The portal layout information is stored in a database. If you downloaded and are using the portal+jbossas bundle, the database is Hypersonic. You can use the Management Portlet (log in as admin and go to the admin portal) to remove the older portlet, instance and window. Or you can wipe out the database (if you are using Hypersonic) by removing the server/xxx/data directory. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129440#...
