How do i download a file to my Client Machine

Hello All,
I am currently working on a Java project involving Servlet, Jsp and Oracle. Currently i am using Tomcat as my servlet container.

In the project i have a requirement to download a export file to the Client's machine. Does any one have idea about how to perform the same.

This is very urgent.

server side :
set the content type of the response to whatever mimetype has the file if is normaly downloadable or force to application mimetype, read the file and write'it on the response.

client side :
open a connection to your url, get the inputstream, read from it and write the readed content as a new file.

URL url = new URL("your url here");
InputStream is = url.openStream();
FileOutputStream fos = new FileOutputStream("a file");
byte[] buffer = new byte[4096];
while(is.read(buffer, 0, buffer.length) != -1) {
fos.write(buffer);
fos.flush();
}

...add the required try&catch statements, and of course close methods for streams.

Hello Ovi,
You talk about client side scripting, but i do not need any client side scripting. Is there any way that i could do with servlets.

Thanks for your efforts.
