[jboss-user] [JBoss Portal] - file download

[brain101]

is it possible to realize a file download via a portlet?
via servlet the code would look something like this:
		response.setContentType ("text/plain");
		response.setHeader ("Content-Disposition", "attachment; filename=\"testfile.txt\"");
		ServletOutputStream op = response.getOutputStream ();
		InputStream in = new FileInputStream(p_dir+request.getParameter("p_file"));
		byte[] b = new byte[4 * 1024];
		int len = 0;
		while ((len = in.read(b)) != -1) {
			op.write(b, 0, len);
		}
		in.close();
		op.flush();
		op.close();
