it forwarded me to page with "unreadable data"
comapred to the first example, you omit the
resp.setHeader("Content-Disposition", ...
here is the code ,i have the export method in a dispatch action :
public ActionForward exportSelectedIntaff(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response) {
and i put this, after the creation of the excel file
try {
OutputStream out = response.getOutputStream();
FileInputStream fileStream = new
FileInputStream(filePath.replaceAll("/", "//"));
int bufferLen = 1024 * 8; // 8 KB
byte[] buffer = new byte[bufferLen];
while (true) {
int max = buffer.length;
int len = fileStream.read(buffer, 0, max);
if (len > 0)
out.write(buffer, 0, len);
else
break;
}
} catch (IOException e) {
// TODO: handle exception
}
