How do you want to open that URL? In your preferred browser? In a custom control?

[Nina Milo]

Yes its possible.
Get the runtime instance of the application and then execute the command.All this should be implemented within the actionlistener. Hope this is helpful.

sample action listener code:
******************************************
JButton button1= new JButton("Button1");
button1.addActionListener(new ActionListener(){

public void actionPerformed(ActionEvent e) {

try{

String command = "C:\\Program Files\\Internet Explorer\\IEXPLORE.EXE http://java.sun.com/" ;

Process link = Runtime.getRuntime().exec(command);
}
catch(Exception ex){
System.out.println("cannot execute command. " +ex);
}
}
});

Nina, that is a very platform specific solution. We need to wait on answers to Rob's questions before giving the best solution.

I did some googling and found this tidbit:

package util;
 
/**
 * Bare Bones Browser Launch
 * Version 1.5 (December 10, 2005)
 * By Dem Pilafian
 * Supports: Mac OS X, GNU/Linux, Unix, Windows XP
 * Example Usage:
 *  String url = "http://www.centerkey.com/";
 *  BareBonesBrowserLaunch.openURL(url);
 * Public Domain Software -- Free to Use as You Like
 */
 
import java.lang.reflect.Method;
import javax.swing.JOptionPane;
 
public class BrowserLauncher {
 
private static final String errMsg = "Error attempting to launch web browser";
 
public static void openURL(String url) {
String osName = System.getProperty("os.name");
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 = {
"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, errMsg + ":\n" + e.getLocalizedMessage());
}
}
}

Be aware that this works only on an English-language Windows version. The BrowserLauncher class not only works on Windows versions in other languages, but also on other operating systems. Given how easy it would be to use that, I wouldn't consider what was posted above to be a proper solution.
