Get complete output from java.lang.Process

Question

How do I get the complete output from java.lang.Process?
By the time I've started reading from Process.getInputStream() the process has already terminated...

Answer 1

I solved the problem:
private int exec(String pArguments[], OutputStream pOut, OutputStream pErr) throws IOException {
     class ProcessOutputPrinter implements Runnable {
          private InputStream ivIn;
          private OutputStream ivOut;
          public ProcessOutputPrinter(InputStream pIn, OutputStream pOut) {
               ivIn = pIn;
               ivOut = pOut;
          public void run() {
               try {
                    for(int tByte; (tByte = ivIn.read()) != -1; ) {
                         ivOut.write(tByte);
                    ivOut.flush();
               catch(IOException e) {
                    e.printStackTrace();
     // Start process
     Process tProcess = Runtime.getRuntime().exec(pArguments);
     // Create out printer
     Thread tOutPrinter = new Thread(new ProcessOutputPrinter(tProcess.getInputStream(), pOut), "NamingAdmin out-printer");
     tOutPrinter.start();
     // Create err printer
     Thread tErrPrinter = new Thread(new ProcessOutputPrinter(tProcess.getErrorStream(), pErr), "NamingAdmin err-printer");
     tErrPrinter.start();
     // Wait for process and printers to finish
     try {
          tProcess.waitFor();
          tOutPrinter.join();
          tErrPrinter.join();
     catch(InterruptedException e) {
     // return process exit value
     return tProcess.exitValue();
