[arch-general] access jnlp file with icedtea-web

Hello, i'd like to access a jnlp file with icedtea-web on my arch system. I need this for locale access via ipmi to my server system at home. When i start the file with icedtea-web on a terminal i become the message No DBus connection available is there another option to access the jnlp file without icedtea-web? Thanks for helpers Regards
