Using headless linux host to run jruby script on VNC screen

Asked by Jivan Kulkarni

Provided that the SikuliX setup jar requires a screen, what is the best way to setup a headless client that will VNC into other machines?
I plan to use the JRuby gem from GitHub which works fine on a windows machine that has the SikuliX IDE installed with the sikulixapi.jar. I copied the jar and set the sikulixapi_jar environment variable and get the following error:

[error] ResourceLoader: checkLibsDir: Not a valid libs dir for SikuliX (amd64): /root/libs
[error] ResourceLoader: checkLibsDir: Not a valid libs dir for SikuliX (amd64): /root/libs
NameError: missing class or uppercase package name (`org.sikuli.script.Screen'), caused by (NameError) cannot initialize Java class org.sikuli.script.Screen

I don't have sure if I understood what you want to do. But if you want to run something that needs a screen without having a screen, have you tried xvfb? http://en.wikipedia.org/wiki/Xvfb

Can you help with this problem?
