Possible. What's interesting is that the shortcut created for JADE contains the following command line:
Code:
C:\Windows\System32\javaws.exe -localfile -offline "[%userprofile%]\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\9\45bc4d49-2c33fa39"
(for [%userprofile] substitute the actual value of that environment variable).
So if the -offline parameter does what it seems like it ought to do, or at least what I'd guess it was intended to do, the program ought to work offline.
When I run Web Start manually, without any parameters, it puts up a "usage" dialog showing various options. One of the other possible parameters is -Xnosplash, which claims to "run without showing a splash screen". I assume this means "no Web Start splash", not "no JADE splash". I wonder if it would be worthwhile to add this parameter to the command line.
I'll play around with some of this stuff later when I'm offline, just to see what happens.
For what it's worth, my PC is running Vista SP2 (32-bit), and I have Java(TM) Web Start 1.6.0_25 installed.
UPDATE: OK, now I'm baffled: This error seems to occur on my PC completely at random. I've had it appear or not appear whether or not I am online. I have not yet been able to isolate a definite trigger, but internet connectivity (or lack thereof) does not appear to be the cause after all.
