Getting java gui to open a webpage in web browser

I am trying to get a java gui to open a web page. So the gui runs some code that does things and then produces a html file. I then want this file to open in a web browser (preferrably Firefox) as soon as it is created. How would I go about doing that?

If you're using Java 6 or above, see the Desktop API, in particular browse. Use it like this (not tested):

// using this in real life, you'd probably want to check that the desktop
// methods are supported using isDesktopSupported()...

String htmlFilePath = "path/to/html/file.html"; // path to your new file
File htmlFile = new File(htmlFilePath);

// open the default web browser for the HTML page
Desktop.getDesktop().browse(htmlFile.toURI());

// if a web browser is the default HTML handler, this might work too
Desktop.getDesktop().open(htmlFile);

Ya, But if you want to open the webpage in your default web browser by a java program then you can try using this code.

/// file OpenPageInDefaultBrowser.java
public class OpenPageInDefaultBrowser {
   public static void main(String[] args) {
       try {
         //Set your page url in this string. For eg, I m using URL for Google Search engine
         String url = "http://www.google.com";
         java.awt.Desktop.getDesktop().browse(java.net.URI.create(url));
       }
       catch (java.io.IOException e) {
           System.out.println(e.getMessage());
       }
   }
}
/// End of file
