getting odd situation here: the game works on other computers, but
mine is stuck with this error message:

I’m trying to clear browser caches, Java caches, this happens both in Firefox and Google Chrome so it shouldn’t be the browser.
Java cache shows as being emptied but i am getting suspicious. Tried a clean boot, no help.
What’s up I wonder, wasted the whole day banging my head on this one…
Also exactly the same program, with different paths in the html and jnlp file work just fine on another server.
It’s a big wtf…
[EDIT] fragme, it’s now on both my home computer and work computer, but still works on others… what on earth have i done wrong?
here’s the jnlp file…

Try including a codebase attribute.

#3

added

still no dice… I don’t quite understand where to look for the problem - everything was fine and working, i made no changes, suddenly pox,
about after the Java Update… thinking of checking that as well, downloading the previous update. [EDIT] tried that, no dice. This is so frustrating, one of those things I know I could just work around with the backup server but it’s killing me not to see it on the live one… The other developers don’t report any problem. grey hairs

Made a test, just moved the whole shebang up one folder, tested again, works. Only change is removed the dev/ from the html and jnlp files. What the spoo?
since this happened to the main page also,it doesn’t solve the problem…

#4

Some weird caching issue? If you clear your webstart cache locally does that help?

#5

add a trailing slash !

<jnlp codebase="http://ottawa.vps.kotisivut.com/dev/applet/"
	 href="slicks.jnlp">

I got the message : Authorization Required with firefox.

#6

Added trailing slash, no difference.

I think Java cache is the problem, but ControlPanel->Java->Temporary Internet Files->Settings->DeleteFiles does not help,
and the View is empty after doing it. However, if I check the contents of the cache folder there is a lot of junk there.
Is it safe to wipe it all?

this version ( no authorization password ) http://test.digitalfootmark.com/slicks/applet/test.html
works fine, and is to all purposes identical, except it is testing the undecorated mode which is still buggy.

http://ottawa.vps.kotisivut.com/dev/applet/test.html works for everybody else, but mine is stuck.
Since we are almost due to release I will now reveal the password, and change it next week.
It is only read access password, not full access, so no security stress issue.
