It is important to note that Jetty will not start yet. There is a safety precaution in a Jetty configuration file that helps avoid problems. We need to go edit the default Jetty configuration and remove this safety block.
You can use whatever text editor you prefer, but we're going use the "vi" editor for this example.
Let's open up the /etc/default/jetty configuration file in the "vi" editor. To do this, all you have to do is type:
sudo vi /etc/default/jetty
1. Now that you're in "vi" editor, use the arrow keys and move your cursor to the beginning of the line that states NO_START=1.
2. Hit the I key on your keyboard. This will put the "vi" editor in what's called Insert mode and allow you to insert text. You will see a white - Insert - at the bottom-left-hand side of your screen. This is how you know you're in Insert mode.
3. Type a pound sign (#) in front of the "NO_START=1 line, so that it looks like "#NO_START=1. This will comment out that line.
