Here is a simple example of opening IE in swing application.

class OpenBrowser 
{
    public static void main(String[] args) 
    {
          String browserPath = "C:/Program Files/Internet Explorer/IEXPLORE.EXE"; 
          String url = "www.roseindia.net";
          try {
               String[] b = {browserPath, url};
               Runtime.getRuntime().exec(b);
           }
           catch (Exception exc) {
        exc.printStackTrace();
           }
    }
}
