Hi Ruwan,

In Runtime, you have some exec() methods you can use for this.
The most simple one is:
Runtime.getRuntime().exec("notepad.exe");


However, if you want to run true DOS commands (copy, dir, ...), you'll have to call the shell like this:
Runtime.getRuntime().exec(%

There was an answer to this recently. You don't say what OS you are on.
On Win9x this works:
Process p = Runtime.getRuntime().exec("START xxxxx.html");

hmmm.... windows NT doesn't seem to support the "START xxxx.html" command, even if it does work from DOS command prompt.

what i managed to find is this shortcut command that could work from the Runtime method:
"rundll32 url.dll,FileProtocolHandler xxxxx.html"
which works fine with my WinNT terminal.

this is the link where i found this tip:

Try this:

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.net.*;
public class Browser extends Applet
implements ActionListener
{
public void init()
{
Button b = new Button("go");
b.addActionListener(this);
add(b);
}
public void actionPerformed(ActionEvent ae)
{
try
{
getAppletContext().showDocument(new
URL("http://www.javasoft.com"), "_blank");
}
catch(Exception e)
{
System.out.println("" + e);
}
}
}
