Applet getting the browser's URL

What does this method do.

I just looked it up and I don't want the URL in which the Applet is embedded, but the URLs of the other browser windows.

in this case, you can pass the real url to the applet in two ways :
1. as an applet paramter :
this is pretty hard without asp crap, so I wouldnt go for that.

2. as a part of the url of the frame you opened :
when you open the page with the applet, give it an url argument, like
www.host.com/yourpage.html?www.calling/page.html

then, using getDocumentBase, you will be able to easly extract the thing after the '?', and thats what you need.

It's not frames based, the applet lives in a new window.  But the problem is that if the person changes the URL in the parent window I need to be able to grab the current URL of the parent window.

Think of a bookmark type application.  Where a person clicks on a link a new window appears containing my applet.  Then what happens is at a later date in the applet they will click a button and the applet then gets URL from the parent window (not the one with applet on it).

I dont think you can do it with Java only.
maybe using a combination of javascript and java, maybe some inter applet comunication.
its aint gonna be simple, thats for sure.

omry's right....there really is no way to get the URL with Java by itself, but it's easy to use javascript with it.  You are allowed to call applet functions in Javascript by referring to appletName.function where appletname is the name you give the applet in the applet tag.  so, you could do something like this:


java:

public URL getURL(String s) {
URL url;    
try {
   url = new URL(s);
} catch (MalformedURLException mfe) {}

return url;
}

and then in Javascript/html you could do something like this:
<applet code="theapplet.class" name="anapplet"></applet>
<input type="button" onClick="javascript:anapplet.getURL(window.location)">


this is just an example I'm not sure exactly what you need, all that does is pass the URL of the browser to the applet when someone clicks a button.

       

How would I get the URL of another browser window, not the one with the Applet it in, in JavaScript.  So I have 2 browser windows, one that contains the applet and another that contains whatever and I want to get the URL of this second browser window.

I don't think you can achieve this directly using Java.
It may be possible for the applet to retrieve the required information using a javascript call.
Though not sure if js can do it or not.

Best bet would be to ask question in the javascript topic to see if javascript can get the url loaded in other windows.

a bit of useful info about the problem was supplied, not our fault if Java cannot do what was required.

why?
the answer to the question is that it can't be done with Java alone.

damn browser cache.
EE, is it so hard to check if an aswer was already posted and ask the poster if he is sure he wants to repost??
and where is the refresh button (in the html)?

right.
well hidden. (used to be in the question frame, at a much better spot).
thanks.

objects & omry_y- What do you suggest should be done?
I'm refunding at least half of the points due to the nature of the answer (pretty much comes down "no"). Would a split, 25 points to each, be acceptable? (A grades will be given on the splits)
If not, you have a single comment each to make a suggestion. This has been open for too long already.

Whatever you decide is fine with me.
