It looks like the url decode can't find the objects that are asked. when trying to map the url to the page asked in it, it can't find this page (or window in a page). I would say, first : Try the complete url to get the default page : http://localhost:8080/portal/portal/default/default or try also http://localhost:8080/portal/portal/default second, look at the description of the portal and pages, default-object.xml files (or *-object.xml) third, it may come from the error on locale : if the page is not defined for the default locale etc... but don't know exactly if this is possible... hope it can help, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3960174#...
