Buy an Axon, Axon II, or Axon Mote and build a great robot, while helping to support SoR.

No, we do not block java apps on the pc's. What does crop up is running incompatibility between the latest releases of java and what must be supported by IMPS. Try reinstalling the JRE and checking that your jnlp is compatible with your current setup.

It seems to be somehow related to the bandwidth and to the size of the jar. I never get this error when I launch the application from the local network, it only happens when "the line" is slow.Another suspicious thing is the message in JNLP downloading dialog: "Download stalled", but with the combination of luck and patience (waitng ~60 sec) the application starts normally.
Is your work connection slow?
Could you send me a special offline file for now, until I get this worked out?
Also, I noticed it doesn't work in offline mode - how can I get that to work? This is very important when programming at robot competitions without internet access . . .
The NRL is a military-run operation, top heavy with bureaucracy, draconian generals, 'it's good enough for government work' employees, and I'm just a wee little civilian researcher in a basement lab with a robot fish. Even if I could get them to do it, it'll take weeks or months.On the bright side, madsci says they ban GPS and USB keys on his base down in Florida, so I guess I can't complain . . .
QuoteAlso, I noticed it doesn't work in offline mode - how can I get that to work? This is very important when programming at robot competitions without internet access . . .Well it 100% definitely does work offline. Its just that we cleared your cache when trying to get to the bottom of your problem. So you now have no versions of Project Designer installed on your machine and you cant download a new version due to your firewall. So you are now 100% Project Designer free.

Forget all that jiggery pokery. Just unplug your network cable or wifi card and click on the desktop shortcut icon for Project Designer.So long as the app is still in your browser download cache (and hasn't been kicked out cause your cache has exceeded the limit set by Windows) it will run the last version you downloaded if it cant connect to the net. If not then log a bug at the Sun/Oracle support site - as that is the whole concept of what Java Web Start does and is 100% out of my control ie there is NONE of my code that is even executed until AFTER a downloaded/cached version of the program is run.

Well it 100% definitely does work offline.
all those Windoze options like clearing up 'temporary files' also tend to wipe out the cache.

I would be happy to help resolve the problem, I still need to know the port number for the jar file. I was able to glean the url from the error message but the rest is still a mystery.
On a side note, the tech here just sent me this email a minute ago:QuoteI would be happy to help resolve the problem, I still need to know the port number for the jar file. I was able to glean the url from the error message but the rest is still a mystery.I'd assume the port is dynamically chosen by the Java software and that you have no control over it, but just wanted to verify this first . . . I googled around, but wasn't exactly sure what terminology I was searching for to find out myself . . .
