JAWS failure

This just started happening.

I can run a JAWS app from within the browser.
But when I later go to run from the desktop icon it says I don't have
Java 1.6 installed.

Here is a typical JNLP file after JAWS has normalised it:

<jnlp spec="1.6+" codebase="http://mindprod.com/replicator/"

I tried reinstalling Java . No joy. I can run JAWS apps from a
browser, but not from the desktop icon.

I have improved things a bit by uninstalling the JDK and wiping clean
the directories, registry, stuff all stuff in the control panel and
the desktop icons and C:\users and reinstalling.

Now JAWS apps will start within the javaws -viewer. They will launch
from a JNLP on the desktop, but the won't launch from the icons JAWS
creates on the desktop. It still complains Java 1.6+ is not
installed.

Could you have a JVM from a different vendor that is a bully?

Check the executable the desktop icon links to, then paste that (full
path) into a commandline with -version. That should give some clue,
hopefully.

Also, try rebooting in between de- and re-installs, if you haven't.

just Sun, just JDK 1.6.0_04.

The desktop links invoke javaws.exe with a cache entry. That is
definitely a place to dig.

I think I rebooted, but just in case I will try again. thank you. I
have been baffled by this one, since it USED to work, and I can't
think of anything I changed that would be relevant.

no joy. same behaviour. Presumably the trouble
must be somewhere in windows.
Yeah, it's a major peeve I have with MS Windows systems, no two
installations of the same OS behave the same!

Your problem really is a doozie. Do the java executables work in a
command line? Double check the environment settings.

Other things you can try is a checkdisk and defrag.

I can launch the JAWS apps fine in several ways:
- in a browser
- with an JNLP icon shortcut
- within Javaws.exe

Just not via the shortcuts javaws creates on the desktop that point
into the cache.

It somehow thinks Java is not installed.

I can't figure out what possibly could be different before and after.
It USED to work. The only thing I can think of is some Vista update.
