How to use setTimeout for Callback function in ajax DWR?

Question

Hi,
I am facing a problem of ajax request not returning back to the specified callback function. As a result my application screen gets locked waiting indefinitely.
The timeout in DWR is controlled using a setTimeout method.
Can someone plz tell me how to implement this in my javascript code so that my Callback function is invoked for sure.
below is my code snippet...
var dwrMap = new DWRMap(theMainForm);
     dwrMap['menuId'] = menuid;     
CommonService.executeAutoLogOut(dwrMap, fnPerformLogOut);
else{
     fnDoAnalyze(analyzeUrl);
function fnPerformLogOut(response){
if(response == "timedOut"){
     alert("Timed Out");
     fnAskToLogin();
else{
     alert("Not timed out");
     fnDoAnalyze(analyzeUrl);
Here CommonService.executeAutoLogOut(dwrMap, fnPerformLogOut); is sending ajax request.
and fnPerformLogOut() is the callback function.

Hi Shyam,
Have a look at this,
START-OF-SELECTION.
  gd_file = p_infile.
  CALL FUNCTION 'GUI_UPLOAD'
    EXPORTING
      filename                = gd_file
      has_field_separator     = 'X'  "file is TAB delimited
    TABLES
      data_tab                = it_record
    EXCEPTIONS
      file_open_error         = 1
      file_read_error         = 2
      no_batch                = 3
      gui_refuse_filetransfer = 4
      invalid_type            = 5
      no_authority            = 6
      unknown_error           = 7
      bad_data_format         = 8
      header_not_allowed      = 9
      separator_not_allowed   = 10
      header_too_long         = 11
      unknown_dp_error        = 12
      access_denied           = 13
      dp_out_of_memory        = 14
      disk_full               = 15
      dp_timeout              = 16
      OTHERS                  = 17.
    IF sy-subrc NE 0.
      write: 'Error ', sy-subrc, 'returned from GUI_UPLOAD FM'.
      skip.
    endif.
