Internet explorer not saving excel files

[mcadirci]

Hello,

First of all I am new to spring, if I have searched for solution at web but can not figure out the solution.

I have a controller which reads requests, generates excel file and writes it via HttpServletRequest's outputStream.

Firefox and Chrome tries to save the xls file. But internet explorer 9 tries to view the content of the file. Some ideas would be great.

@RequestMapping("/excel/*.xls")
    public ModelAndView handleRequest(HttpServletRequest argRequest, HttpServletResponse argResponse) throws Exception
    {
        this.initFonts();
        Map<String, String> requestParams = ReportUtilFactory.getInstance().getCsvReader().readParameterMapFromRequest(argRequest);
        this.reportData = ReportUtilFactory.getInstance().getReportDataReader().getReportdata(requestParams);
        OutputStream outputStream = argResponse.getOutputStream();
        WorkbookSettings wbSettings = new WorkbookSettings();
        wbSettings.setLocale(new Locale("tr", "TR"));
        WritableWorkbook workbook = Workbook.createWorkbook(outputStream, wbSettings);
        workbook.createSheet("Report", 0);
        WritableSheet excelSheet = workbook.getSheet(0);
        this.addCommonInfo(excelSheet, this.reportData);
        this.setColumnWidths(excelSheet, this.reportData);
        this.addHeaders(excelSheet, this.reportData);
        this.addRows(excelSheet, this.reportData);
        workbook.write();
        workbook.close();
        argResponse.setContentType("application/x-msexcel");
        argResponse.setHeader("Content-Disposition", "attachment; filename=sheet.xls");
        return null;
    } 

+This is a screen shot if I am not clear:
