Hot on the trail of JNLP failure

Thread view:

Roedy Green - 25 Mar 2008 19:10 GMT

On my machine, any desktop icon to launch Java Webs Start app fails
with a message about Java not being installed.

I discovered manually created shortcuts to the JNLP file would work.

I discovered today that modifying the shortcut to use C:\Program
Files\Java\jre1.6.0_05\bin\javaws.exe instead of
C:\windows\system32\javaws.exe also works.

Oddly, the javaws.exe in both directories is identical. I take this
to mean there is something that is screwing up the way javaws.exe
finds the currently installed JRE.

I have reinstalled Java, no joy.

Can you give us the URL to any one JNLP
that has been
a) validated &
b) seen to fail since last validation.

If you go to http://mindprod.com/webstart/setclock.html

You can run the app fine in the browser. Yet I can't use the shortcut
created. The JNLP file is the same in both cases.

I can also run the app by creating an app that points directly to the
JNLP file (not using javaws to create the shortcut).

404 but..

..note that I did not ask for the applet URL,
but the URL of the JNLP.

Further, using this Dell Latitude 300MHz
computer on a connection that screams
along at around 2-3KPS, I am not in a
position to go hunting through a bunch of
applet based pages, looking for a link to
a JNLP.

Provide a link (direct) to the JNLP and
I can investigate further.

One thing I can ask 'off the top of my head'
is .. Does the launch file specify an HREF
attribute in the JNLP element?

Please don't jerk me around. You know perfectly well how to get the
JNLP file.
