setOut() and redirectOutput() together (original) (raw)

Your code makes the native app inherit native stdout/err process descriptors, you need to pipe the output from your native app to Java and then redirect the output to wherever you wish (byte array for example).

In other words, Redirect.PIPE + pipe code.

I am writing something like this

ByteArrayOutputStream bout = new ByteArrayOutputStream(); System.setOut(out); System.out.println("Hello"); ProcessBuilder pb1 = new ProcessBuilder("./native-app"); pb1.redirectOutput(ProcessBuilder.Redirect.INHERIT); pb1.start(); Now "Hello" no longer shows on screen, but the output of "native-app" still shows up there. What else shall I do? This is Ubuntu 14.04.2. Thanks Max
