存储过程错误PLS-00201：必须声明标识符“UTL_HTTP”

Question

I am trying to create a stored procedure that request some XML data from a service. I have found several examples on-line and all of them point to using this UTL_HTTP package. However, every time I tried to compile my store procedure with that I get the error:

PLS-00201: identifier 'UTL_HTTP' must be declared

Here is the basic skeleton of the code I want to use.

PROCEDURE GET_XML_DATA2 AS

BEGIN
   DECLARE
   v_soap_request    VARCHAR2(32767);
   v_soap_response   VARCHAR2(32767);

   v_http_request    UTL_HTTP.req; --Fails here
   v_http_response   UTL_HTTP.resp; -- Fails here too
   v_action          VARCHAR2(4000) := '';

BEGIN

    null;

END;

END GET_XML_DATA2;

It fails in the indicated lines and does not compile. I am using Oracle Express Edition and I have already tried to grant my user execute rights to that package. It did not work. What else can I look at? What else could be causing this? Thanks!

As you already figured out yourself, this seems to be a permission problem. Your user does somehow not have access to the UTL_HTTP package. Make sure your user has the EXECUTE permission on the package:

GRANT EXECUTE ON SYS.UTL_HTTP TO my_user;

Note that you might have to do this as SYS.

Using SQL Developer (which I can recommend if you're doing PL/SQL development), see if you can then look at the package somehow. If that does not help, please post the permissions that your user currently has.
