I guess you are talking about session time out. See: http://wiki.jboss.org/wiki/Wiki.jsp?page=HttpSessionTimeout You will need to change the session timeout in all the war files of the portal, including portal-server.war, portal-core.war... If you are only using JBoss Portal on your JBoss AS instance, it's probably less error-prome to change this at the tomcat level as explained in the first section of the Wiki.
