applet launches a browse resistent window

[VisionSet]

I have an applet on every page of my web app that polls a servlet.
I wish to launch some flavour of popup that persists whilst the user
browses.

1/ Launching anything like a JFrame from the applet is destroyed after
a page nav. I guess that all threads that are 'owned' by the applet
are destroyed, setDaemon(false) does not work.

2/ Launch a new browser window using
http://browserlaunch2.sourceforge.net/index.shtml But this does not
allow window sizing like a jscript popup does.

3/ Use JScript and launch the JScript from the applet.

So at the moment I'm concentrating on the 3rd approach, but since I
don't want the above list to grow into even more false trails, does
anyone else have suggestions. JWS may be number 4.

Must be 1.5 and pref 1.4 compatible

Thanks,
Mike W

You want, or your users want?

JS from within the target page should be aple to resize it once
it opens (AFAIR), which should only have to occur once.

I think JWS is your best bet here, which is ironic in that
the reason I usually reject the use of JWS'd applets is that
they _cannot_ be resized.

A JWS'd applet would fit your requirement to set the size
and allow you to do everything else you need, from within
a framework that is well supported by Sun (webstart).

Its a chat window, the user will want it. I coundn't care less, but
the boss wants it too...

Yes, so I have discovered except BrowserLauncher + Mozilla = new tabs,
when resizing I want an exclusive window.

Do you know if I can call JScript from the applet?

Yes JWS is rapidly becoming likely, better learn how it works then...

...always an important consideration. ;-)

Aha. Didn't realise that, though I'm rather glad to know
that FF does not actually spawn new browser instances -
all I ever wanted from BL2 was to get a web page before
the user's eyes (web connection permitting, etc.).

In a word - no. Not unless you are talking about attaching
...RhinoScript or whatever it is/using 1.6 (which comes with it).

The applet does not actually appear in a web page, it appears
in the applet viewer - the only reason you need to specify a
home web page in the JNLP for an applet is for some of the
applet parameters (like size).

Here you can find two web-start examples of the same
(simple) program launched using JWS applet/application.

...the webstart for a app. that does not require a trusted
environment can be very simple. Trusted apps. are a
different matter (what with code signing).
