Hi!
Please help!
I have Problem in setting the MIME Type in JSF.
I Implemented a method called "createXReport" that create report using JXL
and output it on the outputStream directly.
that result in a dialog asking the user either to save or to open this
report which is an excel report but this dialogue when return it say that it
is an HTML page not Excel.
and there exist a JSF page with commandButton that when clicked call this
method  but what happens is that the returned streamData
didn't have the content type I set it in my createXReport.

and this is the JSF page code's  "ReportsScreen.jsp"

<h:commandButton id="GenerateXReport" value="create XReport" title="Generate
X report" action = "#{reports.generateXReport}"/>

and this is the Method Code

public void generateSalaryReport() {
  FacesContext faces = FacesContext.getCurrentInstance();
  HttpServletResponse response =
(HttpServletResponse)faces.getExternalContext().getResponse();

 OutputStream out = null;
  try{
          response.setHeader("Content-Disposition", "attachment; filename=
XReport.xls");
          response.setContentType("application/vnd.ms-excel");

          WritableWorkbook w = Workbook.createWorkbook(
response.getOutputStream());
          WritableSheet s = w.createSheet("XReport", 0);

            // writing the headers columns.
            s.addCell(new Label(0, 0, "Date"));

.....................................................................................
            List X = _reportingService.getXReport();
            Iterator it = X.iterator();

......................................................................................

            w.write();
            w.close();

        } catch (Exception e)
        {
            _logger.error("Exception in Excel Sample Servlet\n" + e.getCause
());
        }
}

thanx in advance
