I have an application that uses tomcat 5.0.19. At one point in my
application, the user has the possibility to click on a certain link in
order to download a file.
Once the file is downloaded, I would like the application to go to a certain
jsp page.... is there a way to configure tomcat to do such a thing? I mean,
to redirect to a page only if the download has been successfully ended?
Maybe this can work:
Write a a servlet (or JSP) that delivers the file to your user, e.g.
response.setContentType("application/octet-stream"); //or whatever
java.io.InputStream data =
new java.io.FileInputStream("file.bin");
byte[] buf = new byte[4 * 1024];
int len;
while ((len = data.read(buf, 0, buf.length)) != -1) {
sout.write(buf, 0, len);
}
After that you can forward to the desired page:
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher("fwd.jsp");
dispatcher.forward(request, response);
