open a web page from JButton?

[adiotrox]

can anyone tell me to make the following:
when the user clicks on the JButton in a frame then gmail.com page gets open? i,e. some how actionPerformed() opens the web browser with gmail.com ??

Create your button listener and give this a try.
I believe that the browser you have designated as your default browser will be used to render the webpage:

        try
          {
            Runtime.getRuntime().exec("cmd /c start http://www.gmail.com");
          } 
        catch (IOException e) 
          {
            System.out.println(e);
          }

Java applications have an instance of the Runtime class that lets you connect to the environment that your application is running inside of (which can obviously vary). So to get this runtime, you call .getRuntime() on the Runtime class.

Then, the exec method allows you to execute the string command that you pass to it. It would be the equivalent of running the command inside of a command prompt

Awesome sir, you did it in such a simplified way...thank you sir

But be sure to do this in a background thread so as not to freeze your Swing program.

Better than mucking around with Runtime, check out the API for java.awt.Desktop
