Error ora-20001 when install a developped application

Hello,

I've developped a small application with oraclexe 10.2.0.1 and apex v21 (embedded apex on oraclexe) under windows 7 ultimate.

The application where developped and used several times with no issues.

Then I made an "export" and the file name was: f100........sql .

Serveral days after I had the necessity to import this application into the same system.

After few minutes I had a bad oracle message:

ora-20001: erreur GET_BLOCK. ORA-20001: ERREUR GET_STMT. ORA-20001_ L'EXECUTION DE L'INSTRUCTIONA ECHOUé. ORA-06550: LIGNE 45 ,COLONNE 38:PLS-00103: SYMBOLE etc...

My question is: How to find the log file witch should produced when we import an developped APEX application...

RMK: in others version of apex 32...321 the log is located in c:\program files\oracle\inventory...

but on ORACLEXE there is no "inventory" directory...

any ideas?

thanks
