Open Browser in Java windows or Linux

A very useful Java code, to open a web browser from Java application in windows or Linux.


package com.mkyong;

public class StartBrowser {

  public static void main(String args[])
  {
	String url = "http://www.google.com";
	String os = System.getProperty("os.name").toLowerCase();
        Runtime rt = Runtime.getRuntime();
	
	try{

	    if (os.indexOf( "win" ) >= 0) {

	        // this doesn't support showing urls in the form of "page.html#nameLink" 
	        rt.exec( "rundll32 url.dll,FileProtocolHandler " + url);

	    } else if (os.indexOf( "mac" ) >= 0) {

	        rt.exec( "open " + url);

            } else if (os.indexOf( "nix") >=0 || os.indexOf( "nux") >=0) {

	        // Do a best guess on unix until we get a platform independent way
	        // Build a list of browsers to try, in this order.
	        String[] browsers = {"epiphany", "firefox", "mozilla", "konqueror",
	       			             "netscape","opera","links","lynx"};
	        	
	        // Build a command string which looks like "browser1 "url" || browser2 "url" ||..."
	        StringBuffer cmd = new StringBuffer();
	        for (int i=0; i<browsers.length; i++)
	            cmd.append( (i==0  ? "" : " || " ) + browsers[i] +" \"" + url + "\" ");
	        	
	        rt.exec(new String[] { "sh", "-c", cmd.toString() });

           } else {
                return;
           }
       }catch (Exception e){
	    return;
       }
      return;		
  
}

Of course the Desktop.getDesktop approach is much more brief, however Runtime.getRuntime().exec() has another issue – you have to consume the resulting input and error streams, otherwise you will find that resources are left open and you will eventually get errors that will appear almost unrelated, such as “too many open files”, etc.

See this link (old but still relevant) to see how….

I have a videogame (its a socail game for a lot of people to play at one time together) and when i try to run this method, as if it were a link, it only opens the link/website on my computer. Why is this?

Hi Daniel,

Do one thing.. if you know what to search, go to google, enter the word, hit search. Now copy the url its showing currently, and put in the code like

 

//String url = "http://www.google.com"; //comment this line
// I have searched for word pic, u can choose your word.
String url="http://www.google.co.in/search?hl=en-IN&source=hp&q=pic&gbv=2&oq=pic&gs_l=heirloom-hp.3..0l10.2906.3547.0.5250.3.3.0.0.0.0.234.656.2-3.3.0...0.0...1c.1.8R_O73gqzd0";

Well, but if you have a dynamic word, more expert comments is required… :)

Can be done MUCH easier: Desktop.getDesktop().browse(…) on ANY platform.
