jboss-javaee6-webapp-blank-archetype needs to generate "resources" folder at WEB-INF level for JSF 2.0 resource libraries

Generate src/main/webapp/resources folder. The JSF 2.0 specs section 2.6.1 which says that in the deployed .war file, we can have folder called "resources" at "WEB-INF" level and any subfolder underneath that will be referred to as "library" in components like <h:outputscript library="..." ...>, <h:graphicImage library="..." .../>.
