Check out:

http://forum.java.sun.com/thread.jspa?threadID=148084&me ssageID=420078

The gist of it is that you can tell System to redirect System.out to an
alterate PrintStream. You should be able to create your own PrintStream
that does whatever you want, including printing output to an SWT Text
widget.

the problem is that I've redirected System.out to a new PrintStream but I

Try something like this:

import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintStream;

import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.*;

public class ConsumeSysout {

public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
final Text text = new Text(shell, SWT.NONE);
shell.open();

OutputStream out = new OutputStream() {
@Override
public void write(int b) throws IOException {
text.append(Character.toString((char) b));
}
};
System.setOut(new PrintStream(out));

System.out.println("Hello World!");

while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}
