Redirecting System.err on two output

Hi All!

I need to redirect System.err on two output, in order to keep track of exception both on a file and on console

at this moment, I only redirect errors output on a file:

Code:

---

System.setErr(out);

---

where out is a PrintStream

when an exception occours, I'd like to print a video message also

the best result would be to print the entire stack trace, but even writing "ERROR" would be fine

could anyone help me?

I think the simplest solution is to implement a 'tee' OutputStream like this:

Code:

---

public class TeeOutputStream extends OutputStream {
  private OutputStream out1;
  private OutputStream out2;

  public TeeOutputStream(OutputStream out1, OutputStream out2) {
      this.out1= out1;
      this.out2= out2;
  }

  public void write(int b) throws IOException {
      out1.write(b);
      out2.write(b);
  }
}

---

Pass two OutputStreams to its constructor and all output writen to the TeeOutputStream will be written to the two encapsulated OutputStreams.

kind regards,

Jos

it seems perfect!

thanks!!
