Java web start won't start!

Hello,

I'm on Ubuntu Linux, and I did a JWS instalation. It has worked on the past.

Now, when I try to run javaws, I got the error:

Java Web Start splash screen process exiting .....

Splash: sysCreateListenerSocket failed: file or directory not found

Does anyone have this problem already? More important, does anyone could solve it? I googled for it and found just 16 pages, none with an answare!

Thanks!

Hi,it can be problem with firewall, so try to grant acess to the Internet to javaws.exe or try to shut it down for a momentL.P.

I've had the same issue here (Linux, Sun Java 5). Glancing briefly over the output of strace, I've found out that my loopback interface wasn't up. Upped it and the problem was solved.
