If you want the browser to open a specific URL from an Applet, use the
showDocument() method of the AppletContext.  The output can go to a new
window, the current window, or a specific frame within the current window.

If it is an application, then (if you don't mind trying yourself to
Windows), write a C/C++ function that contains a main and accepts one
argument (the URL to open).  The Java Application would exec this executable
passing in the URL as a "command line argument".  The C/C++ app would then
perform a ShellExecute wich will automatically launch the user's default
browser (whatever it is).

Here are some Applet and C/C++ samples:

// Applet showDocument()

                // Construct the URL that should be opened.  (all of these
steps are not necessary, I just tweaked code I had already written)
                String stringURL = new String("http://www.borland.com");
                URL commandURL = new URL(stringURL);

                // Open the URL.
                AppletContext currentContext = applet.getAppletContext();
                currentContext.showDocument(commandURL, "_ "); // this open
it in a new window.


// C/C++ code for launching default browser
#include <windows.h>
#include <stdio.h>
#include <string.h>

void main (int argc, char **argv) {

 if ((argc != 2) || (*argv[1] == 0)) {
  printf ("No file passed into function.");
  exit (1);
 }

 if ((long)ShellExecute(NULL, "open", argv[1], NULL, "", SW_NORMAL) <= 32) {

  printf("Error: Unable to start program.");
  exit (1);
 }
 exit(0);
}

You would call this executable like this:

                // Execute the command.
             Runtime.getRuntime().exec(command); // where command is the
filename.exe URL_to_open

Good luck,

Kurt
