Problem while downloading file from custom table

Question

Hi All,
Im trying to download the file from the custom table where i have stored the uploaded files through apex.
I have created the download procedure as mentioned in the oracle docs ,
And given the execute grant for public user.
and calling that procedure by calling the URL -- #OWNER#.download_my_file?p_file=#ID#
But im getting the below error
Forbidden
You don't have permission to access /pls/apex/owner.download_my_file on this server.
Oracle-Application-Server-10g/10.1.2.0.2 Oracle-HTTP-Server Server at servername Port number
Can any one tell whats the problem here.
Thanks in advance
regards,

Your function apex_util.get_blob_file_src under region, the first argument must be the name of page item anywhere in your application that is of type "file browse." So if your form for uploading the blob content is on page 11 and the file browse item is "P11_FILE_NAME" then your query would look like below:
SELECT FILE_ID
     , FILE_NAME
      , CASE WHEN NVL(dbms_lob.getlength(BLOB_CONTENT),0) = 0
       THEN NULL
        ELSE
              CASE WHEN attach_mimetype like 'image%'
            THEN '<img src="'||apex_util.get_blob_file_src('P11_FILE_NAME',id)||'" />'
            ELSE
                 '<a href="'||apex_util.get_blob_file_src('P11_FILE_NAME',id)||'">Download</a>'
           end
       END new_img
    FROM TABLE_NAME
GET_BLOB_FILE_SRC FunctionAs an alternative to using the built-in methods of providing a download link, you can use the APEX_UTIL.GET_BLOB_FILE_SRC function. One advantage of this approach, is the ability to more specifically format the display of the image (with height and width tags). Please note that this approach is only valid if called from a valid Oracle Application Express session. Also, this method requires that the parameters that describe the BLOB to be listed as the format of a valid item within the application. That item is then referenced by the function.>
