How to set maximum available size for JApplet?

Question

I am porting my desktop Swing application to an applet. The following code works perfect for JFrame entity to set a maximum available window size, considering a task bar.

GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
Rectangle bounds = env.getMaximumWindowBounds();
frame.setMaximizedBounds(bounds);
frame.setPreferredSize(bounds.getSize());
frame.setLocation(0, 0);

In Eclipse Run Configurations -> My Applet -> Parameters I can select Width and Height or if applet is run from browser one would have to do:

<applet code="myJApplet" width="800" height="480">

But I would like to be able to set size dynamically depending on screen resolution. How would it be possible?

@StanislavL, at least in Eclipse Applet Viewer I cannot set values with % — Nikolay Kuznetsov, Jan 04 '13 at 06:36
@NikolayKuznetsov: Why wait? A [hybrid](http://stackoverflow.com/a/12449949/230513) keeps your options open. — trashgod, Jan 04 '13 at 09:51
@trashgod, thanks for links. Have to learn about hybrids. It is a pity you haven't noted about it couple of days ago [here](http://stackoverflow.com/questions/14066898/how-to-organize-code-to-build-applet-and-application-easily) — Nikolay Kuznetsov, Jan 04 '13 at 10:45
@JoopEggen, "with noscript 800x600" what does it mean, I don't understand.. — Nikolay Kuznetsov, Jan 04 '13 at 12:28
@NikolayKuznetsov: I think it means if JavaScript is blocked by a add-on in the browser, like NoScript, use hard-coded values. — Catalina Island, Jan 04 '13 at 13:18
@JoopEggen, makes sense, if you want you can post java skip solution and I would accept it. — Nikolay Kuznetsov, Jan 04 '13 at 13:58

Expanding on this previous answer, you may want to adopt a hybrid approach, which offers additional deployment options via Java Web Start. Your focus should be on developing a Container that functions well at any initial size, while avoiding common traps. Use java.util.Preferences to retain geometry that's under your control, and adapt when it's not. The details depend on the actual content, but the problem is at least well encapsulated.

Use JavaScript, with noscript 800x600. Note, this takes much memory. Though a bit troublesome, maybe better go for a Java Webstart application.

noscript is a tag <noscript>(static html content)</noscript> in which you can put conditional HTML - when JavaScript is blocked. With JS you can have a full dynamic solution, in the noscript have a fixed size solution.

oh, I have meant javascript code which would generate proper size, sorry for confusion. – Nikolay Kuznetsov Jan 04 '13 at 14:50
That I meant too. But JS can be disabled, and then a minimal functionality would be nice, hence the mention of noscript. Never mind. – Joop Eggen Jan 04 '13 at 15:11
Well, my point is that if you post complete solution of html-page with java script code then it would be definitely the best answer. – Nikolay Kuznetsov Jan 04 '13 at 15:16

I have found it here: http://andylangton.co.uk/articles/javascript/get-viewport-size-javascript/

<script type="text/javascript">
<!--
var w=window,d=document,e=d.documentElement,g=d.getElementsByTagName('body')[0],x=w.innerWidth||e.clientWidth||g.clientWidth,y=w.innerHeight||e.clientHeight||g.clientHeight;
//-->
</script>
