Java HotSpot Virtual Machine

Hello,

My Java application runs native code written in c++.
I need to display some messages from c++ std:cout into a JTextPane.

First, I tried to display the standard PrintStream output "System.out" but it only shows Java messages. Here is my code:

import java.awt.Color;
import java.io.OutputStream;
import java.io.PrintStream;

import javax.swing.JTextPane;

public class LogTextPane extends JTextPane {
	private static final long serialVersionUID = 1L;
	private MyPrintStream mps;
	protected LogTextPane(){
		super();
		this.setBackground(new Color(1,1,0.8f));
		mps = new MyPrintStream(System.out);
		System.setOut(mps);
	}
	class MyPrintStream extends PrintStream {
	    MyPrintStream(OutputStream out){
	    	super(out);
	    }
	
	    public void println(String string){
	        setText(getText() + string + "\n");
	    }
	    
	    public void print(String string) {
	        setText(getText() + string);
	    }
	}	
}

Anyone has an idea? Thanks in advance
Best
