NetBeans with external resources help

I used NetBeans to create a Vaadin project from a Maven archetype. I am also using Maven to package my project as a war file. To package external resources for jar files I needed to point NetBeans to the folder where my external resources are located. Since I’m making a web application NetBeans doesn’t have the same project properties as a console application jar file. I was wondering if anybody either knows how to package them together or what the correct folder structure should be.
