How do i get attachment?

here is my problem:

when my program try to download attachment (i use the saveFile method from an other message in this forum)

			

			public static void saveFile(String filename,
			

			InputStream input) throws IOException {
			

			if (filename == null) {
			

			filename = File.createTempFile("xx", ".out").getName();
			

			}
			

			// Do no overwrite existing file
			

			File file = new File(filename);
			

			for (int i=0; file.exists(); i++) {
			

			file = new File(filename+i);
			

			}
			

			FileOutputStream fos = new FileOutputStream(file);
			

			BufferedOutputStream bos = new BufferedOutputStream(fos);
			

			

			BufferedInputStream bis = new BufferedInputStream(input);
			

			int aByte;
			

			while ((aByte = bis.read()) != -1) {
			

			bos.write(aByte);
			

			}
			

			bos.flush();
			

			bos.close();
			

			bis.close();
			

			}
