How do I make the webutil file transfer works correctly?

Question

Hello,
I'm using Oracle 10g Database and form builder in developer suite 10g release 2. Running on Windows XP SP2.
I've created a database user, executed the create_webutil_db.sql , and created a table as below:
CREATE TABLE DOCS
(DOC_ID VARCHAR2(15) NOT NULL,
DOC_IMAGE BLOB,
TEXT_DESCRIPTION CLOB,
FILENAME VARCHAR2(80),
FILE_SIZE NUMBER NOT NULL,
CONSTRAINT PK_DOCS PRIMARY KEY (DOC_ID)
I've created two buttons in the from, one for upload and one for download
the upload code:
DECLARE
     fname VARCHAR2(1000);
     fext VARCHAR2(1000);
     result BOOLEAN;
BEGIN
     fname := Client_Get_File_Name(null,null,null,null,OPEN_FILE,TRUE);
     fext := fname;
     WHILE instr(fext,'.') <> 0 LOOP
          fext := substr(fext,instr(fext,'.')+1);
     END LOOP;
     IF LOWER(fext) <> 'doc' THEN
          message('Only Microsoft Word Document (*.doc) can be uploaded');
     ELSE
          result := Webutil_File_Transfer.Client_To_DB
          (trim(fname),'DOCS','DOC_IMAGE','DOC_ID = ' || '''' || :DOC_ID || '''');
          IF result THEN
               message ('Upload success');
               :FILENAME := fname;
               :FILE_SIZE := WebUtil_file.file_size(:FILENAME);
               WHILE instr(:FILENAME,'\') <> 0 LOOP
                    :FILENAME := substr(:FILENAME,instr(:FILENAME,'\')+1);
               END LOOP;
          ELSE
               message ('Upload failed');
          END IF;
     END IF;
END;
and the download code:
DECLARE
     result BOOLEAN ;
BEGIN
     IF :FILE_SIZE > 0 THEN
          result := Webutil_File_Transfer.DB_To_Client
     (trim(Client_Get_File_Name(null,:FILENAME,null,null,SAVE_FILE,TRUE)),'DOCS','DOC_IMAGE','DOC_ID = ' || '''' || :DOC_ID || '''');
          IF result THEN
               message ('Download success');
          ELSE
               message ('Download failed');
          END IF;
     ELSE
          message('No file to download');
     END IF;     
END;
I can upload the file to the database, and download the file.
However, the file being downloaded is corrupted. I don't know why this will happen. I've tried to rebuild the form, re-attach the webutil library, rebuild the database users and tables, but all these doesn't work.
Please help, thank you.
