Permission to write georaster into filesystem

Question

hi,
i have an oracle sdo_georaster problem. my procedure:
CREATE OR REPLACE PROCEDURE EXPORT_GEORASTER_FILE(
RID NUMBER,
IMG_FNAME VARCHAR,
FILETYP INTEGER,
P_LEVEL NUMBER,
CA_ULX NUMBER,
CA_ULY NUMBER,
CA_LRX NUMBER,
CA_LRY NUMBER
IS
GR SDO_GEORASTER;
FINALSTRING VARCHAR(500);
FT VARCHAR(20);
CA VARCHAR(300);
PLEVEL VARCHAR(40);
BEGIN
IF FILETYP = 0 THEN
FT := 'TIFF';
ELSIF FILETYP = 1 THEN
FT := 'BMP';
ELSIF FILETYP = 2 THEN
FT := 'PNG';
ELSE
FT := 'PNG';
END IF;
IF P_LEVEL IS NULL THEN
PLEVEL := 0;
ELSE
PLEVEL := NULL;
END IF;
IF CA_ULX IS NULL AND CA_ULY IS NULL AND CA_LRX IS NULL AND CA_LRY IS NULL THEN
CA := NULL;
ELSE
CA := 'CROPAREA=('|| CA_ULX || ', ' || CA_ULY || ', ' || CA_LRX || ', ' || CA_LRY ||')';
END IF;
FINALSTRING := 'PLEVEL = ' || P_LEVEL || ', ' || CA;
SELECT GEORASTER INTO GR FROM T99_GEORASTER WHERE ID = RID;
--SDO_GEOR.EXPORTTO(GR, FINALSTRING, FT, 'FILE', IMG_FNAME, 'WORLDFILE', 'FILE', TFW_FNAME);
SDO_GEOR.EXPORTTO(GR, NULL, FT, 'FILE', 'c:\bla1', 'WORLDFILE', 'FILE', 'c:\bla1');
END;
works fine but i'm unable to write in the filesystem. after execute my procedure i get the following message:
SQL> exec EXPORT_GEORASTER_FILE(1,'c:\bla',0,0,null,null,null,null);
BEGIN EXPORT_GEORASTER_FILE(1,'c:\bla',0,0,null,null,null,null); END;
ERROR at line 1:

now i connected wto ora with system (dba) and tried:
SQL> CALL DBMS_JAVA.GRANT_PERMISSION('MDSYS','SYS:JAVA.IO.FILEPERMISSION', 'C:\'
, 'WRITE' );
but i get the exception:
CALL DBMS_JAVA.GRANT_PERMISSION('MDSYS','SYS:JAVA.IO.FILEPERMISSION', 'C:\', 'WR
ITE' )
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:

la1.tfw', 'WRITE' );
CALL DBMS_JAVA.GRANT_PERMISSION('MDSYS','SYS:JAVA.IO.FILEPERMISSION', 'C:\bla1.t
fw', 'WRITE' )
ERROR at line 1:
ORA-29532: Java call terminated by uncaught Java exception:
java.lang.SecurityException: policy table update SYS:JAVA.IO.FILEPERMISSION,
C:\bla1.tfw
i don't know why i get the exception. is there a problem with my java rights?
can anybody help me?
thanks a lot,
michael

Hi Dan!
Thanks for your tip. The roblem was that not my user RASTER (who are owner of sdo_raster) has the WRITE-Permission. So I gave it to MDSYS and RASTER with the following result:
SQL> exec export_georaster_file(1,'e:\bla\bla1',0,NULL,NULL,NULL,NULL,NULL);
-13463
BEGIN export_georaster_file(1,'e:\bla\bla1',0,NULL,NULL,NULL,NULL,NULL); END;
ERROR at line 1:
ORA-13463: error retrieving GeoRaster data: the Permission
(java.io.FilePermission e:\bla\bla1.tfw write) has not been granted to RASTER.
The PL/SQL to grant this is dbms_java.grant_permission( 'RASTER',
'SYS:java.io.FilePermission', 'e:\bla\bla1.tfw', 'write' )
ORA-06512: at "MDSYS.MD", line 1723
