SQL & PL/SQL

Hi,
i need advice.


utl_http.set_body_charset('ISO-8859-2');
http_req := utl_http.begin_request(x_url, 'POST', 'HTTP/1.0');
utl_http.set_header(http_req, 'Content-Type', 'text/xml');
utl_http.set_header(http_req, 'Content-Length', length(env));
utl_http.set_header(http_req, 'SOAPAction', action);

dbms_output.put_line('postupne odosleme request');

procstep := 'postupne odosleme request';
offset := 1;
LOOP
env2 := dbms_lob.substr(env, amount, offset);
EXIT WHEN env2 IS NULL;
offset := offset + amount;
utl_http.write_text(http_req, env2);
END LOOP;
http_resp := utl_http.get_response(http_req);
resp.doc := NULL;
BEGIN
LOOP
j:=j+1;
utl_http.read_text(http_resp, env2);
resp.doc := resp.doc || env2;
END LOOP;
EXCEPTION
WHEN
OTHERS THEN
NULL;
END;
utl_http.end_response(http_resp);
