Hey
I'm trying to install the application groundwork foundation which supports an API to use with Nagios. Anyway, when I try to launch the application i get some messages relating some problems which i think are related to Jetty web server:

Does anyone know how can I deal with this? What's the problem really? Thanks in advance.
