Howdy,
A servlet container is required to supply your application with a
directory where you can run temporary files. This directory is
available via
File tempDir = (File)
getServletContext().getAttribute("javax.servlet.context.tempdir");
You'd know the above if you'd read the servlet specification, but I'm
getting tired of that mantra ;)
Then you can say:
File myTempFile = File.createTempFile("prefix.", ".suffix", tempDir);
// Use a FileWriter or whatever to write your file
// Stream or link this temp file's contents back to the browser
// Stream via FileReader,
// or directly link file File.toURI().toURL(), or whatever method you
want
You can then delete the file if you want.
