я делаю так:
| Код |
FacesContext fc = FacesContext.getCurrentInstance();
HttpServletResponse rs = (HttpServletResponse) fc.getExternalContext().getResponse();
ServletOutputStream sos = null;
rs.setHeader("Content-Disposition", "attachment;filename=\"katch.xls\"");
try {
FileInputStream fis = new FileInputStream("katch.xls");
File fi = new File("katch.xls");
byte[] b = new byte[(int) fi.length()];
fis.read(b);
sos = rs.getOutputStream();
sos.write(b);
sos.close();
} catch (IOException ex) {
ex.printStackTrace();
}
fc.responseComplete();
