Visit url in webbrowser from a link from my application

Question

Hello,
I have a java application. I would like to send my users to a specific URL for example "www.google.com". How do I do that?
I've got this great answere:
import java.lang.reflect.Method;
import javax.swing.JOptionPane;
public class test {
    public test() {
     public static void main(String[] args) {
      String osName = System.getProperty("os.name");
      String url = "http://www.google.com/";
      try {
         if (osName.startsWith("Mac OS")) {
            Class fileMgr = Class.forName("com.apple.eio.FileManager");
            Method openURL = fileMgr.getDeclaredMethod("openURL",
               new Class[] {String.class});
            openURL.invoke(null, new Object[] {url});
         else if (osName.startsWith("Windows"))
            Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url);
         else { //assume Unix or Linux
            String[] browsers = {
               "gnome-open", "firefox", "opera", "konqueror", "epiphany", "mozilla", "netscape" };
            String browser = null;
            for (int count = 0; count < browsers.length && browser == null; count++)
               if (Runtime.getRuntime().exec(
                     new String[] {"which", browsers[count]}).waitFor() == 0)
                  browser = browsers[count];
            if (browser == null)
               throw new Exception("Could not find web browser");
            else
               Runtime.getRuntime().exec(new String[] {browser, url});
      catch (Exception e) {
         JOptionPane.showMessageDialog(null, e.getLocalizedMessage());
The problem
But do you know how I can make it open in the current open webpage after the first time? So its like refreshing the website.
Because now it opens a new tab for every time and I will end up with hundreds of thoose.

The code you have in front of you is browser independent. The solution you're asking for is browser-dependent. If you're using firefox, you're going to have to tweak the solution you've got in front of you to use that specific browser.
For firefox (and most other browsers), there are switches (-t?), depending on what version you use, that will allow you to open the link in a new tab. Presumably, there are switches that will tell it to also use the current window. However, I don't know what OS or browser you're talking about.
