Troubles with the type associations

Question

Hello forum,
The type and extension association is really delicious, it's time this happens!
I've been trying it with moderate success, here are a few experiences, I would love advice for better results:
- first the example at http://java.sun.com/javase/6/docs/technotes/guides/javaws/developersguide/syntax.html#example
is non-well-formed. It's not long to fix but annoying.
I managed to make a first "jakarta commons jelly" web-start-application associated with .jelly files. The application can be found at:
http://klein.activemath.org/jnlpDev/webstartJelly/webstartJelly.jnlp
- on the Mac (10.4 i.e. jdk 1.5), this kind of works:
- the first launch launches the main
- the SingleInstanceListener is called at every double click on a jelly file, great! but the parameters are the original parameters (the javaws command behaves correctly though with -open).
- on Windows (Windows Server 2003, jdk 1.5), the association just doesn't work, the windows-explorer tells me to search for an application (and doesn't propose me Webstarted Jelly as it should). Do I need to restart ?
Any help for these two problems would be greatly welcome.
thanks
paul

http://klein.activemath.org/jnlpDev/webstartJelly/webstartJelly.jnlp..hmmm. With 40 separate jar archives in this
application, I cannot say I am keen to try it
(at least not at this time of night, with my
connection bandwidth!).
How big is the application (all up) in bytes?
In any case, I have some examples as
well (much smaller) at..
http://www.physci.org/jws/
Most relevant are..
http://www.physci.org/jws/#fs
..which uses the FileOpenService
and claims a .zzz file extension, and..
http://www.physci.org/jws/#sis
..which deals with the SingleInstanceService
(unfortunately, I chose not to claim any
associations for the SIS example, but
you might download both build files and
copy the association from the file
service example JNLP, into the single
instance example.)
- on Windows (Windows Server 2003, jdk 1.5),
the association just doesn't work, the
windows-explorer tells me to search for
an application (and doesn't propose me
Webstarted Jelly as it should). Do I need to restart ?I have never needed to (on Win XP).
How does that PC go with my file
service example?
..also, I only just noticed this, but while
the JNLP from my example has ..
<association
    extensions="zzz"
    mime-type="text/sleepytime" />..to claim a file extenstion, the current
version of the launch file linked above -
has no <association> element defined.
