Open a cmd session in that Jetty directory (for this I use Microsoft PowerToys "Open Command Window" tool.)
In that cmd session, execute
java -cp . -jar start.jar
Open an IE browser and enter the address http://localhost:8080
When the web page comes up, click the Jetty test link
Go to the cmd window and enter CTRL-c to stop jetty
Now install Lift if you have not already done so.
Copy the Lift JAR file to jetty\lib
Copy the Lift Examples WAR file to jetty\webapps
restart jetty
refresh the localhost web page with the F5 key
This time click the Lift Examples link
Welcome to Lift on Jetty
