Loding pictures into Oracle BLOB or BFILE

Hi,

I am a WINDOWS NT based programmer. I want to load picture into database and I want to access it using Java. I am using BFILE and BLOB for the same. I have created a OS Directory (c:\images) and placed an image file in it(test.jpg). Then I have created a Directory in Oracle Using following command.

create directory "dirimage" as 'c:/images';

Then I got the message 'Directory created'

Then I created a table

create table imagetest(no number(2), bfile_col BFILE);


Then I tried to insert a record using following query

insert into imagetest values(1,BFILENAME('dirimage','c:/images/test.jpg');

************
Then I tried to open that using DBMS_LOB package

CREATE OR REPLACE PROCEDURE seeIfOpenBFILE_procTwo IS
src_loc BFILE:=BFILENAME('dirimage','c:/images/test.jpg');
RetVal INTEGER;
BEGIN
/* Select the LOB, initializing the BFILE locator: */
dbms_lob.open(src_loc, dbms_lob.lob_readonly);
RetVal := DBMS_LOB.ISOPEN(src_loc);
IF (RetVal = 1)
THEN
DBMS_OUTPUT.PUT_LINE('File is open');
ELSE
DBMS_OUTPUT.PUT_LINE('File is not open');
END IF;
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('Operation failed');
END;


***********
When I executed the above procedure I got the error

"Non existing file or directory"

anybody please help me...............

thanks in advance
