Hi, All. I have encountered a porblem, when running jboss-forums. I use jboss-portal 2.6. I have modified the web.xml undering "jboss-4.2.1.GA\server\default\deploy\jboss-web.deployer\conf" and added myfaces 1.1.5 jars, as http://wiki.jboss.org/wiki/Wiki.jsp?page=Running2.6WithJBossAS4.2.xAndMyF....

Its error information is anonymous wrote : javax.faces.FacesException: org.apache.jasper.JasperException: The absolute uri: http://java.sun.com/jsf/html cannot be resolved in either web.xml or the jar files deployed with this application.
