Problems with class CL_GUI_FRONTEND_SERVICES

[Former Member]

Hi.

I already searched for a solution in the forum, but haven't found anything yet.

I use the method to check if a directory exists and the one to list the files. The user can specify the directory on the Appl.-Server via SELECTION-SCREEN. First the code:

CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_EXIST
  EXPORTING
    DIRECTORY            = l_unixpath
  RECEIVING
    RESULT               = l_count_unixdir
  EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2
    WRONG_PARAMETER      = 3
    NOT_SUPPORTED_BY_GUI = 4
    others               = 5.

CALL METHOD CL_GUI_FRONTEND_SERVICES=>DIRECTORY_LIST_FILES
  EXPORTING
    DIRECTORY            = l_unixpath
  CHANGING
    file_table           = l_itab_unixdir
    count                = helpvar
  EXCEPTIONS
    CNTL_ERROR           = 1
    ERROR_NO_GUI         = 2
    WRONG_PARAMETER      = 3
    NOT_SUPPORTED_BY_GUI = 4
    others               = 5.

IF l_count_unixdir = 'X'.
  WRITE: / 'Directory Exists'.
  READ TABLE l_itab_unixdir INDEX 1 INTO l_unixdir.
  WRITE:/ helpvar.
  WRITE:/ l_unixdir.
  WRITE
ELSE.
  WRITE:/ 'Directory not found'.
ENDIF.

Now my problem:

l_unixpath is '/', the result is: Directory exists, but helpvar is 0, l_itab_unixdir is empty;

l_unixpath is '/usr/sap/', the result is: Directory not found <b>(but the directory exists!)</b>;

l_unixpath is 'c:/', the result is: Directory exists, helpvar is 47, l_unixdir is "Documents and Settings".

Why it's working with the Windows-Path but not with Unix? Thanks for your answers.

Becose that class is for presentation server. You can't use it with application server.

Try FM F4_DXFILENAME_TOPRECURSION, may be helps.
