Hello all y'all,
i want to write a servlet that enables the user to download a file; i'm
using the following code to do this but i get an IllegalStateException while
executing it. Any ideas what might be wrong?
The code fragment:
public void service(..) ... {
String filename = request.getParameter("file");
FileInputStream fis = new FileInputStream(filename);
BufferedInputStream bis = new BufferedInputStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
int ch;
while ((ch = bis.read()) != -1) {
baos.write(ch);
}
byte buffer[] = baos.toByteArray();
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition", "attachment;filename=" +
filename);
ServletOutputStream out = response.getOutputStream();
out.write(buffer);
}
Thanks in advance for your ideas.
Michael Weller
