I have never heard of it. I am researching on how to implement the internet to my program and I come across it. it seems to be easier then what I was trying to do for the past while. Could someone please link me to a website that can provide a simple to understand, but in depth enough that I could understand the concept. Also some random bits of code to help me understand would be appreciated (if you wouldn't mind).

Do you have any other ways, that are relatively easy, to implement internet into my program? in web browser like format.


Then is there a way to implement a website like page like notch did in his new minecraft launcher?


Here is a Browser and some links to examples. Maybe you can send it a address when you need it good luck.

package view.utils;
/* Examples:
 *     Browser.displayURL("http://www.javaworld.com")
 *     Browser.displayURL("file://c:\\docs\\index.html")
 *     BrowserContorl.displayURL("file:///user/joe/index.html");
 * Note - you must include the url type -- either "http://" or "file://".

due all my respect to your person, that isn't about your knowledge, about your excelent level that came form your answer .. or not about that you hold this forum in your hands, about that just my hat down to your great person


don't spoke about dead stinky fish that isn't dead or stinky, just paused or not definitelly dead

then lots of Greats and Richiest another projects from Java.net.... and long time not definitelly dead too, just we can tell long time INACTIVE, PAUSED, that really not dead, SwingX 2y Inactive (inspirated into Java7), Substance 1y closed by Kirill decision (transmitted to someone http://www.springone2gx.com/blog/danno_ferrin/2011/04/insubstantial_6_2_release),.... etc (I tried these two long time), yes Nimbus survived to thess days

back to the Desktop API

I can't anything as == yes you have right it isn't definitelly dead, well like as another Desktop API's child JMF, some API without any start and end to, just inactive since year 2006 nothing else just PAUSED and INACTIVE


Hi mKorbel. Thanks for the kind words! But please don't think I hold anything "in my hands". I'm just a contributor with a bit more spare time than many others.

Anyway, Desktop... I think we may be talking about different things - there's an old Desktop project that, as you say, is inactive. The Desktop API in Java 6 is definitely mainstream fully-supported code, just like the rest of the API.
I agree about JMF's sorry state, but I don't think that's connected in any way to the Java 6 Desktop API.


Sorry mKorbel I guess JamesCerrill upset you too.
I'm here to share code ;)

I did look at a new browser code and I dumped it in the code I gave

I simply sent in the url and it works beautiful: just use this method

or make it a class.

public static void onLaunchBrowser(String url) throws URISyntaxException {  
       if (Desktop.isDesktopSupported()) {
            desktop = Desktop.getDesktop();
            // now enable buttons for actions that are supported.
        URI uri = null;
        try {
            uri = new URI(url);
        catch(IOException ioe) {
        catch(URISyntaxException use) {

good luck.


Sorry ceyesuma, I certainly didn't intend to upset you! I realised that it wasn't your own code I was criticising, but I assumed you were also unaware that it was very old and used an approach that had been replaced by something much better.
Once again, if I caused offence, I apologise.

ps: Your latest code is great.


@ ceyesuma

:-) +1, this about real usage of, not about possibilities

<:-)> and then tell us how you can use myStle.css correctly (more than 500lines CustomWoodoo about definitions for create Stylled Document from SomeJavaGuru) and with todays Html syntax (Html ver.> 3.2), yes there are exist 3.rd part API </:-)>

We live and learn. Thanks for the heads up for some better code.
