i can check if it's ok or there was a server error (code 500).
