redirecting stdout 1

[mixer]

When running an application in a Windows environment (java -c pathstuff apps.MyMain), is there an option to redirect stdout to a text file and not the dos window?

Thanks.

Place > followed by the fileName after the java filename, for Example:

java -c pathstuff apps.MyMain > redirectStdOutToTextFile..txt

Thanks. I thought this would work also. When I run it locally, it works. When I run it on the network, it creates the file, but does not put any of the Sys.out.println() stuff in it. May have something to do with the network config here. Thanks again.

Is there a way to get output from Exceptions redirected as well?

I don't know whether you can redirect stderr to a file (via the commandline, without changing your code).
What you can do is use a method like the following :

  /**
   * Method redirect stdout and stderr to specified directory.
   */
  public static void redirect(File directory) {
    try {
      File tempFile = File.createTempFile("stderr", "", directory);
      System.setErr(new PrintStream(new FileOutputStream(tempFile)));
      tempFile = File.createTempFile("stdout","", directory);
      System.setOut(new PrintStream(new FileOutputStream(tempFile)));
        }
      catch (Throwable t) {
        System.err.println(
          "Error overriding standard output to file.");
        t.printStackTrace(System.err);
      }
    }

You can call this method like (ps : the directory must exist) :

    redirect(new File("D:\\java\\Temp"));

Thanks. I was so focused on the command line I never thought about redirecting System methods in the code. This will work fine.
