you may have to add the servlet root path, of the servlet (webapp) that deliver the css file. did you try it ? that is : /ProcesosInternos/WEB-INF/css/Styles.css instead of "ProcesosInternos", it should rather be the name of the web app. the <display-name> that is in the web.xml file. sometime, there must be a "_" before the name. /_ProcesosInternos/WEB-INF/css/Styles.css you can look in one of the html page that is produce by the portal, how it is done for the layout css file. See there how it is written for those layout and theme css files. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024874#...
