Error in using DBMS_LOB Package

Question

Hi,
I am attaching a PDF File through a database procedure as shown below
create or replace procedure load_document(document_id in number, filename IN varchar2, doc_desc IN VARCHAR2, doc_type IN VARCHAR2) as
f_lob bfile;
b_lob blob;
--document_name varchar2(30);
--mime_type varchar2(30);
document_name oea_documents.document_name%TYPE;
mime_type oea_documents.document_mime_type%TYPE;
dot_pos number;
v_file_type VARCHAR2(10);
begin
-- Find the position of the dot ('.') located in the filename
dot_pos := instr(filename,'.');
-- Get the filename without extension and use it as image name
document_name := substr(filename,1,dot_pos-1);
-- Build the mime type . Retrieve the file extension and add it to 'image/'
v_file_type := SUBSTR( filename, dot_pos+1, Length(Filename) );
IF ( UPPER(v_file_type) IN ('JPG','JPEG','TIF','TIFF','GIF') ) THEN
mime_type := 'image/'||substr( filename , dot_pos+1 , length(filename) );
ELSIF ( UPPER(v_file_type) = 'PDF' ) THEN
mime_type := 'application/pdf';
ELSIF ( UPPER(v_file_type) = 'DOC' )THEN
mime_type := 'application/msword';
ELSIF ( UPPER( v_file_type) = 'XLS') THEN
mime_type := 'application/ms-excel';
ELSE
mime_type := 'image/'||substr( filename , dot_pos+1 , length(filename) );
END IF;
insert into oea_documents (document_id,
document_name,
document_mime_type,
document,
document_description,
document_type
values(document_id, document_name, mime_type, empty_blob(),doc_desc,doc_type) return document into b_lob;
-- /!\ Directory name has to be UpperCase !
f_lob := bfilename('FILE_LOAD',filename);
o_dset_test('5');
dbms_lob.fileopen(f_lob,dbms_lob.file_readonly);
o_dset_test('6');
dbms_lob.loadfromfile(b_lob,f_lob,dbms_lob.getlength(f_lob) );
dbms_lob.fileclose(f_lob);
commit;
end;
FILE_LOAD is a folder on the database server(unix).
I have also tried to give the full path on the unix databse server instead of FILE_LOAD directory but then it gives error ora-22285.
while executing this procedure I am getting the error ora-22288(Invalid file or directory).
But this occurs randomly
For instance i tried to attach a pdf file with the name cross.pdf ,it gave me the above error and when i renamed the file as Cross.pdf it attached successfully.
The error comes whilke executing the statement dbms_lob.fileopen(f_lob,dbms_lob.file_readonly);
Please guide on the above issue.

FILE_LOAD is a folder on the database server(unix).
I have also tried to give the full path on the unix databse server instead of FILE_LOAD directory but then it gives error ora-22285.The first argument to BFILENAME is the name of a directory object, as found in the directory_name column of all_directories. That is not the same thing as a folder name, which is found in the directory_path column of all_directories. Look up [CREATE DIRECTORY|http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_5007.htm#sthref6211] in the SQL Language manual for a description of Oracle's directory objects.
If you have problems with this, post the results of
SELECT  *
FROM    all_directories;It might also be useful to see the Oracle "CREATE DIRECTORY" command that was used.
As you probably noticed, this site compresses white space by default.
When you post code or results on this site, type these 6 characters:
