Hi, complete novice here...pardon my stupidity!
I have Ubuntu Linux 11.04, Natty Narwahl, and am trying to use a Website that runs a .jnlp file. A few weeks ago, it worked fine, but for the last couple weeks I've had this happen:
In Firefox: dialogue box - unknown error, try saving the file to disk. If I download the file and try to open with Iced Tea Java 6, nothing happens.
In Chromium: the file downloads but again will not open (it used to run automatically)
I've not tried running it in Terminal because I don't know the appropriate commands.
I have openjdk6 installed and I've not added/removed any Java plug-ins since the problem started. I did update Firefox recently, but I'm assuming that's irrelevant as the problem is also happening in Chromium.
Can anybody offer any advice? Thanks!
