Código PHP:
public ActionForward exportExcel(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
UserForm userForm = (UserForm) form;
ExcelCreator excelCreator = new ExcelCreator();
HSSFWorkbook workbook = excelCreator.createWorkbook(userForm.getUserList());
response.setHeader("Content-Disposition", "attachment; filename=UserDetails.xls");
ServletOutputStream out = response.getOutputStream();
workbook.write(out);
out.flush();
out.close();
Si existe alguna forma??.
Gracias y saludos.
