java.sql.SQLException: ORA-06550: line 1, column 13: After granting user permission to EXECUTE package -

i've spent months developing java application oracle db back-end. using netbeans ide , oracle 12c on laptop database. pl/sql has been compiled no errors.

after extensive testing (logged in schema owner), attempted add user. created user, logged in sys_dba, using create user e566299 identified temppswrd, granted permission using grant create session , grant execute on c##fai_code.fai_admin_pkg e566299 , received grant succeeded confirmation.

i login application, new user, no errors using following:

private static connection getdbconn(string user, string password) throws sqlexception{         oracledatasource ods = null;         connection dbconn = null;         user = "c##" + user;             ods = new oracledatasource();             ods.seturl("jdbc:oracle:thin:@//localhost:1522/orcl.global.ds.xxxxxxxx.com");             ods.setuser(user);             ods.setpassword(password);             dbconn = ods.getconnection();         return dbconn;     } 

then throws error on first package procedure call:

i'm @ loss, i've tried every possible combination of grant wording, caps, lowercase, single quotes, double quotes, schema owner name prefix c##fai_code.fai_admin_pkg, without fai_admin_pkg, nothing allow new user execute package.

i've spent considerable time on project , near panic no 1 able use it.

question:

why can't newly created user execute package after being granted permission?

edit:

i nullpointerexception on last line call rset.close();, result set never initialized doesn't throw sqlexception

public vector<string> fillbox() throws sqlexception, nullpointerexception{         callablestatement callstatement = null;         resultset rset = null;         string fillbox = "{call fai_admin_pkg.get_end_item_pn(?)}";         vector<string> boxfill = new vector<>();         try{             callstatement = conn.preparecall(fillbox);              callstatement.registeroutparameter(1, oracletypes.cursor);             callstatement.execute();             rset = (resultset) callstatement.getobject(1);              boxfill = buildrsvector(rset);         }         finally{             callstatement.close();             rset.close();         }         return boxfill;     } 

that called here:

vector<string> boxfill = new vector<>();             try{                 boxfill = uiinst.fillbox();             }catch(sqlexception e){                 joptionpane.showmessagedialog(frame, e.getmessage());             }catch(nullpointerexception e){                 joptionpane.showmessagedialog(frame, e.getmessage());                 e.printstacktrace();             } 

here permissions new user...which not include execute on package?? i'm not understanding

problem solved. not having global synonym set or current_schema new user's session set package owner results in calls owners package procedures requiring owner's prefix: <package owner>.<package>.<procedure>. calls making under new user <package>.<procedure> resulting in sqlexception being thrown because compiler package doesn't exist.

additionally, research both global synonyms , user sessions avoid having use quick fix.

thanks help!
