#35 Exception in thread "main" java.lang.NoClassDefFoundError: edu/uci/ics/jung/graph/MultiGraph

Hi, I installed jnetmap on my Xubuntu VM. I also installed Java 8 and JDK 8, but when trying to execute jnetmap no window appears. Executing jnemap from terminal a list of errors comes down.

I tried everything, but I'm not so confident with Linux. May someone could help me?

Thanks a lot

Hi M

Have you tried the development snapshots over at http://www.rakudave.ch/jnetmap/?file=download ?
(the current release is getting a bit long in the tooth and has thus become a bit picky about the exact version of Java you use)

cheers

Hi rakudave,

I forgot to update you that I tried the 0.5.5 release and it works well!!

I'm exploring various features, it's running good, except for plugins. I can download, select them, but when suggested to reload the app, I cannot find any new plugin in the list.

Have a nice day
M

[rakudave]

that's good to hear :-)

yeah, I've ripped out the entire plugin system and replaced it with a new one - you can find matching .jars on the same page you got the dev builds from. Plus some of them (such as SSH, VNC etc.) have been superseded by the "scripts" feature, which simply calls other native tools instead of shipping half-baked Java clones ^^

cheers

I'm receiving the same error and would love to try the new version referenced above but can't figure out where to download it. Any help would be greatly appreciated!

Hmpf, the trailing question mark seems to have messed up the link above (fixed) - simply head over to http://www.rakudave.ch/jnetmap/?file=download and select "Development Snapshots"
