Question

For a web application built on struts and jsp technologies, I'm looking for a good example which explains how to download files from the server side.

Answer 1

i manage to do it with this few lines of code : just add this to your action :

OutputStream out = response.getOutputStream();
        response.setContentType("application/rtf");
        FileInputStream in = new FileInputStream("your_file_path");
        byte[] buffer = new byte[4096];
        int length;
        while ((length = in.read(buffer)) > 0){
            out.write(buffer, 0, length);
        }
        in.close();
        out.flush();
