Here's the code: it successfully opens a terminal but nothing is displayed on the output

try { String command= "/usr/bin/xterm"; Runtime rt = Runtime.getRuntime(); Process pr = rt.exec(command); BufferedWriter os = new BufferedWriter(new OutputStreamWriter(pr.getOutputStream())); BufferedReader is = new BufferedReader(new InputStreamReader(pr.getInputStream())); String line = ""; while ((line = is.readLine()) != null) { System.out.print(line); } } catch (Exception io) { } Don't write empty catch-blocks. It's just wrong and it will cost you many hours of debugging after which you'll feel ... less than perfect. xterm produces no output by default. It just displays a window. Try starting xterm in a terminal and see which output it produces (in the original terminal, not in the new window!). Read When Runtime.exec() won't and follow all of its advice.
