Unable to read the file using UTL_FILE Dir

Question

I need to read/write a file from/to the operating system through PLSQL Package. I used UTL_FILE package to do the same. In the application server the utl_file_dir(/usr/tmp in my system) is created as a softlink to database server.
oI want to run this package through the application server. However I am unable to read and write the file to the operating system.
I just wondering it is not reading/opening the file from the server. Please suggest me how to modify my code.

Hi,
How to check if it is end of file or not? I have the following function which is working fine in my win2003 server std 32bit and Oracle10g Database R2 Standard Edition one 32bit. HOwever, when I deploy to production server which is 64bit OS and database, it gives error at UTL_FILE.GET_LINE(fptr, tmp);
Any idea why it behaves like that?
     FUNCTION readFile (
          inHTML OUT CLOB,
          path IN VARCHAR2,
          htmlFile IN VARCHAR2
     ) RETURN BOOLEAN IS
     fptr utl_file.file_type;
     tmp VARCHAR2(5023);
     bufferlen BINARY_INTEGER;
     BEGIN
          fptr := UTL_FILE.FOPEN(path, htmlFile, 'r');
          DBMS_LOB.CREATETEMPORARY(inHTML, TRUE);
          DBMS_LOB.OPEN(inHTML, DBMS_LOB.LOB_READWRITE);
          LOOP
               UTL_FILE.GET_LINE(fptr, tmp);
               if tmp is not null then
                    tmp := tmp || CHR(10);
                    bufferlen := LENGTH(tmp);
                    DBMS_LOB.WRITEAPPEND(inHTML, bufferlen, tmp);
               end if;
          END LOOP;
          WHEN NO_DATA_FOUND THEN
          DBMS_LOB.CLOSE(inHTML);
               UTL_FILE.FCLOSE(fptr);
               RETURN TRUE;
          WHEN OTHERS THEN
               DBMS_LOB.CLOSE(inHTML);
               DBMS_LOB.FREETEMPORARY(inHTML);
               RETURN FALSE;
     END readFile;
