I am having trouble folowing this http://hrycan.com/2012/03/28/primefaces-lazy-loading-datatable-for-jsf2/
It says I should just run
mvn jetty:run
Check if it works after adding the following in settings.xml as documented.
org.mortbay.jetty
Also note that there are two different versions of the plugin - the older maven-jetty-plugin and the newer jetty-maven-plugin. source
