I don't see a reply to this, but found it because I was searching on a similar issue. I have two machines, one running PCLOS Gnome and this new one running KDE. Both up-to-date, both running PAE kernels. On the Gnome machine I can double-click the .jar (RemoteDroidServer.jar, for what it'sworth) and it opens right up. Here on KDE it is opening in Ark, and I don't see a method of having it launch.
