Granting privileges doesn't work

Question

I have created package with couple of procedures, which are working perfectly, when I access package using my own username and password (package owner's). To access my package from another user ora17, I granted privileges:

grant execute on package_name TO ora17;

then from ora17 user I ran following:

CREATE SYNONYM package_name FOR LOGIN.package_name;

following teacher's instructions. Trying to access my program from browser, f.e. using url: https://somehost/pls/st12/package_name.customers I am getting following error:

Thu, 28 Dec 2017 15:12:19 GMT

Failed to parse target procedure 
package_name.customers: PROCEDURE DOESN'T EXIST

What am I doing wrong here?

UPD: executing

describe package_name;

it gives me error:

ORA-04043: object "LOGIN"."PACKAGE_NAME" does not exist

Answer 1

Solution for this was simple, I just should have put owner's username instead of LOGIN here:

CREATE SYNONYM package_name FOR LOGIN.package_name;
