RE: Downloading a file from an Action class.

[Wang, Yuanbo]

ByteArrayOutputStream baos = new ByteArrayOutputStream();
PrintStream ps = new PrintStream(baos);
ps.print(new String(returnStr));
ServletOutputStream sos = response.getOutputStream();
baos.writeTo(sos);
sos.flush();
sos.close();

Then return null ActionForward in your action method. 

Thanks,
Yuanbo

        Hi!

        I try to download a file from an action class to the user PC.
That's what I do in the action class:

                String Path                     = "C:" +
java.io.File.separator;         //Location of the file
                String FileName                         =  Path +
"CSV.TXT";                              //Name of the file
                int buffer                              = 10 * 1024;
                File file                               = new
File(FileName);
                FileOutputStream fos            = new
FileOutputStream(file);

                //Fill the file with some information.
                PrintWriter pw = new PrintWriter(fos);
                for (int i = 0; i< 200; i++) {
                        pw.write("l1 campo1" + ";" + "l1 campo2" + ";" +
"l1 campo3" + "\n");
                        pw.write("l2 campo1" + ";" + "l2 campo2" + ";" +
"l2 campo3" + "\n");
                }

                pw.flush();
                pw.close();

                fos.close();

                //download
                response.reset();
                response.setContentType("text/plain");
                response.setHeader("Content-Disposition", "attachment;
filename=\"" +
file.getName() + "\"");
                response.flushBuffer();

                return null;

        All works fine, but when the user save the file, it's empty. Any
ideas..

Thanks in advance.
