To enter a college class I need to execute a JNPL file using the command line (because audio doesn't work from Chrome or Firefox):
user@computer:~$ sudo javaws '/home/user/Downloads/CiscoWebExServlet' Unfortunally, Instead of getting inside the meeting I get an error:
Evidence is here: Pictures
Also, here is the terminal message when I tried to load the file:
user@computer:~$ sudo javaws '/home/user/Downloads/CiscoWebExServlet' [sudo] password for user: **** selected jre: /usr/lib/jvm/default-java WARNING: package javax.jnlp not in java.desktop Iced Tea is initializing, when It's finally laoded I get the following message in the Terminal:

Edit #2: When I close the dialogue from the error I get:
