Help me with ordsys.ordimage

Question

i have problems when using interMedia to import images on DB server.
i have 2 tables :
create table t( pic_id number, pic_ord ordsys.ordimage);
create table demo(id number, b BLOB);
create directory PICDIR as 'd:\pic'; --- this directory is correct on server;
grant read on directory PICDIR to PUBLIC;
commit;
DECLARE
img ordsys.ordimage;
ctx raw(4000);
BEGIN
insert into t values(1,ordsys.ordimage.init());
select pic_ord into img
from t
where pic_id=1 for update;
img.setSource('FILE','PICDIR','1.bmp');
-- set source is OK,but the following IMPORT() raises exceptions
img.import(ctx);
img.setProperties();
update t
set pic_ord=img
where pic_id=1;
commit;
end;
ERROR at line 1:
ORA-29400: data plug-in error IMG-00002:

=====================================
after millions of times trying that ,i tried to load the file into a blob,
and copy from blob to ordsys.ordimage.source.localdata(this is a blob);
see:
DECLARE
l_blob blob;
l_file bfile;
BEGIN
delete from t;
insert into demo values(1,EMPTY_BLOB())
returning b into l_blob;
l_bfile := bfilename( 'PICDIR', '1.bmp');
dbms_lob.fileopen( l_bfile );
dbms_lob.loadfromfile( l_blob, l_bfile, dbms_lob.getlength( l_bfile ) );
dbms_lob.fileclose( l_bfile );
end;
succeed!
SQL> select id, dbms_lob.getLength(b) from demo;
ID DBMS_LOB.GETLENGTH(B)
1 1963494
===================================================
then i copy the blob into t.pic:
insert into t
( select id, ordsys.ordimage(ordsys.ordsource(b,NULL, NULL, NULL, SYSDATE, 1 ),
NULL, NULL, NULL, NULL, NULL, NULL, NULL )
from demo
==================================================
then i check the blob's size in ordimage,and use setProperties() :
declare
img     ordsys.ordimage;
ctx     raw(4000);
begin
select pic into img
from t
where pic_id= 1 for update;
dbms_output.put_line('ord blob length:'||dbms_lob.getLength(img.source.localdata));
img.setProperties();
update t
set pic=img
where pic_id=1;
commit;
end;
ord blob length:1963494
declare

Answer 1

Thank you!
My db version is 9.0.1.0.1
interMedia version 9.0.1.0.1
i thought it's the installation error, but i have tried the /ord/im/admin/imchk.sql.
Both version and components are VALID.
JServer setup is correct.
the JServer java objects are all valid.
ORDSYS.ORDPLUGINS is VALID.
but the codes can still not run!!
i don't know what's wrong.
please help me!
thank you!!
